Drain for basement bathroom
Hi:
Our house was built with roughed in plumbing for basement bathroom. I have the main drain pipe for the toilet protruding from the floor and what I believe to be a vent pipe just behind it in the middle of a studded wall also coming out from the floor. Within a few feet I have the main pipes that connect to the sewer lines. It would appear that the plumber did not allow for drain pipe for a bathroom sink. The plumber did allow for access to the main venting pipe of the house. Can I connect the sink drain to the vent pipe on the floor at the lowest point and above that point connect to the main vent pipe? |

Come 18" off the floor to the center of a 2" sanitary tee in the vent to pick up the lavatory. The vent can continue on to revent back into a DRY VENT.
If you arm out with 2" you may extend the arm 5'. If you reduce to 1 1/2" you may only arm out 3 1/2'. Good luck, Tom |
