Which of the following is a common indicator of asbestos-containing pipe insulation in older homes?
Answer: Gray or white corrugated cardboard-like wrapping on pipes
Asbestos pipe insulation often appears as gray or white corrugated wrapping around older heating pipes and may look like plaster or cardboard.
A home inspector finds that the dryer exhaust vent is made of flexible plastic accordion-style duct. Why is this a concern?
Answer: Plastic ducts reduce dryer efficiency and are a fire hazard due to lint accumulation
Plastic flexible dryer ducts sag, trap lint, restrict airflow, and are a recognized fire hazard; rigid metal ducting is required.
What is the minimum slope required for lot grading immediately adjacent to a home's foundation to promote proper drainage?
Answer: 6 inches within the first 10 feet
Standard guidance requires a minimum 6-inch drop within the first 10 feet from the foundation to direct water away from the structure.
A home inspector notices aluminum branch circuit wiring in a home built in the 1960s. The MOST important concern is:
Answer: Aluminum wiring at connections can oxidize and overheat, creating a fire hazard
Aluminum wiring connections can oxidize and loosen over time, causing resistance heating that is a significant fire risk.
When inspecting a gas fireplace, a home inspector should verify that the glass panel:
Answer: Is ceramic or tempered safety glass rated for high heat exposure
Gas fireplace glass panels must be ceramic or tempered safety glass to withstand the high temperatures without shattering.
Which of the following is NOT a standard method for radon mitigation in a home with a basement?
Answer: Increasing indoor radon concentration to equalize with outdoor levels
Increasing indoor radon concentration is never a mitigation method; all valid methods dilute or redirect radon away from living spaces.
A home inspector finds a pressure relief valve (T&P valve) on a water heater that has been removed and capped off. This is:
Answer: A serious safety deficiency that could result in a catastrophic explosion
The T&P valve is the only safety device preventing a water heater from exploding under excessive pressure or temperature; disabling it is extremely dangerous.
