Well... I thought it must be right after the sanitary tee, but before the stack... Well, not. I took apart the rubber coupling and tried to snake out the 2 inch pipe and the snake went down easily several feet. So I realized that the tub was slow independently from the sink. I cleaned the drain of the tub, and voila, tub is fine. Then I tried to snake out the sink drain after removing the trap. I hit the obstruction about 2 ft into the pipe. I tried everything: slow, fast, back, forth, but unable to break up or pull out the clog. I put it together and now the sink is completely stopped.

I guess my only choice now (short of calling a real plumber) is to cut the old sanitary tee out of the pipe, and snake it from down up. Then replace the tee with PVC (I think the sanitary tee can stay, after all that was not what was clogged), and put in a cleanout, just in case.

The machine and cable you use is very important what exactly are you using post pic’s if you can. Especially the cable head.

if your going to replace the tee(and you should), use a combination wye- 1/8 bend. Join it to the existing line with a no-hub coupling like your current coupling. Use a pvc coupling on the tub side. This is the proper fitting when going from vertical to horizontal.

I bought the material today, the combination tee-wye, a cleanout, etc. I'll do the job tomorrow or as soon as I can find time. I'll post some pictures when I'm done. I hope I won't do anything ridiculous...

reuse rubber PVC coupling?


Here is the promised photo:



It works, but I'm not all that satisfied. For two reasons.

1) First I cut the vertical sink pipe too long, and since I glued on a minimal length vertical PVC to the tee-wye, I had to cut more of the galvanized steel pipe. After that it became too short, so the rubber coupling is barely hanging on both the PVC and the steel. Of course I could make the PVC going up a little longer, but then I would have to buy a new tee-wye, wye, threaded whatever-it's-called, and redo the cementing. I'll just watch carefully, and if it starts to leak I will have to do it.

2) This problem existed before I even started this work, but I only discovered it after putting things together: the tub pipe doesn't have a drop. I'm sure water is pooling inside the pipe, so it's only a question of time until I develop a leak or blockage. We will remodel the whole bathroom eventually anyway, so I just hope it will work until then.

BTW the clog was in the vertical sink pipe. Once the sanitary tee was cut off, I went up vertically with the snake and within one minute, the clog was gone and I took a shower of dirty water.

You can replace the vertical no-hub coupling with a rubber fernco. They are slightly longer (maybe 4"?) and would work just fine.
