P Trap

tate16t

I'm replacing my bathroom petalstool sink. I removed the sink from the wall and water lines. I left part of the "P" trap in place (the down spout). My wife ran the washer machine and water came out when the washer went to it's rinse cycle. Is this normal? Should I have left the the "P" trap on?

My home is on a slab and the washer is on the same floor.

Sounds like you may have some kind of venting issue in your plumbing, or maybe a clog.

The pee trap is designed to keep noxious waste gasses from entering the house.

You say the washer is on the same floor....is it also backed up to this bathroom or close?? It may be on the same stack as the bathroom, which, by all rights shouldn't matter, but for some reason it may be flowing through the wye, and coming out in the bathroom. Probably wasn't noticable before with everything hooked up because the drain elevation was higher than the wye, now it's not. Seems you would have noticed some gurgling and such tho, in the bathroom sink, when the washer was draining...... may have some debris buildup in the drain below the wye........but i would wait for the real plumbers to chime in....i'm just doing my own process of elimination here, giving you things to think towards...
