Sometimes, though these valves wear out, break, or are positioned incorrectly and that can cause uncomfortable shower temperatures.

Why does my shower keep changing temperature?

The shower temperature changes when you flush (or use water) because the pressure in that supply line has changed. This means less supply to the mixing valve in the same setting. Modern thermostatic mixing valves are designed to keep the total pressure constant.

How do you adjust the temperature on a single handle shower faucet?

Is a mixing valve necessary?

To begin with, we need to understand what a thermostatic mixing valve (often abbreviated to TMV) is, and determine its primary use in various situations. In a sentence; thermostatic mixing valves are designed to maintain and restrict the mixed hot water to a desirable, selectable temperature.

How do you adjust a sink mixing valve?

The retail cost of the valves at some of the larger retail chains is just under $100. A plumber may charge $100-$200 to install it. In Part Two of this post, we take a look at the benefits of using a thermostatic mixing valve, and why turning the water temperature down is not the solution.

Where is the thermostatic mixing valve located?

A thermostatic mixer can be installed in the hot water heater itself or on a specific plumbing fixture, such as through a shower valve.

Why does my water temperature fluctuate?

If your water temperature fluctuates, the pressure-balancing valve might be to blame. Your pressure-balancing valves open and close depending on your water flow in your plumbing system. If cold or hot water levels drop, a broken pressure valve could cause a drop in water pressure.

How does a shower mixing valve work?

How Does a Mixer Shower Work? A mixer shower, as its name suggests, mixes a hot and cold water supply in a valve to reach your chosen temperature before it reaches the shower head. In order for a mixer shower to operate properly, the hot and cold water supplies need to be fed into the system at the same pressure.
