A pressure balance valve is a sophisticated plumbing device that reacts to changes in the pressure of the delivery water. Typically, both hot and cold water sources are fed into a pressure balance valve, and its job is to ensure that the volume of water that leaves the pressure balance valve is a constant mix of these two sources, even if the delivery pressure of the two sources changes. This is very important to keep the temperature of your shower constant even when the supply is not.
