Is it advisable to put a couple 45s in a main drain line? Is there a way to install a drain trap next to a main trunk line?
Our septic system back up over the weekend and pointed out two problems caused by the previous owner of the home. Luckily the problem made itself noticeable when we were doing laundry, not flushing the toilet ! The new shower drain was bubbling and water was leaking in the basement in two places.
The previous owner added a handicap shower to the downstairs bath. They tapped the drain into the line from the kitchen sink.
Leak 1: They cut the line to install everything and put it back together with a rubber sleeve and metal screw clamps. The sleeve was barely on the one side and there was actually a tiny gap at the top. When the water backed up it started leaking from the top of the pipe. It was messy with a pipe FULL of water, but I got that fixed.
Leak 2: The main drain line from the kitchen is directly under the shower drain. There is no trap, and it leaks when it backs up!
Here is my plan for Leak 2. Cut the main drain line again. Install a pair of 45s prior to the new shower to jockey the line to the opposite side of the joists. Install a T next to the shower. Install a trap under the shower and run it into the top of the T.
Is this the proper, the best, and the easiest way to fix this?
