As we all know, the bathroom sink plays an integral role in our daily lives. It’s where we brush our teeth, wash our hands, do our hair and shave, amongst other tasks that often require water or other liquids to complete. And while you probably use your sink on a regular basis without thinking about it too much, chances are you don’t understand how it actually works and what makes it work so well. Read this article to learn more about the plumbing of your bathroom sink!
Pop-up Drain
The pop-up drain is a valve that’s found under the sink, and it prevents water from spilling out onto your floor. When you’re washing your hands, for example, you should turn off the faucet with this valve to avoid any messes. The pop-up drain also has a small rod that sticks up out of it when it opens. This rod is connected to a lever on top of the sink, so when you pull it down, the rod pushes up and opens the drain.
Valve Assembly
The valve assembly is a key component of your bathroom sink. It controls how much water flows into the sink and out into the drain. There are two types of valves: a single-control valve, which is located directly below the faucet, and a three-control valve, which can be found in between two faucets or at the end of an island. If you have a single-control valve, then it’s responsible for both turning on and off water flow to that fixture.
P Trap
A P-trap, or plumbing trap, is a U-shaped pipe that has one open end and one closed end. The P-trap works to prevent sewer gases from entering your home by creating a seal at the junction where the sink drain connects to the main sewer line. Gravity causes water in the trap to form a seal between two connections. This seal prevents sewer gas from traveling up into your home through the drainpipe and makes it easier for you to smell when something has gone wrong with your plumbing system.
Shower Faucet
The most common plumbing fixture in bathrooms is a shower faucet. The function of this is to deliver water to the shower head and to be used as a regular tap when needed.
The main component in this piece of plumbing is a mixing valve that can be found inside your tank, which mixes cold water with hot water before it reaches your faucet. This allows you to maintain a comfortable temperature while taking a hot or cold shower.
