Many of you have read my reports where I mention the importance of rodent-proofing new and existing houses. This is crucial. We only build houses for a couple of reasons: to keep the elements off our heads and to choose which animals we’d like to live with. The following article by Jessica Kane speaks to identifying the signs of an invasion of the unwanted. Enjoy!
Telltale Signs of Rodent Droppings and Rodent Infestation in Your Home
In order to fully protect your family from the harm that can be caused from rodent infestation of your residence, you need to familiarize yourself with the telltale signs of rodent droppings in and around your home. You must understand that rodent infestation at your home will not only result in physical damage to your home, it can expose your loved ones to potentially serious diseases.
What do Rodent Droppings Look Like?
There are three types of rodent droppings that a homeowner in the United States needs to be aware of, including:
The feces from each of these animals are different in their appearance. A mouse dropping looks rather like a grain of brown rice. A mouse produces the smallest droppings of the three types of rodents that can infest a U.S. residence. Mouse droppings normally are thin with at least one end that is pointed
Rat droppings are larger than those produces by a mouse. A rat dropping tends to be oblong in shape. A rat dropping typically is slightly wider in the middle area of a feces from this rodent. A rat dropping usually is darker in color that a rat feces. This type of dropping usually has a shiny and moist appearance. Over time, a rat dropping becomes a bit lighter in color.
Although an adult squirrel is larger that a mouse or rat, a squirrel’s dropping is close in size to that of the much smaller mouse. A rat dropping is smaller than that of a rat. A squirrel dropping is the darkest type of rodent feces.
Location of Rodent Droppings
The location of rodent droppings is also indicative of the type of animal that may be infesting your home. Rats and mice tend to leave droppings in lines, but not in one location. They tend to leave lines of droppings in locations in your home that they use to get from one location to another.
Squirrels tend to establish what fairly can be called latrines, when it comes to their droppings. In other words, if you’ve some type of squirrel infestation, you are likely to find growing piles of squirrel feces in or around your home. As an aside, while rats and mice are likely to nest in different parts of your home, is squirrels infest the interior of your home, they are likely to be found in the attic.
Rodent Droppings as a Sign of Infestation
If you are attempting to confirm whether or not some type of rodent has infested your home, you will also want to pay attention to the color of feces. As rodent feces age, they become lighter in color.
If the rodent droppings you find in your residence appear lighter in color, even with something of a gray hue, they are not fresh and have been around for some time. If you only identify rodent feces of this nature, with this color, you likely do not have a current rodent infestation. Rodents were present in your home in the past, but by feces that appear lighter in color, with a grayish hue, and dry, odds are that whatever rodents that were once in your home vacated.
Health Dangers of Rodent Feces
In addition to being indicative of rodent infestation, feces can also be highly dangerous in and of themselves. For example, rat mouse feces can carry the hantavirus. A human infected by the hantavirus can end up seriously ill or even die.
You need to keep in mind that live hantavirus persists in rodent feces, even after the droppings dry. Dry feces crumble easily. If infected by the hantavirus, a dry rodent dropping can crumble and release the virus into the air. When that happens, the situation becomes very serious. A person can breathe in the dust from the feces, infected themselves with the hantavirus.
Rodent Feces Cleanup
Because of the potential for dangerous pathogens contained in rodent feces, care must be taken when droppings are cleaned up. Indeed, consideration should be given to retaining the professional services of a rodent feces cleanup specialist. If you are going to attempt to cleanup rodent feces, you must utilize appropriate personal protective equipment, including:
- Smock or other covering
- Mask or respirator
Due to the risk of airborne virus infection, a respirator is recommended over the use of a mask. As noted previously, professional rodent feces cleanup is recommended over self-help when it comes to cleaning up what can be dangerous droppings.
5 Things You Should Stop Throwing Away
Wastefulness has increased in modern times because consumers can find low-cost, disposable products made from inexpensive, easy-to-manufacture materials. These products harm the environment in a variety of ways:
– Waste causes the destruction of forests and fields to create larger landfills.
