How far below drain pipe can p-trap be?

24 inches

Does p-trap have to be directly below drain?

The “P” trap SHOULD be directly under the drain, but no more than a few inches off center of it, if conditions require it.

Does p-trap have to be level?

Plumbing Codes Restrictions. Most Plumbing Codes place restrictions on how a p-trap is used and manufactured. You must install a trap level in relation to its trap seal. If the trap isn’t level, it can be susceptible to back-siphonage.

Can you install a p-trap backwards?

The outlet end of the trap pipe should be lower than the inlet when installed properly. The example shown has it backward, which creates a trap seal more than 4” and makes the drain more likely to clog—and that’s a long explanation for why a backwards trap is a bad thing.

Do you need a trap on a washer drain?

When hooking up a new washing machine, some people look for a convenient drain line and simply install a pipe that extends to the washer. The lack of a P-trap exposes the area to sewer fumes and the lack of venting will cause the drain to run sluggishly and overflow. Washers, like all fixtures, need a trap.

Is it OK to have 2 P traps?

It is perfectly fine to have (2) “P” traps , one on eash sink of a (2) sink setup. As long as the “P” traps are not Double Trapped ( more than one trap serving a fixture ) then it is fine as long as the weir is sized correctly.

What if P-trap is too high?

When the trap is too deep, liquid may flow through it too fast, which can lead to siphoning of the trap seal and sludge buildup. The drain connection at the wall is too high on this sink, resulting in a 9-inch-deep trap seal — 5 inches deeper than is allowed by code.

What happens if P-trap is installed backwards?

In the bottom picture we can see that when the trap is installed “backwards” the distance labeled “B” is much greater than distance “A”—–a much higher hill for the water to get over. Well eventually the trap will clog up with debris and water will just not drain properly.

Can A P trap be lower than drain pipe?

You attach the p-trap directly to the drainage and manuever the p-traps exits into you existing drain. It is not ideal to have the p-trap below the the exit drain because water gravity has to force the water out instead of it flowing downwards naturally.

Where does the P trap go in the basement?

The basin drain goes straight down into the basement, and the trap sits between the floor joists. This may be an option if everything is located appropriately. Some codes limit the length of the tailpiece to something like 24″. It’s intended the tail piece be as short as practical.

How big is the gap between the P trap and the floor?

It is currently a bit less of 20in from the floor to the center of the pipe and the gap to the p trap is about 8cm. Is there something in the code that tells you the minimal high??

Can a trap swivel pick up a low drain?

They may need to put a street 45 at the wall to swing off to the side and then use the trap swivel to pick up the drain. The drains are two low, and normally you would try to lower the drain in the wall. Sometimes you can use the lo-inlet though and get by.
