Inspection of private water sources, such as a well, is beyond the scope of a home inspection.

The following are 13 requirements for a discharge pipe serving a TPR valve:

Temperature and pressure-relief (TPR) valves are safety devices installed on water heating appliances, such as boilers and domestic water supply heaters. TPRs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels.

Whirlpool/jetted bathtub fixtures must be installed according to the manufacturer’s recommendations. The bathtub may be filled with water and tested during the rough-in plumbing inspection.

Watch this and again NEVER skip a sewer scope! New construction also, we have found many new builds with sewer line issues

Discharge, Loop and Air Gap

The dishwasher discharge hose should be connected to the waste tee or disposer inlet above the drain trap. It is recommended that the drain hose either be looped up and securely fastened to the underside of the counter, or be connected to an air gap.

I grew up on a farm = eat your food do not waste it! Debris from the disposal will clog your drains in enough time

Unvented Crawlspaces

In most climate zones, conditioned crawlspaces perform better than vented crawlspaces in terms of safety, health, comfort, durability, and energy consumption. Research has demonstrated how these conditioned crawlspaces also do not cost more to construct than vented crawlspaces. Crawlspace venting is a widely accepted business practice across the U.S. However, in humid climates, the warm humid air entering the crawlspace is more likely to condense on crawlspace framing than it will to help dry out the crawlspace. This is because the outside air can often have a dew point that is higher than the interior crawlspace framing surface temperature. As evidence, existing vented crawlspaces have experienced serious moisture and mold problems, costing builders and homeowners significant resources to repair.

Collar Ties

Collar ties span between and connect opposing rafters, and they are typically placed in the top third of the attic spaces. Collar ties hold the rafters down against the ridge board and, to an extent, help prevent rafter spread. Home inspectors should take note of attics without collar ties, especially where the rafters run perpendicular to the joists. Collar ties must be at least 1x4 (nominal) and spaced not more than 4 feet on center. A lack of collar ties may allow roof rafters to separate and cause sagging of the roof's ridge and structure.www.nachi.org
