I want to tie a new toilet drain into an existing main line cleanout.its an older cast iron one that is vertcal.can I remove the plug and install a hub that will screw into it. Or do I need to install a wye so the water is directed more downstream?? :confused: the mainline runs horizontal where I want to connect it to.

Ideally you will cut a new directional fitting into the stack. It is illegal to install fittings into cleanout, but many people do it anyway!
If you plan to cut into the stack be sure to talk to us first as you will need to support the stack before using a ratchet cutter to cut into it!
Let us know...

Where would this toilet be installed ? Basement? First or second floor?Quote:

The Plumbing Page's about giving you options. Not to inflict code upon you. Let us know more about your layout. Rehards, TomQuote:

The bathroom , just a toilet and a sink, will be adjacent to another bathroom.its on the first floor with about a 2 foot crawlspace underneath it. What is the plumbers page? I don't trust myself cutting into the main stack. Sounds like a big project!!Quote:

As I've stated in a earlier post,Is the cleanout located in the crawl space? Regards, tomQuote:

Yes Tom cleanout is located in the crawlspace. Very close to where the toilet will be.You' guessed it right on.Im looking what is easiest for me without a permit. A permit in this city would kill me for this job. They would probably want me to replum whole house and who knows what else.(neighbors remodeled and went through all the headaches)if you think it will work through cleanout that would be great.Quote:

The lavatory will have to be vented out the roof or revented back into a existing dry vent in the attic. The toilet will be wet vented by the lavatory vent, Good luck, Tom
Tom meant a threaded MALE adapter... ;)
Just FYI...

Thanks Mark, It was 2 AM when I answered!
The cleanout is not wyed at all. Will there be a problem with clogging being the water is not directed downstream.its just a straight shot so drain can be cleaned either way.Quote:

After you transision to PVC with a threaded male adapter you can install a 3 X 2" wye to pick up your lavatory.. Regards, Tom
If it was small hand sink, I would say: go ahead, connect it. But with toilets, it is different story. There will be some problem with sewage flow if you connect to clean out.. Clean out has no sweeps either way. I would suggest that you cut in Y and 45 as transition piece for your toilet.
I was afraid to hear this.that old cast iron cleanout doesn't have sweeps either way.Cutting that cast iron pipe will be no fun. Under the house with not much room.even with cast iron cutters. Maybe a good hacksaw? I'm not sure about this project!! :eek:Quote:

I was thinking a wye because it will be spliced in the horizontal part of the main.it will be vented up near the toiletQuote:

in my book it's a good gamble when you look at cutting in a sanitary tee, I wouldn't use a wye) to the cast iron stack vent. It's bad enough to cut into a cast iron stack in the basement where you have room but in a crawl space. Nah!! Go for the easy way first. if that doesn't work you can always go back and do a "redo". Goodluck, Tom
Tom that sounds like a plan to me. Not much downhill slope on cleanout.but I can always redo like you said. Working on this project this weekend. Can't do much during the weekQuote:
