Home Inspector Test Top Rated Home Inspector 4 — Questions and Answers
Question 1: A home inspector observes that bathroom exhaust fans vent into the attic space rather than to the exterior. What is the concern?
- Increased electricity costs from air leakage
- Moisture-laden air can cause condensation, mold, and wood rot in the attic (Correct answer)
- Reduced bathroom heating efficiency in winter
- Noise from fan operation travels into living spaces
Correct answer: Moisture-laden air can cause condensation, mold, and wood rot in the attic
Venting exhaust fans into the attic introduces warm, humid air that condenses on cooler surfaces, fostering mold growth and structural damage.
Question 2: What does 'kickout flashing' protect against in residential construction?
- Prevents insects from entering the wall cavity at the eave
- Diverts water away from the wall where a roof slope meets a vertical wall (Correct answer)
- Secures the bottom course of siding against wind uplift
- Protects the foundation from frost heave
Correct answer: Diverts water away from the wall where a roof slope meets a vertical wall
Kickout flashing deflects roof runoff away from the wall cladding and into the gutter, preventing water intrusion at this vulnerable intersection.
Question 3: Which of the following is NOT within the standard scope of a residential home inspection?
- Testing GFCI outlets for proper function
- Identifying visible evidence of active termite infestation
- Determining the exact remaining lifespan of a roof in years (Correct answer)
- Noting the absence of smoke detectors
Correct answer: Determining the exact remaining lifespan of a roof in years
Home inspectors assess current condition and visible defects but cannot predict exact remaining service life of components.
Question 4: What is the significance of a 'S-trap' in plumbing, and why do inspectors flag it?
- It is an outdated pipe material known to corrode quickly
- It can lose its water seal through siphoning, allowing sewer gases into the home (Correct answer)
- It is a trap design used only in commercial buildings
- It lacks sufficient water flow capacity for modern fixtures
Correct answer: It can lose its water seal through siphoning, allowing sewer gases into the home
An S-trap can self-siphon and lose its water seal, permitting toxic and odorous sewer gases to enter the living space.
Question 5: During an inspection, a home inspector discovers asbestos-containing floor tiles that are in good condition. What is the appropriate recommendation?
- Immediate removal is required before occupancy
- Monitor the tiles and leave them undisturbed; removal is only needed if they become damaged (Correct answer)
- Seal all tiles with two coats of polyurethane immediately
- No action is needed because asbestos was approved for flooring
Correct answer: Monitor the tiles and leave them undisturbed; removal is only needed if they become damaged
Intact asbestos-containing materials that are not friable pose minimal risk; disturbance or removal can actually release more fibers.
Question 6: What is the primary function of a pressure relief valve (PRV) on a water heater?
- To regulate incoming water pressure from the municipal supply
- To release excess pressure and prevent the tank from exploding (Correct answer)
- To control the water temperature at the tap
- To prevent cold water from entering the hot water lines
Correct answer: To release excess pressure and prevent the tank from exploding
The T&P (temperature and pressure) relief valve opens automatically to release pressure if the tank overheats or pressure exceeds safe limits, preventing a catastrophic rupture.
Question 7: A home inspector notes that the main electrical service panel is located inside a bathroom closet. Why is this a concern?
- Moisture in bathrooms can damage electrical components and create shock hazards (Correct answer)
- Building codes require panels to face magnetic north for safety
- Panels in closets use more electricity than those in open spaces
- Bathroom panels are only allowed in homes built before 1978
Correct answer: Moisture in bathrooms can damage electrical components and create shock hazards
Electrical panels must not be located in bathrooms because moisture and steam create shock and corrosion hazards, and is prohibited by the NEC.
