MetroWest Plumbing Question: What is a U-Bend?

If, like many homeowners, you do not understand much about your indoor plumbing, you are far from alone. A lot of homeowners give very little thought to the very fact that their plumbing is there at all. Of course, this is only true when the plumbing is operating properly. When you experience problems with your plumbing it is much more difficult to ignore just how necessary the effective, efficient operation of this important system really is. At Basnett Plumbing & Heating, we understand that many homeowners are not very well-versed in plumbing terminology, but a basic idea of some essential plumbing components is a bit of knowledge any homeowner in the MetroWest area can benefit from.

One very important little piece of your plumbing system is the U-bend or drain trap underneath all of the sinks in your home. This innocuous bit of pipe serves a very important function. Thanks to its shape it dips below the drain pipe under your sinks. While water is running it forces water through this drain trap, up and out of the system for disposal. When the water is shut off, though, the last bit of water from the sink has no way to escape, and becomes trapped in the drain trap.

This may sound like a problem, but that is actually exactly what the U-bend is designed to do. By maintaining a small amount of water in the pipe system below your sinks foul sewer odors are prevented from coming up through the drains in your sink. If there is a clog in your sink drain due to hair or other debris it will often become lodged in the drain trap, making for easy clog removal that anyone can handle. Simple pull off the drain trap and clear it out before replacing it.

The expert plumbers at Basnett Plumbing & Heating know that only a certified plumber should handle any repair or maintenance service on your plumbing system in the MetroWest area. A little working knowledge of components such as your drain trap, though, will allow you to take care of a very minor issue on your own, though.
