Hi everyone, happy new year. I am planning on adding a small, full bathroom in the corner of the basement. There is an existing sewage ejection pit for the floor drain and I plan on breaking out concrete and tying into it with a 3" PVC waste line.
I want to be sure the plumbing is vented properly. One existing wall is rough framed against the poured concrete wall and I can go up through the wall upstairs above the kitchen sink, behind a cabinet, and tie into that vent for the basement and not have to make a finished repair of the drywall.
The shower is a 3' X 4' across the furthest end and the drain would be 8 1/2 ft., away from the pit, next a sink, then the toilet would be 33" from the edge of the pit to it's center. One challenge is that nothing is in a straight line and I don't think I should tear out the rough framed wall and break out a trench next to a poured concrete wall. I thought I should run the line straight from the pit to the toilet and on past in a straight line until I can intersect the shower drain at a 45 degree, horizontal angle. Between the 45 el and the toilet I could use a horizontal Y to branch over and up through the wall for the sink drain and on up and then over to tie into the vent from upstairs. I would also vent the (unvented) pit with that same vent.
Would everything be wet vented properly? Where should I reduce the 3" line for the shower P trap and sink? I have attached 2 scale drawings to show the location of the planned drains and my proposed layout of the waste line and trench.
Isn't there a rubber gasket made to install in the hole I make in the pit wall for the 3" waste line? Should it be silicone caulked also or pour concrete around that joint when I cover the excavation?
