Hi All –

I am new to the form, but have been reading many of the posts for the last few weeks. My question is regarding plumbing/venting of a second story half bathroom that I have gutted and I am preparing to remodel.

I am adding a shower and in doing so relocating the sink and toilet. The toilet is being moved approximately 3.5’ and the sink is being relocated to make room for the shower (Sterling Corner Neo 38x38). The bathroom is a small space with just enough room to accommodate the planned arrangement.

I have uploaded a two page PDF for review. I am requesting assistance/feedback with my proposed plumbing layout. As diagramed do I have sufficient venting for the Shower and sink? As a proactive measure should I install a Sudor vent for the sink?

Thanks for the help!

What's the two triangles on the 2"drain line? You show a 3 X 2" Sanitary tee laying on its side. Can't do that. Change it for a 3 X 2" combination wye and eighth bend. The shower will wet vent and the lavatory will have to be vented either by a revent or , if local codes permit, a AAV. You're good to go! Good luck, Tom

sb1 - The two trianges depict a union. I am not sure if I will need to join at that point or simply use one solid piece.

Thanks for the insight on the 3 x 2 combination wye. I will do exactly that.

So to confirm - sufficiently vented - no sudor vent needed?

Not what I said Paul, I said,

You will either have to run a revent back to the vent or a Studor Vent.

The two trianges depict a union. I think you mean a coupling. Unions aren't used in drainage. Regards, Tom

Ah - got it - I was thrown off by the AAV term. I will use a Studor for the sink...
Thanks a lot for your help. This site is fantastic.

AAV= Air Admittance Valve= Studor Vent Tom