– Biodegradable items in landfills decompose to create methane and other greenhouse gases.
– Burning trash creates harmful smoke that pollutes clean air.
– Animals eat plastics and plastic breakdown releases toxic chemicals into the ground and water supplies.
Garbage bags, waste disposal trucks and landfills often contain items that people can effortlessly recycle, upcycle or reuse. You simply need to rethink how you deal with trash:
Fruit and Vegetable Waste
Moldy or damaged fruit and vegetable waste is 100 percent biodegradable. In nature, waste plants feed microorganisms, insects and animals and decompose into plant soil nutrients. Instead of tossing whole fruits and vegetables or cuttings into the trash, make nutrient-rich composted fertilizer for your potted plants and garden. Drill a few out-gassing holes into the sides of a sturdy lidded container and then fill the container with starter soil, earthworms and leaves. Shred fruit and vegetable waste into small pieces and then add it to the container.
Tip: Collect seeds before you add the waste to the compost bin.
Instead of throwing the rolls used for packaging toilet paper, paper towel, wax paper, plastic film and other materials into the trash, shred the cardboard into small pieces to add to a compost container or fold some rolls, fill them with dirt and use them as seed starter containers that you can later cut away and compost when you’re ready to plant. Cardboard rolls can also replace some plastic storage containers. Fold and tape one end of a roll and then fill it. For example, use a paper towel roll as a makeshift medical kit or utensil holder when camping.
Tip: You can also recycle cardboard rolls at your local municipal or waste paper recycling area with cardboard boxes.
Most grocery stores have outdoor bins for recycling plastic bags. These bins also accept other types of plastic bags, including shipping and frozen food bags. Turn boxed cereal and raisin bags into snack storage or an extra layer of protection around wrapped frozen meats. Never again pay for plastic “shake” style food preparation bags. These bags are the perfect alternative for coating meats and vegetables with flour, sauces and seasonings.
Tip: Use cereal and raisin bags as countertop food preparation mats to reduce cleanup.
Old TVs, remote controls, phones, music players, tools and other electronics contain hazardous materials like arsenic, barium, cadmium, lead and mercury. Harvest screws, bolts and wires to use elsewhere. Power cords often contain copper wires that you can reuse in craft projects or recycle with metal containers to make a little side cash. If you just want to toss your electronics, take them to an e-waste recycling facility.
Tip: Find a repair and resale shop that pays cash for broken electronics.
You can lessen the level of waste that comes from disposable face masks that you use to stop dirt, dust and other small particles from entering your nose during indoor and outdoor repair and craft projects by breaking them down into smaller reusable parts. Remove the nose bridge metal wire and recycle it with metal recycling or reuse it in craft projects. Cut off the stretchy ear loops to reuse as ties in your home.
Tip: Always wear gloves when harvesting these parts if dealing with a face mask worn in public during cold and flu season.

So, you’ve found a house that appeals to you and fits your budget. You have made an offer which was accepted by the seller, and are ready to have the house inspected prior to closing the deal. If you’re like most folks in this market you will have a 5 – 10 day option period in which to do this and many other things. Is that long enough? Probably not. Why?
1. Competent home inspectors are few and those few stay busy, as one might expect. The odds of getting a skilled expert within such a short window of time are definitely against you.
2. The inspector’s job is to identify significant issues found during an inspection and to direct you to the type of professional needed to further assess and offer remedial options. Even if you land an excellent inspector within your short time frame, you may not be so fortunate with the recommended repair persons. Like their inspector equivalents, experienced structural engineers, HVAC technicians, master electricians, et al., stay occupied.
This leaves you in the position to rely upon the B or C team to educate you regarding your prospective new home’s condition. These will usually come in the form of the obsequious that flock around your real estate agent for crumbs in the form of referrals, or those whose only drawing card is availability. Either of these is not likely to notice that the predominant angle of your future new home is not 90°, the roof leaks, or much else of significance.
