Completing Roughed in basement bathroom

PHomeOwner · 01-21-2011, 10:08 AM

Hi guys,

i wanted some input on how to tie a new drain into the existing roughed in work already done. From the picture i have drawn a line from where the new pvc pipe will come from. I know that it needs to be vented as well, so i guess the single pipe at some point will be "T'd" off. Any ideas on how this should be done?

Thanks in advance.

That all depends.. What are you running it to? Sink? Laundry? Bar?

this is running from a new sink that i will be putting in.

Well then my next question is.... I see the Pipe for the water Closet... Is that another Pipe in the floor for a Shower? or is it already piped in for a sink? What will you be doing with that Pipe... Sorry I am sitting at a Job site And I am having the worst time seeing that Pic for some reason.

Note to self anytime you piss off an inspector be ready to pay for it! Been here for 2.5 hours for an 8:00 appoint that was 45 minutes away

thanx for all the replies Docwhitley

ok, so the smaller pipe is for the shower drain, which i will be building later on, so it will be used.

hopefully your day gets better.

Ok then It is possibly a simple fix... On the Vertical Pipe there is a "T" this is where your sink connects. Is there a way that you can cut out the T and have enough room to run the Pipe either in front of it or behind it? I think that the pipe you are thinking about connecting to is the vent for the Shower. Depending on how that is piped underground could cause you to have an S trap that will siphon the trap. If you can cut into the pipe with the T is your best option if not depending on if this is going o be an everyday bathroom or not would decide how I would pipe it in. If not then I would cut out a section of the Pipe Put a Y in at the bottom for the drain and then a couple feet away on the drain I would add anther y and run it up and 90 over connecting back to the vent pipe... Hope that makes sense

thx again for the reply Docwhitley,

This is to be used as an occasional bathroom. I initial idea was also to try and run the pipe behind the existing one, but there is not enough room for that. If i run it in front, then i have to build the wall out a little bit, which I'm trying to avoid doing. the pipe that you are suggesting adding a "Y" at the bottom, it the longer pipe that runs up the wall?

It appears it's already stubbed out for a lav on the right side of the picture.

i know it's already stubbed out on the right side. but, by putting the sink there, it would not be enough room on that wall, thus i am want to place the sink directly across from the existing plumbing.
