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.

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

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).

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.

Crawlspaces

Access openings must be a minimum of 18 inches high by 24 inches wide. Access to all under-floor spaces must be provided with access openings through the floor not smaller than 18 inches by 24 inches (457 mm by 610 mm).

Check for downspouts diverters not discharging water far enough away from the house. Check floor lawn irrigation systems spraying water against the house foundation, and check for gardens or planters that are up against the house. These may be causing wet soil pressure problems for the structure.

The weight and pressure of the dry soil may affect and crack a foundation. There is wet soil that can exert a force against a foundation.
