The P-Trap: It Keeps the Stink out of Your Sink
Ever wonder what the curved pipe in the sink or toilet of your Buckhead home - the one that looks almost like a “P” lying face-down - is for? The drain trap, or P-trap as it’s commonly known, traps gas odors from the the sewer in the pipe and prevents them from coming up through the sink drain and into your home.
How Do P-Traps Work?
The P-trap holds back odors by keeping a small amount of water at a constant level at the curved portion of the P-shaped pipe. Any gas or smells that come up through your plumbing from the sewer or septic system are held at bay by the water in the trap.
Although most conspicuous under sinks because they tend to afford the easiest access, a P-trap can be found anywhere in your home that a drain to a sewer or septic system is located. Toilets, tubs and even showers all have P-traps. In these cases, however, the traps are usually hidden inside or beneath the fixture.
If you detect any strange or sewer-like odors in a room that has a drain, one of the first places to check out is the drain trap. In easily accessible places, such as under sinks or on some toilets, you may be able to check out the trap yourself. However, calling a professional plumber at Casteel is your best bet when the trap is less accessible.
Sewer gas is composed primarily of methane but may also contain toxic gases like hydrogen sulfide and sulfur dioxide, which can pose risks your health, as well as that of your family. It is nothing to take lightly. Whenever you smell an odor that should not be present in a room with a drain, act right away. First try to isolate the source of the odor - the drain, for example - and then call a plumber. Getting a faulty drain trap repaired quickly and correctly the first time will save you money in the long run while preserving your health and your home
