How to fix shower p-trap?

wmichsabre · Apr 12, 2013

So while I was putting the floor back over the top of the shower drain, I must have broken the bond between the vertical pipe and the p trap.

Is there an easy fix or do I have to tear it all out and rebuild?

Rebuild for two reasons..one because it's leaking and the second because it's an S-trap. The vent MUST come off the trap arm before that turns down. IOW, the pipe coming out of the end of the p-trap must be straight with a vent coming off of it before the waste can turn down.

Jad is correct, what you have there is very much wrong. The trap must be vented by a vertical riser within the max distance specified by your code. The pitch of the trap arm cannot exceed 2% between the trap and it's vent.

You CANNOT break the "bond between the riser and the P trap" unless it was a very poor joint in the first place, in which case it, and any others done the same way should be replaced. And, replaced with the proper slope and fittings.

Can you provide a photo of what the plumbing looks like a little further downstream??
