Double Leak from Bathroom Above (Found It!)
Now What?
I opened up the back of a linen closet which came me full back access to 2 tubs! The leak is coming from the drain. I will try best to describe it...
Drain comes directly down and then makes a 90 degree turn then straightens out for 4-5 inches or so then hits a tee - one side goes straight down and into the wall cavity and the other straight up as a vent I suppose. The leak is in the 4-5 inch straight section that is parallel with the floor. The piping is black ABS. I saw a nut on the vent section and tried to turn it with my hand, when I did, the 4-5 inch straight section completely separated in the middle. When I attempted to bring the 2 pieces back together, I could not figure out what kind of joint it was... both sections appeared to have the same diameter.
In any event, I believe I have full access - albeit awkward - to all piping. What is recommended at this point to fix this leak once and for all?
Thanks in advance.
