Hi thanks for responding.
The description of the plumbing is as follows. In shower pix 1, the tube on the far left is a run from the upstairs tub trap. The trap taps into this down tub, the tube also continues up to a union in the attic and is then vented to the roof. That tubs runs into floor and merges at a junction as shown in Shower pix 4.
The tube next to this tube (next tube to the right) is being removed totally, as this used to be a drain connection for a washer that used to be on the other side of the wall.
The 3rd vertical tup is another vent tube that goes directly to the roof, and into the floor it is joined at the connetcion as shown in shower pix 4.
I plan to use Noble Company's
http://www.noblecompany.com/ sheet membranes and shower stall kits.
My question is, what type of trap should be used in this situation?
In shower pix 5 in the top right of the pix there is a old rag stuffed in the old trap. As you can also see towards the bottom right of this pix is where the trap, a vent tube, and the upstairs bath drain run into.
The area is 36 deep by 48 wide. Im planning on removing all the plumbing you see, with the exception of where all the tubes run into the bottom right of shower pix 5. See shower pix 4 for a closeup). The new drain will be centered arcoss the dimentions mentioned above.
I was told by a plumber that when burying drain plumbing in the ground the home becomes more vunerable to termites. I live in a prone area (Long Island, NY).
As for a shallow ( sorry type swallow is worng) I meant to say shallow P trap.
I would like to run all the new PVC plumbing into the junction as shown in pix 4. Is this possible? What precautions should I take when burying PVC? etc...
Thnak you so much...Bobby
