If a laundry tub waste line connects to a clothes washer standpipe, the standpipe should be at least 30 inches above the standpipe trap weir and should extend above the flood level rim edge of the laundry tub. The outlet of the laundry tub must not be more than 30 inches horizontally away from the standpipe trap.

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

Truss Uplift

A home inspector may observe during a home inspection a crack in the corner of an interior ceiling made of drywall. The crack may be at the top of the wall, and it may appear very thin or narrow (a hairline crack).

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.

Notches in the middle third of a floor joist are not permitted. Holes are not permitted to be located within 2 inches of the top or bottom edge of a floor joist. The maximum depth of a notch in a floor joist (that is not in the middle third of the joist) is the actual depth of the joist divided by 6. The maximum diameter of a bored hole through a floor joist (that is not in the middle third of the joist) is the actual depth of the joist divided by 3.
