Hello, I am in the process of finishing my basement. The house already had a toilet and sink roughed in and I hired a plumbing contractor to install a shower drain by tying into the existing drain. No problems, I have finished building my walls, tile work, set the shower pan, etc. I am now ready to set my toilet, however when I removed the black cap from the toilet rough-in, about 2" down (where I expected to see water or at the very least nothing) there is what appears to be another white colored cover over the drain. This cover unlike the first one does not have any markings on it indicating how to remove it like the first black cover did (it had clear markings that said to "knock out" here).

My question is, Is this a secondary cover for code purposes ? My thought is to drill a small pilot hole into it and see if I can pull it off.

Any suggestions?

BTW, when I had the contractor out to do the shower drain, he did nothing to the toilet rough in area since it was already there. Both of us assumed that it was all ready to go and since he tied the shower drian into it, I have to believe that it is all connected. I suppose I am being overly cautious, but I have never seen this before.

Thanks,
Dave

Hi Dave,

Sounds like a plastic test cap to me. Just knock it out and trim it away.

The toilet is indeed connected to the sewer. I hope your plumber vented the shower when he tied it into the toilet dischage line. It's against code to drscharge a major fixture past a uinvented minor one. If hrdidn't want to run a shower vent he should have connecred into the sink drain and be wet vented by it. You do have the sink vented don't you? Regards, tom
