What is the purpose of the S bend in the toilet?
An S -shaped trap is also known as an S – bend . Because of its shape, the trap retains some water after the fixture’s use. This water creates an air seal that prevents sewer gas from passing from the drain pipes back into the building.
Do showers have S bends?
The trap in the shower drain works like the one beneath the kitchen sink. The S-shape allows water to drain vertically upon clearing through the S-shaped curve rather than draining horizontally. The bottom area of the shower trap holds some water that seals the drain against sewer gases.
What kind of Bend do you need for a toilet?
A closet bend is a wide-sweep 90-degree elbow used for toilet installations. Measure the distance from the outlet of the closet bend to the soil stack, and use a spirit level and tape measure to make a mark on the stack that will give the waste pipe connected to it a slope toward the stack of 1/4 inch per foot.
What to do if your toilet drain line runs away from the wall?
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.
What is the distance between the toilet and the vent?
The Toilet’s Trap Arm Length (aka Trap To Vent Distance). The toilet’s trap arm, also referred to as the fixture drain, is the pipe between the trap and the vent. This distance depends on your local plumbing code. If you’re in the IPC, there is no limitation in length for the toilet’s trap arm. That’s right, no limitation!
Do you need to trim the top of a toilet closet?
Check that the pipe slopes 1/8 to 1/4 inch down to the fitting. (If necessary, you can trim the top of the closet bend after the flooring has been replaced.) Once you are sure the toilet drain setup is correct, mark the alignment of the fittings and disassemble. Prime and glue the pieces. Support the closet bend with a strap.
Where does the closet bend go in a toilet?
The closet bend attaches to two different pipes including the soil pipe, a drain pipe directly below the toilet that connects directly to the toilet flange, and the drain stack, the major drain line in your home. To install it correctly, dry fit the pipes first before bonding them permanently.

What do you need to plumb a closet Bend?
Getting the right fall is the most important part of plumbing the closet bend. Measure and cut a length of PVC pipe to match the distance between toilet flange and where it connects to the drainpipe in the wall. Use a pipe saw to cut the pipe. Attach the pipe to the fitting in the wall first and to the closet bend second.
How do you install a toilet in a closet?
Cut a short section of PVC pipe, called a “stub,” to fit between the top of the closet bend and the toilet flange. To obtain this measurement, hold the drainpipe at the correct slope and then measure from the inside lip of the toilet flange to the inside lip of the closet bend.
