Free Home Inspector Trivia Questions and Answers

Question 1

A plumbing vent runs the danger of ___________ if it rises excessively over the roof line.

Accepted Answer

Frost Closure

Answer

If a plumbing vent pipe extends too far above the roof line, it becomes more exposed to cold temperatures and wind. This increased exposure can lead to condensation inside the pipe freezing and accumulating, potentially causing a 'frost closure' that blocks the vent. A blocked vent can lead to plumbing system issues like slow drains, gurgling noises, and sewer gas odors.

Question 2

What is suggested for polyurethane foam roofing repairs?

Accepted Answer

Elastomeric caulking

Answer

Polyurethane foam roofing is a flexible system that requires repair materials capable of accommodating movement without cracking. Elastomeric caulking is specifically designed for this purpose, providing a durable, waterproof, and flexible seal for cracks, punctures, or seams in foam roofing. Its elastic properties ensure the repair remains intact as the roof expands and contracts.

Question 3

As they rust, In masonry walls, steel lintels over doors and windows will _____________.

Accepted Answer

Make a horizontal crack in the mortar joints at the top corners of the windows

Answer

When steel lintels, which support masonry above openings, begin to rust, they expand significantly, sometimes up to seven times their original volume. This expansion exerts immense pressure on the surrounding brickwork. The stress typically manifests as horizontal cracks in the mortar joints, particularly at the top corners of window and door openings, indicating structural distress caused by the expanding rust.

Question 4

The required headroom above a stairway must be at least __.

Accepted Answer

6 feet 8 inches

Answer

Building codes, such as the International Residential Code (IRC), mandate a minimum clear headroom above all points of a stairway, including landings. This requirement is 6 feet 8 inches (80 inches). This standard ensures safe passage for occupants, preventing head injuries and providing adequate vertical clearance on stairs.

Question 5

The aluminum AWG size should be ______ if the service or feeder rating in amps is 200.

Accepted Answer

4/0

Answer

The National Electrical Code (NEC) specifies appropriate wire gauges for different current ratings to ensure safety and prevent overheating. For a 200-amp service or feeder rating using aluminum conductors, a 4/0 AWG (American Wire Gauge) size is required. This specific gauge is necessary to safely carry the high electrical load without exceeding temperature limits.
