Home Inspector Test Top Rated Home Inspector 5 — Questions and Answers
Question 1: What does the term 'polybutylene piping' refer to, and why is it significant in home inspections?
- A flexible copper alloy pipe prone to pinhole leaks
- A gray plastic pipe used from the 1970s–90s that is prone to failure and leaks (Correct answer)
- A modern cross-linked plastic pipe considered highly durable
- A galvanized steel pipe associated with lead contamination
Correct answer: A gray plastic pipe used from the 1970s–90s that is prone to failure and leaks
Polybutylene (PB) pipe was widely used from the 1970s to 1990s but degrades when exposed to chlorine in municipal water, leading to cracking and leaks.
Question 2: Which condition is a home inspector MOST likely to flag regarding a wood-burning fireplace?
- A damper that opens fully
- Creosote buildup inside the flue (Correct answer)
- A firebrick hearth extension
- Properly sized firebox opening
Correct answer: Creosote buildup inside the flue
Creosote is a flammable byproduct of burning wood that accumulates in flues and is a leading cause of chimney fires.
Question 3: What is the purpose of 'anti-tip brackets' on a freestanding kitchen range?
- To prevent the stove from sliding on smooth flooring
- To stop the range from tipping forward when a heavy load is placed on an open door (Correct answer)
- To anchor the range to the gas line during earthquakes
- To prevent children from turning the front burner knobs
Correct answer: To stop the range from tipping forward when a heavy load is placed on an open door
Anti-tip brackets anchor the rear leg of a freestanding range to prevent the appliance from tipping when someone sits or leans on an open oven door.
Question 4: A home inspector observes that a deck is attached to the house with lag screws driven through the ledger board into the rim joist. What additional concern should be checked?
- Whether the deck boards are cedar or pressure-treated
- Whether flashing is properly installed at the ledger to prevent water intrusion (Correct answer)
- Whether the deck color matches the house siding
- Whether the deck joists are 16 or 24 inches on center
Correct answer: Whether flashing is properly installed at the ledger to prevent water intrusion
Improper or missing ledger flashing allows water to enter behind the board, rotting the rim joist and potentially causing deck collapse.
Question 5: What does 'galvanic corrosion' mean in the context of a home inspection?
- Corrosion caused by high levels of chlorine in the water supply
- Accelerated corrosion when two dissimilar metals are in contact in the presence of an electrolyte (Correct answer)
- Rust formation on steel fasteners exposed to exterior weather
- Chemical breakdown of plastic pipe due to UV exposure
Correct answer: Accelerated corrosion when two dissimilar metals are in contact in the presence of an electrolyte
Galvanic corrosion occurs when two dissimilar metals like copper and galvanized steel are joined, causing the less noble metal to corrode faster.
Question 6: Which of the following represents a 'limitation' that a home inspector must disclose in their report?
- The inspector chose not to test the HVAC system
- Finished walls prevented inspection of hidden framing and wiring (Correct answer)
- The inspector did not have the proper license
- The inspector tested only half of the GFCI outlets
Correct answer: Finished walls prevented inspection of hidden framing and wiring
Limitations are conditions beyond the inspector's control, such as inaccessible areas, that prevent full inspection of a component or system.
Question 7: When inspecting a home built before 1978, which hazardous material concern is MOST specific to that era?
- Formaldehyde in composite wood products
- Lead-based paint on interior and exterior surfaces (Correct answer)
- PFAS chemicals in drinking water systems
- Volatile organic compounds in carpeting
Correct answer: Lead-based paint on interior and exterior surfaces
Lead-based paint was commonly used in homes before 1978 and was federally banned for residential use that year; its presence must be disclosed in real estate transactions.