What’s the answer? Extend your option period, if possible. If the seller is reluctant and your agent is incapable of negotiating an extension, you probably should move on. Rushing into a large purchase like this without being fully prepared benefits only the seller and his agent who is being paid to rush you.
How To Avoid Being (Completely) Screwed When Buying A New Home in Texas
When purchasing a new home from a Texas home builder, you are entering a veritable mine field from which you will not escape totally unscathed, all prudent preparations on your part notwithstanding. Regardless how intelligent, street smart, savvy, or tough-minded you envision yourself to be, you are outgunned from the start. Your opponents are corporate production builders who spend more money on lobbying the Texas legislature than nearly any other group. The laws regarding home building are written to protect them – not you. Unconvinced? Let’s take a closer look.
When a conflict arises from your learning that your builder is shoddily constructing your new home (which is inevitable), you have little viable recourse. All builders’ contracts contain a clause that limits your legal action against them to binding arbitration. This is an expensive process that is heavily weighted in the builders’ favor. The arbitrators are always from the American Arbitration Association. This group is in close affiliation with the National Association of Home Builders (NAHB). From their site: “As the provider of choice for dispute resolution services, the AAA through its National Construction Dispute Resolution Committee (NCDRC), has worked closely with the industry to develop the Construction Industry Arbitration Rules and Mediation Procedures and other project specific approaches to prevent and manage conflict.” These rules are written by the builders and for the builders.
The building codes adopted by the various municipalities in the state of Texas are based upon those authored by the International Code Council (ICC). While, at first blush, appearing to be an independent code-authoring organization, further investigation reveals undue influence from the NAHB. Just one glaring example is that, from its inception in 2000, the ICC’s International Residential Code stated its purpose in 101.3 as “The purpose of this code is to provide minimum requirements to safeguard life or limb, health and public welfare.”
Now let’s watch the changes that occurred in 101.3 during subsequent versions.
The 2003 version states, “The purpose of this code is to provide minimum requirements to safeguard the public safety, health and general welfare, through affordability, structural strength, means of egress facilities, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards attributed to the built environment.” This is an improvement. The 2006 version states exactly the same. All is well so far.
The 2009 version introduces a fly into the ointment: “R101.3 Intent. The purpose of this code is to establish minimum requirements to safeguard the public safety, health and general welfare through affordability, structural strength, means of egress facilities, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards attributed to the built environment and to provide safety to fire fighters and emergency responders during emergency operations.” Now, the minimal building code, which is the worse way one can legally build a house, hinges upon affordability and not safety. And, the picture gets even more bleak.
Municipal Building Inspectors
When a municipality in Texas adopts a building code it becomes and has the force of law. The municipal building inspectors are tasked with the job of enforcing this code, or are they?
In IRC 104.1, we find, “The building official is hereby authorized and directed to enforce the provisions of this code . . .” So far, it sounds like the onus is on the building official to enforce the building code. But wait.
The rest of that citation goes like this, “. . . The building official shall have the authority to render interpretations of this code and to adopt policies and procedures in order to clarify the application of its provisions. Such interpretations, policies and procedures shall be in conformance with the intent and purpose of this code. Such policies and procedures shall not have the effect of waiving requirements specifically provided for in this code.”
That still sounds like the building official must enforce the spirit, if not the letter, of the code. However, on January 19, 2005, Greg Abbott, Attorney General of Texas (yes, the same bozo that would have you elect his sorry self for governor) rendered a rather specious opinion on the matter that concluded with this, “Local Government Code section 214.212(c)(1), which permits a municipality to adopt local amendments to the International Residential Code, does not limit the municipality to adopting only local amendments that are equivalent to or more stringent than the standards of the International Residential Code.” In other words the municipal inspectors can do as they please. The building code be damned.
Remember that the building officials work for the corporations that are the municipalities. It is their job to protect that corporations and not you. They are also stuck between the developers wanting to build in their jurisdictions and the politicians they work for. So who will be on your side?
