roughed in basement plumbing
Posted by GJB on May 02, 19100 at 15:47:08:
I am in the process of finishing my basement bathroom and have come up with a few questions that
I need answered.
I have three pipes coming up through the bassement floor (1) toilet drain 4" PVC, (2) vent stack 2" PVC,
(3) I believe it is intended to be a shower or tub drain 2" PVC stub. The drain pipe is not located
convenientlyto place my shower over it. I want to run the drain from the shower above the floor to this
drain by raising the floor in the shower by a few inches. This will not allow for an airtrap directly below
Has the "roughed in" plumbing accounted for that with a trap below the stub?
How much grade does this above floor drain pipe need as it travels the 4 feet from shower to drain?
(I've heard 1/4" per foot)
Any help would be appreciated.
