Pressure Balanced Thermostatic Mixing Valves: How Do They Really Work?

15 January 2019

When it comes to the water supply in your home, not all features are made equally. The concept of running water, with hot or cold as an option, is something that most people wouldn’t have dreamed of before the invention of plumbing. Nowadays, we take the ability for granted. With that being said, there are even better ways to enjoy the benefit of hot and cold water on demand. We are talking about pressure balanced thermostatic mixing valves. Today, we are going to break down these PBTMVs in order to describe to you how exactly they operate.

Pressure Balanced Thermostatic Mixing Valves: Operation Guide

First and foremost, we need to discuss what exactly makes up a pressure balanced thermostatic mixing valve due to the fact that these are not common products. Essentially, these specialised valves are installed inline with your plumbing system at home. The goal of this specialised valve is to essentially provide you with two tangible benefits: hot water on command and temperature control so as to prevent any potential injury due to scalding. These valves are ideal for homes with young children or senior citizens who cannot be put at risk due to temperature changes. With that out of the way, let’s talk about how the system itself works by breaking it down to two concepts.

1) Pressure Balanced Valve – A pressure balanced valve has the sole job of providing a steady stream of water to your shower or taps. A pressure balanced valve will work to accommodate any potential changes in your pressure such as a toilet flushing or someone running the water in a different room. By balancing the pressure, your stream of temperature controlled water is never put in jeopardy.

2) Thermostatic Mixing Valve – A thermostatic mixing valve works to blend both hot and cold water in order to provide a steady stream of safe temperatures. You get to decide just how hot it is that you want your water to be. Fluctuations in water temperature can lead directly to potential injury which is what makes the thermostatic mixing valve so important.

With a pressure balanced thermostatic mixing valve installed into your home, you can benefit from a steady stream of pressure balanced water that never gravitates out of your temperature range. You’ll have a constant temperature that sits no different than +/- 1 C’ no matter what goes on in your system.
