We have a 100-year-old house. The drain out of the second floor tub had been leaking in several places including where it met the cast-iron waste stack. It was too difficult to carve out the lead and oakum seal in the stack, so I cut off the galvanized pipe entering there and plugged it. I had plenty of room to run my own PVC pipe down the wall and tap it into the same cast-iron stack at the bottom where previous plumbers (?) had replaced that seal with god-knows-what. So, I have a new 2" PVC waste pipe with a lead and oakum seal tapped into the cast-iron Y in the basement. It's great.
Rebuilding the drain at the top was a little tricky. I didn't want to tear my frame apart, so I had very little room to work around the old waste pipes. It's fine. I build a good shape, it fit perfectly, it had a trap, a clean-out, it tapped into the old vent pipe, and it was sloped in the right direction. Gold star!
However, I had one last piece of PVC to fit. It was a six-inch straight that was connected to a T on one side and a 90 on the other. The plan was to force both ends down on the straight and twist the straight. Well, the straight twisted into 90 side before the other, and then it caught the T side, but only inserted about 1/4 of an inch before the glue set. So, on one side of that very difficult to access straight, the end of it is *not* butting up against the interior of the T. It went in 1/4", the glue set, and it's all pretty solid. But now I'm nervous.
I am guessing that since it is a non-pressurized system, that 1/4" insertion is enough to get purchase and create a water-tight seal. If I needed to, I could cut it out and replace the entire Y side. Obviously, I would want to avoid that. Thoughts?