Hire an attorney before you sign any paperwork with any builder. Not just any attorney will do. Your run-of-the-mill, paper-shuffling bar-passer will not suffice. You need an attorney who is experienced in dealing with builders and their contracts. If you need a referral, contact me.
Strike the binding arbitration clause. Add to the contract that your builder shall repair everything that your third-party inspector finds to be in conflict with the letter and spirit of the adopted building codes. You should also insist that the builder supply you with a complete set of the construction documents (blueprints). Do not fall for his story about them being copyrighted. While they are indeed copyrighted, the copyright only prevents you from selling the plans or using the plans to build a house, it does not prohibit your possessing a set of plans to the house you have bought. As the owner of the home your possession of the plans would fall under the doctrine of fair use.
Hire a competent home inspector. The minimum requirements for this inspector are, (1) Significant prior home construction experience, (2) International Code Council certification as an R-5 Combination Residential Inspector, (3) Licensed by the Texas Real Estate Commission or the Texas Board of Professional Engineers.
Grow a set of cojones. Take charge of the project from the outset, stay on top of every phase of construction, and do not succumb to the builder’s bullshit and outright lies. Take no prisoners. Make no mistake. This is an adversarial relationship you are entering into with your builder. He is not your friend.
If you follow the three steps above you will not end up with a perfect house. You will also not be on the receiving end of quality construction. These are unattainable goals in the current Texas home building milieu. You will, however, be in charge of an otherwise uncontrollable process that will result in a substandard house replete with defects.
Questions to Ask Your Home Inspector or Things Your Home Inspector Won’t Tell You
While the Internet can be useful when searching for some types of information, it should come as no surprise to anyone that it is also rife with misinformation. The term “to google” is, after all, synonymous with to search, and not to research. It is a good search tool and not so good when relied upon as a sole research method.
If you feel that you have done your due diligence by googling what questions to ask your prospective home inspector, think again. Bullshit is prevalent in our society. By bullshit I mean misinformation that is not exactly a lie and certainly not the truth. It is misleading nonsense used to further the writer’s or speaker’s agenda.
If you google “questions to ask your home inspector”, “things your home inspector won’t tell you”, or the like, you’ll be up to your ears in search results from any number of groups with vested interests in selling their positions or products. These will run the gamut from groups like Zillow/Trulia, real estate brokerages and agents, new home builders, mortgage lenders, the bought-and-paid-for main stream media like CNN, Fox News and MSNBC, brain-dead bloggers, forums populated by the over- and under-medicated, etc. ad infinitum. Most of these have simply either found a list of questions and outright plagiarized it or have lightly edited it and called it their own. In other words, the lists you find, by and large, will be merely regurgitated bullshit, and not even the original stuff.
But, enough about the misinformation; how does one find useful information on this subject? Glad you asked. Perhaps a useful way to approach this is to simply make a list of the most common misconceptions floating about in cyberspace, and address each of them head on. For the sake of both brevity and clarity I will handle each of these as they pertain to home inspections within the state of Texas, where I am intimately familiar with the territory and laws. I will also limit the list to the ten questions I most commonly am asked.
Q1: What does your home inspection cover?
A1: Home inspections in the state of Texas are governed by the Texas Real Estate Commission (TREC). While this may appear to be (and certainly is) tantamount to the fox guarding the hen house, it is nevertheless how those folks in the capital of Austin repay us for electing them. The TREC has adopted a set of standards for home inspectors, which includes a detailed list of what must and what must not be inspected. This list can be found at: http://info.sos.state.tx.us/pls/pub/readtac$ext.ViewTAC?tac_view=5&ti=22&pt=23&ch=535&sch=R&rl=Y
This is the minimum standard for a Texas home inspection. Said differently, it is the worst way a home inspection can be legally performed. While a few highly-qualified inspectors, such as this author, may exceed this standard, most do not. Many are either unwilling to meet, or incapable of meeting this standard.
Q2: How many home inspections have you performed?
