Default how would I fix this? pic included

I have a leak where this 2" pipe cracked where the red line is drawn. How would I repair this? Could I just cut about a foot above the crack and replace the section? Is that T-shaped joint still OK? Would I be able to remove the part of the pipe that that is still in the T shaped joint or once these things set is it impossible to clear out? I have never worked with piping before so although it looks somewhat simple in how to videos I know appearances can be deceiving.



Any help is greatly appreciated.

Nope, the fittings are permanently glued together. Since the fittings are so close together, you'll need to replace the entire assembly. It may seem like a lot, but it's just a sanitary tee, two street 90s and a regular 90. You'll also need to get a length of pipe, ABS cement, a repair coupling, and 1-2 regular couplings.

Make sure you fit everything together before you start gluing. Also make sure you plan out the order of assembly so you can get the last fitting installed without "painting yourself in a corner." The repair coupling will make it easy, but they're a little more expensive than a regular fitting, so if you can work out a way to avoid it you'll save a few $s.

BTW, I would make the horizontal section as long as you can get to fit. The existing is pretty close to an s-trap which is not allowed since it's easy for it to get sucked dry.

Hi Voam,
You would cut it out and put in a new tee, trap, and standpipe. If you can find the black ABS pipe you can cement it in using a coupling on the bottom then use a banded coupling such as a Fernco Proflex on the top. Repair couplings have a nasty habit of setting up to quickly especially with ABS and causing problems.

However, in your area I anticipate ABS being hard to find and white PVC pipe is much more common. PVC and ABS cannot be cemented together so if you make up the new section in PVC I would use a banded coupling such as the Fernco Proflex on both the top and bottom of the repair to attach it.

One other item of interest is the white pipe coming into the wye at the botto near the floor. What is it and can you post another picture showing more of it?

Is this line coming down from the kitchen sink above?

Thank you for the detailed replies. The white line is from the heater air conditioning unit. I think it is the from the condenser from the AC. (not 100% sure about that, but definitely from heater /ac unit).

That may be problematic as well...

Do you get nasty sewer smells in your home during the winter months?

No we don't. But you do raise a disturbing point.

I'd be interested to see what a bead of silicone would do for the problem before "opening a can of worms".

Not much and a very nasty mess if the cracking continues which it will...

The line is incorrectly tied in and I'm surprised you are not getting sewer gases drawn into your HVAC system...

The easiest way to repair this is to use one of these. 3 in. EPDM Rubber Hub x Hub Flex Coupling - 808 c156-33 at The Home Depot only in 2". Cut the pipe at the leak and slide the coupling over the pipe and tighten. Have a cold beer.
