Hi Everybody.
I need to replace one of our laundry sinks in the basement and am going to need to connect some new PVC to the existing (lead?) drain that comes up from under the slab. The other laundry sink has already been re-plumbed, so I have an example to work off of, but I’m not sure what all the parts I’m seeing are.
Here are 2 pictures of the conditions… existing.jpg is the plumbing that will need to be replaced, and complete.jpg is the other one that’s already done.
So, how do I connect to the old drain line?
thanks.

Marnold,
Thats some wild looking stuff in photo # 1. If the pipes our close in size you could use a no hub fitting, Its a rubber fitting with strong clamps, but wait to the Wethead posts here he's a plumber. I only know the 3 rules of plumbing!& i am still in rehab.
First tell me what the 3 pipes go to if you can. From left to right.
You do realize this lead stuff is artwork don't you? And you are going to destroy artwork. How does that make you feel?
Just kidding... OK? I would replace it with modern PVC too.
Oh, very funny... artwork is definitely one word for it...
The 2 pipes that go vertically are both vents... the one on the left has been cut off about 10 feet to the left and basically vents to nowhere... the one to the right connects to PVC above the sink. I've included a photo.
My plan is to eliminate get out the sawzall, cut the drain 5 or 6 inches above the slab, cut out the vent on the left (which is abandoned) and connect to the PVC vent above. Then I'll remove the old sink and replace it with a smaller one so I have a clear floor space in front of the new electrical panel and can have that final inspection.
The question is... how to connect to the lead pipe that comes out of the slab?
thanks very much for your help!
rubber "no hub" fittings is the only way to go and convert the whole mess to ABS or PVC, either is easy, cut pipe with a good handsaw, glue the fittings(just get the right glue) and dont mix abs and pvc pipe and fittings
I suggest rubber couplings rather than no-hub for this application. Less chance of damaging the lead. Be careful as you cut it. Use a finer tooth blade.
Thanks very much for the advise... I picked up all the parts and pieces today and will hopefully get to the actual work tomorrow.
For now, though, it's time to light the grill and crack open the beers!
Happy 4th!
post me a pic or 2 when you get it done ok? have a good one.