A2: While this is essentially a good question, the person asking it will likely have no idea of what a good answer might sound like. The American Society of Home Inspectors requires 250 inspections for its certified members. While that may sound like a lot, it is not even enough to begin to get the drift of inspecting a house. The state of Texas has no such requirement. Once licensed, you are good to go ahead and begin on-the-job training while inspecting houses for unsuspecting buyers. My opinion, based upon 18 years experience in the field, is that, after completing 1000 inspections, an inspector may just begin to think of himself or herself as minimally competent.
Q3: Will you climb on the roof?
A3: Without first seeing the roof, this is not possible to answer. There are many roof surfaces that are not safe to walk on and should not be walked on by anyone but a certified roofing contractor wearing the proper OSHA-required fall protection gear. Certain roof surfaces, such as slate, faux slate, clay tiles, standing-seam metal, old, worn asphalt shingles, etc. are not safe to walk on. Additionally, asphalt roofs should not be walked on during the extreme temperatures we experience during North Texas summers. Most inspectors do not carry or use ladders in excess of 18 feet in height. This may not be sufficient to safely reach the lower roof surface. Even it is, the upper roof surface may be out of safe reach. Most roofs can be properly inspected from a ladder at the eaves and with binoculars from the ground. Roof surfaces with excessive pitches (>6/12) are also unsafe. No inspector in his right mind will risk his life to inspect your roof. It may be interesting to note here that even professional roofing contractors will often not mount a roof to give a replacement estimate. They use http://www.eagleview.com/ .
Q4: Do you use an infrared camera?
A4: This is one is especially exasperating to me. Infrared cameras measure heat differences translated to a digital screen to form a picture. These are sometimes useful during home inspections under the ideal conditions. While they are just another tool in the box, many inexperienced inspectors hard-sell their use to prospective clients because the clients do not fully understand what the cameras are capable of and the inspectors have no other skills to hawk. It makes more sense to ask the inspector if he uses a flashlight, ladder, electrical meter, moisture meter, et al. These tools are more often employed. Let us put this into perspective. Would you consider asking your doctor if he uses a stethoscope, thermometer, blood pressure cuff, MRI machine, etc.?
Q5: How long will the inspection take?
A5: Without seeing the condition of a house it is infeasible to predict with any degree of accuracy how long the inspection will take. On relatively new houses, a range of 1.5 to 2 hours should be reasonable for a highly experienced inspector. It is also possible to spend 3-4 hours on a 2000 s.f. house that is a poster child for materials/systems atrophy and deferred homeowner maintenance, or a flipped (investor’s) house (lipsticked pig).
Q6: How much will it cost?
A6: This is typically the first question asked. It is always an indication to me that the caller has done no research. My fees have always been listed on my website. Most inspectors do not post these so that they can adjust their fees according to time available, house location, etc. Fees vary widely from area to area. They are generally higher in the large metropolitan areas. Generally speaking, the minimum fee for a competent inspection in my area will be somewhere in the range of $450. Those asking less are usually lesser qualified and unable to demand the going rate.
Q7: What type of report do you provide and when will I receive it?
A7: The TREC promulgates the report format for Texas inspectors. This can be seen here: http://www.trec.state.tx.us/pdf/forms/insp/REI-7-4-PropertyInspectionReport.pdf
All inspections performed on substantially completed houses must be reported on this form.
The TREC requires that inspection reports be delivered within 3 days. This is unreasonable. Most inspections happen during a short option period. Inspection reports should be made available on the same day as the inspection. One caveat here is that on-site inspection reports usually indicate that your inspector is a minimalist. There is no reporting system available for portable computers or mobile devices that can substitute for a well-researched and documented report. Any report that is under 60 pages in length is less than fully informative.
Q8: Can I attend the inspection?
A8: This question should never be asked. Assume that you will be attending the inspection. Also assume that you should leave the inspector to perform his observations and draw his conclusions prior to his discussing his findings with you. Inspectors who allow you to “tag along”, and perform a walking tutorial with you while inspecting the house are practicing what is tantamount to texting while driving. Nothing good will come of it.
Q9: Are you familiar with the area in which the house is built?
A9: This assumes that houses are somehow significantly different than others. This is simply not the case. With a few exceptions such as extremely custom modern homes, over-the-top eccentric homes, or extremely old historic homes, all homes are essentially built the same way and of the same materials. Some people like to think that the houses they are considering buying are unique. This is almost always not the case.
Q10: Do you carry professional liability (errors and omissions) insurance?
A10: All licensed inspectors in the state of Texas must carry professional liability insurance as a prerequisite to licensing or license renewal. If you understand what this insurance is you will see that this is a stupid question. Professional liability insurance simply provides the inspector with an attorney should you choose to sue him. You get to hire your own. It provides no benefit for you.
Now, let’s take a peek at some of the questions I would ask, if I were hiring a home inspector. Brace yourself. They will be quite different that the list above.
Q1: Have you ever built any houses? If so, how many? What was your role in the home building process?
Comment 1: A person who has built several houses possesses an intimate knowledge of their materials, systems, structure, function, et al. that cannot be replicated through classroom experience. Driving by a new house under construction or sweeping the floors behind the construction crew in a house being built does not count. Being the general contractor or builder only counts if you actually took an active part in the construction, i.e. sawed wood, hammered nails, etc. Riding around in an oversized. noisy pickup truck and writing checks to subcontractors does not make one a builder.
Q2: What certifications do you hold pertinent to inspecting houses?
Comment 2: A home inspector license is not a certification. It is merely a license to do business. Certifications are available from many organizations. The most relevant are those provided by the International Code Council (ICC). At a minimum, any inspector should hold an R-5 Combination Residential Inspector certification from the ICC. Beyond that there are others available from the Post-Tensioning Institute, the National Fire Protection Association, et al. Note that serving as some type of officer in this or that inspector organization is an affiliation and not a certification. It is an indication that the officer is politically motivated and has way to much time on his hands. It has absolutely no bearing on knowledge of the profession.
Q3: How many real estate agents or brokers refer you on a regular basis?
Comment 3: Most home inspectors rely solely upon referrals from real estate agents and brokers who have a vested interest in finding few if any problems with a house. This unduly influences and severely limits your inspector’s judgment when reporting adverse conditions to you. The answer to this question should be very few or none.
Q4: Are you a sole proprietor or a member of a multi-inspector firm? Are you a franchisee?
Comment 4: Competent professional inspectors find it a challenge to find enough business while attempting to compete with the agent-pleasers (ass-kissers). The ability to procure sufficient business to keep several inspectors employed is one sure sign of an inspector that is tied at the hip with brokers and realtors. Franchisees are usually those who are too inept or shiftless to properly build a business from the ground up. They believe that one can purchase credibility by buying into a franchise scheme.
Q5: Do you carry general liability insurance?
Comment 5: General liability insurance is not required for Texas home inspectors, but is a must in order to protect home sellers and buyers alike.
Q6: How many continuing education hours do you obtain annually?
Comment 6: The TREC requires home inspectors to obtain 16 hours of CEUs each year, see: http://info.sos.state.tx.us/pls/pub/readtac$ext.TacPage?sl=R&app=9&p_dir=&p_rloc=&p_tloc=&p_ploc=&pg=1&p_tac=&ti=22&pt=23&ch=535&rl=218
Unfortunately, the TREC approves only education vendors who are willing to pay them to be approved. Most of the better and relevant CEU courses available for other professionals such as building inspectors, engineers, architects, and builders are not approved the TREC. Go figure.
Inspectors at the top of their game usually obtain >30 CEU hours annually.
If you have corrugated stainless steel tubing (CSST) installed in your home for gas distribution you are strongly urged to read the following information. I have long been against the idea of installing CSST for gas piping. As with many other building materials that have been developed to decrease costs to the home building industry, the manufacturers of this product seem to have cut too many corners. In the process they have increased the need for precise installation of the product and decreased the safety of homeowners saddled with these, apparently unsafe, installations.
