Under The Sink Mixing Valve

Under the Sink Mixing Valve

The mixing valve under your sink is responsible for mixing hot and cold water to provide you with the desired water temperature. It is a crucial component of your plumbing system, and if it fails, you may experience problems with water temperature or even no water flow at all.

There are two main types of mixing valves: single-handle and double-handle. Single-handle valves are the most common type and are typically found in newer homes. They have a single lever that you move up and down to adjust the water temperature and left and right to adjust the water flow. Double-handle valves have two separate handles, one for hot water and one for cold water. You adjust the water temperature by turning both handles simultaneously.

Mixing valves can be made from various materials, including brass, plastic, and stainless steel. Brass is the most durable material and is typically used in commercial applications. Plastic is less expensive than brass but is not as durable. Stainless steel is a good choice for areas where corrosion is a concern.

If you are experiencing problems with your mixing valve, there are a few things you can check before calling a plumber. First, check to see if the valve is loose. If it is, you can tighten it using a wrench. Next, check the aerator on the faucet. If it is clogged, it can restrict water flow and cause the valve to malfunction. Finally, check the water pressure. If the water pressure is too low, it can prevent the valve from working properly.

If you have checked all of these things and the valve is still not working properly, you will need to call a plumber. A plumber can diagnose the problem and make the necessary repairs.
