Kitchen Plumbing Components: The P-Trap

Most of the plumbing in a house remains hidden behind walls, in ceilings and floors, or in rooms people rarely enter. Ironically, a part of the plumbing that people often see, the U-shape in the drainpipes beneath the sinks, is one that few people understand. Perhaps because we are so used to seeing this shape, we don’t stop to think about what it actually does.

That U-shape is called the p-trap, and it serves a key function in your plumbing. Sometimes it will require repairs and unclogging; when that happens, call for experts in plumbing in Blue Bell, PA from Carney Plumbing Heating & Cooling. We offer same day service, satisfaction guaranteed.

The Basics of the P-Trap

The p-trap (so-called because it resembles a capital P when viewed on its side) traps water after it runs through the drainpipe. Water comes to rest in the dip, and this forms a liquid plug against the escape of sewer gas. The decomposition of waste further down the pipe will rise to exit the drain, but the water in the p-trap is sufficient most of the time to block it.

A p-trap can dry up if a sink isn’t used for a long period of time, such as a sink in a guest room. When this happens, sewer gas will start to escape from the waste water lines and enter the room, creating an unpleasant odor. You can fix this problem easily by running water down the drain for a minute to fill up the trap once more.

The p-trap can also trap other items aside from water: hair, soap scum, grease, and small objects like toys that fall down the drain. This will eventually lead to clogging. Sometimes a plunger will do the job of clearing the clog, but if that doesn’t work, you’ll need to call a plumber to use a drain snake, hydro-jetter, or even dismantle the p-trap’s pipes to eliminate the blockage.

Problems with the p-trap are simple issues for plumbers to resolve, so don’t let mistakes from do-it-yourself solutions beyond a plunger make the issues worse.
