Where does the drain line and the vent line go?
If the toilet drain does not connect directly to a vent, you must find another way to vent it. If the drain line runs away from the wall where you want the vent, use a reducing Y and a 45-degree street elbow to point the vent line toward the wall. The horizontal vent pipe runs right next to the closet bend.
Where does the Revent pipe attach to the drain line?
A revent pipe, also called an auxiliary vent, attaches to the drain line near the fixture and runs up and over to the main vent. It may attach directly behind the fixture or to the horizontal drain line.
Where is the best place to reroute water drain pipes?
Where to reroute pipes depends largely on code, but most rerouting jobs direct pipes above ground through the attic. Walls, baseboard boxes, closets and ceilings are also viable places to route pipes with the proper insulation.
How to Run Drain and vent lines for your DIY bathroom?
You may need another elbow (of any degree) to position the vertical vent where you want it. If the vent wall is opposite the drain line, use a reducing Y and a street elbow. The fittings can be pointed straight at the wall or at an angle, as needed. Start with a length of 3-inch pipe long enough to reach the basement or crawlspace.

Is there a way to reroute a bathroom drain?
Rerouting bathroom drainage in a home that has a standard wood subfloor set on joists is just a matter of getting the pipe and vent configurations correct. If your foundation is slab-on-grade, however, rerouting the drains means breaking out concrete to tie the new drain into the main drain.
