After our courtesy rough plumbing inspection, there were a couple of items I had to take care of. The side drain to the bathroom sink had too many connections. Only one is allowed between the trap and the wall pipe.

I wanted to move the piping into the new wall to line up with the sink placement

I replaced the polyiso “walls” over the framing to enclose the bathroom until the drywall is installed.

The dishwasher and water filter drains were draining directly into the sewer pipe. If I had put a trap under this stand pipe, like the washing machine drain, it would be OK but both of these drains needed a trap under them. The rule is ALWAYS a trap between fresh water and the sewer.

An S trap would have worked well here but they no longer meet code so I had to plug the upper part of the P-trap.

Luckily I put these two tasks on the summer list so they can be checked off!
