Can you connect a trap to a vertical drain?
Connecting a trap to a vertical drain with a wye fitting and a 45-degree elbow seems like a good idea. But it’s not. As water drains down the steep slope at the wye, it can create a siphon effect such that water will be sucked out of the trap. And the empty trap will allow sewer gas to flow into your home.
What should the width of a vertical drain be?
Light-weight drains have a width to thickness ratio of 30-35. It is desirable for the surface area, which will permit seepage into the drain, to be 0.2-0.3 in 2 (150-200 mm 2) per 0.4 in (1 mm) length.
Do You need A P trap for a drain waste pipe?
The drain waste pipe needs a cleanout at its highest end, but removable toilets and sinks with removable P-traps count as cleanouts. For bath drains, shower drains, and floor drains it is ok to connect ABS pipe down through the floor to the trap.
Can you use gray water to Prime Drain U bend?
This uses gray water from the sink to prime the drain U bend so it does not use any additional potable water. It will not automatically work when leaving the house unoccupied for a long vacation so you may need to get someone to visit the house while you are away to turn on the tap to the sink
How do you attach a wye to a drain line?
Push the pieces into each side of the wye and give them a quarter-turn twist. Here’s where it gets tricky—you need to prep and manage multiple glued connections in a matter of seconds. You must prime the couplings, the pipe ends of the existing drain, and the pipe ends of the new wye assembly you just made.

What kind of fitting do you use to tie in drain line?
(Note: when tapping into a horizontal drain, always use a wye fitting, never a tee wye). You want 1⁄4-in. gaps on either side—just enough to insert the piece and slide the fittings into place.
Can a PVC pipe be cut into a drain line?
After cutting, let any residual water drip out. While you’re waiting, cut two pieces of new PVC pipe to approximately 7-1/2 in. each, which will leave enough pipe to slide into the socket of both the wye and the coupling. Dry-fit the new wye assembly and test-fit it in the open section that you cut out of the drain line.
