A drain trap is also known as a P trap. The name P-trap is derived from its appearance – a looped shape that resembles the letter “P”. Every time you use the sink, a small amount of standing water remains at the end of the trap. Water clogs the drain opening and prevents sewer gases from passing through the sewer pipes from the sewer system into your home. Also, see the P-trap installation diagram to understand how it works.

Also, the drain trap acts as a recovery point for small valuables like rings or necklaces when they fall down the sink. Instead of those items being washed into the main drain, they remain in the Ps-trap. It’s also through the trap where you can quickly clear blockages in the branch drain attached to the wall or from the bend of the trap.

In most cases, P-trap pipes are assembled with PVC, metal or ABS. These pipes are vulnerable to corrosion, leaks and damage as they age. The first problem you’ll likely identify is a leak between the pipe connections, and if you don’t act quickly, this problem can cause damage to your kitchen cabinets.

When P-trap leaks under the sink, it causes the water seal in the pipe to fail, releasing methane and nitrogen sulfide gases into your home. This will cause bad smell in your house.

Whether replacing an old P-trap or installing a new trap for the first time, this comprehensive guide will guide you through the process with clear instructions and helpful tips.

A Primer On

Turn off the water! Clean existing P trap (if required). Measure and cut your pieces. Assemble the wall pipe. Place the wall pipe into the waste connector. Assemble the tail and J-bend assembly. Tighten all nuts. Check for leaks.

Place a shut-off valve under your sink and turn it clockwise to turn off the water. This is an important step to take before starting to avoid accidental leaks.

If the old P-trap is in place, use your adjustable wrench to loosen and remove the tightening nuts. Start by removing the nuts that attach the old P-trap to the belt assembly, and then the nuts that attach it to the sinker tail. After loosening, carefully remove the P-trap and set it aside.

Tip: Place a bucket or bowl under the P-trap to remove it to avoid spilling the remaining water in the P-trap.

What Does The U Shaped Pipe Under A Sink Do?

Temporarily insert the J-bend into the tail of the sink so that you can measure the wall tube to length to attach the J-bend to the waist joint. If the wall tube is too long, where should you cut it with a marker. Use a hacksaw or hacksaw to cut it to the correct length.

Place the wall pipe into the waste fitting and secure the seal with a slip joint washer. Then, tighten the nut to securely connect the parts.

Place the joint nut and washer on the tail. Then, slide the dovetail into the j-bend and secure the seal with the slide joint washer. Tighten the nut to securely attach the parts. Make sure you also tighten the nut that connects the J-bend to the wall tube.

Once your P-trap is securely in place, turn the water back on and let the water run for a few moments. Check for any signs of leakage around the connections. If you notice a leak, tighten the nuts a little more until the leak stops.

If you are currently using Internet Explorer, we recommend switching to Edge or another supported browser to enjoy the best experience it has to offer. I installed a new vanity and sink and found that the sink drain doesn’t fit the p trap (also, by the way, I need tail extensions – but that’s not my question).

I’m trying to fit the p-trap, but the nut on the far end of the p-trap (pictured) is very tight despite the channel pliers. Can I cut the abs just past the elbow and will there be a piece to fit the cut end? Or do I have to cut all the way through the PVC of the sanitary piece?

It is all glued together, it should be cut in the given place and attach a wall adapter to the rest of the cut piece.

If the white pipe (PVC) is at least 1 inch away from the wall and is not covered with glue, the pipe can be cut behind the black connector (ABS). Clear the square cut. you give it, remove any cuts, add PVC primer and glue to the wall and pipe adapter and connect together and hold it for a short time until the glue takes hold.

P Trap Keep Leaking

If there isn’t enough room to get 1 inch to glue the wall adapter to the original cage, when you cut the pipe and remove the pipe, this should expose another 3/8 inch of pipe. After you connect the p-dom sink, use a “bell ring” to cover the wall adapter.

This means that the ABS p trap is useless and a new p trap must be installed.

Wall adapters come in different sizes, make sure you get the right size as well as the p trap.