I have monitored the CSST installations over time for performance and have made many changes accordingly to the wording in my inspections reports. However, my low opinion of the product has not changed. In fact, it is now my position that I would not have this product in my own home under any circumstances. I also strongly urge any of my clients with CSST piping in their homes to consider the following information and exercise due diligence regarding this product.
This is the current report verbiage I use. It is subject to change as more information comes to me.
The CSST gas lines do not appear to be properly bonded as required by NEC 250.104(B):
(B) Other Metal Piping. Where installed in or attached to a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122, using the rating of the circuit that is likely to energize the piping system(s). The equipment grounding conductor for the circuit that is likely to energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.
The CSST gas lines do not appear to be properly bonded as required by IRC G2411.1.1 (310.1.1) CSST. Corrugated stainless steel tubing (CSST) gas piping systems shall be bonded to the electrical service grounding electrode system. The bonding jumper shall connect to a metallic pipe or fitting between the point of delivery and the first downstream CSST fitting. The bonding jumper shall be not smaller than 6 AWG copper wire or equivalent. Gas piping systems that contain one or more segments of CSST shall be bonded in accordance with this section.
The CSST gas lines do not appear to be properly bonded as required by the National Fuel Gas Code (NFPA 54) 7.13.1 Pipe and Tubing Other than CSST. Each aboveground portion of a gas piping system other than CSST that is likely to become energized shall be electrically continuous and bonded to an effective ground-fault current path. Gas piping, other than CSST, shall be considered to be bonded when it is connected to appliances that are connected to the appliance grounding conductor of the circuit supplying that appliance. AND 7.13.2 CSST. CSST gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent.
Additionally, the CSST gas lines do not appear to be bonded as per the manufacturer’s installation instructions. Gastite (and others) recommends that all continuous metallic systems be bonded and grounded. The owner should confirm with a licensed master electrician or electrical engineer that each continuous metallic system in a structure has been bonded and grounded by an electrical professional in accordance with local building codes. This should include, but is not limited to metallic chimney liners, metallic appliance vents, metallic ducting and piping, electrical cables, and structural steel. This is a fire and explosion hazard which must be immediately addressed.
Your are strongly urged to have this system inspected and properly bonded by a licensed master electrician or electrical engineer prior to the end of any time periods associated with the purchase of this home.
The CSST gas piping is subject to damage from nail strikes, electrical wiring shorts, lightning strikes, et al. both during and after construction. The entire system is not accessible for a visual inspection and the presence or absence of damage to this piping cannot be ascertained without destructive forensic examination of the house which is beyond the scope of this inspection.
Even when the flow of leaking gas does not cause a fire or explosion, the possibility of gas poisoning is very real.
Concealed hazards may exist. You are strongly urged to have this system leak tested and thoroughly inspected for condition and proper installation by a licensed master plumber with experience both CSST installation and in gas leak detection, as well as the CSST manufacturer, prior to the end of any time periods associated with the sale or purchase of this home.
Research suggests that, at a minimum, and in addition to proper installation and bonding, the installation of lightning protection systems as per NFPA 780 and gas excessive flow valves (EFVs) may be essential in the presence of CSST, though not the end of due diligence. Finally, replacement of the CSST with threaded steel gas piping may be the only method certain of avoiding the risks involved with this product.
CSST was deemed by a jury to be a defective product. See:
ATTENTION: FIRE AND EXPOSION HAZARD!
Based upon the evidence currently available, it is this inspector’s opinion that the CSST gas piping may be unsafe even if installed as per the manufacturer’s installation instructions.
You are strongly urged to consider having this system completely replaced with threaded steel gas piping prior to the end of any time periods associated with the purchase of this home and, more importantly, prior to occupying this home. Additionally, the owner of this home should be advised to immediately vacate the home and have the system either made safe (if possible) or replaced with threaded steel piping prior to moving back in.
