What is the pressure balance valve?

pressure balance valve is a sophisticated plumbing device that responds to changes in the supply water pressure. Both hot and cold water sources are usually fed into the valve and its task is to ensure that the volume of the water that leaves it is a constant mixture of these two sources, even if the pressure of two sources changes. It is very important that the shower temperature is constant, even if the supply is not. Temperature extremes in the opposite direction also caused problems, with people slipping and falling, trying to avoid suddenly very cold shower. These problems get worse when very young or very old people are involved. Home owners can also make the valve in an older house, but will probably require the help of a certified plumber. In older homes, the new valve may not work very well if there is insufficient water flow due to clogged water pipes or poor water pressure related to the age of the plumbing system. Certified in such situations can help in such situationsPlumber, because it will be able to determine the extent of the problem in advance and what will be required to provide a functional solution.

For the highest comfort in the shower, homeowners can also consider installing a thermostatic valve. These cost more, but provide much better temperature control. The big disadvantage of the pressure balance valve is that it can provide limited flow control. The thermostatic valve can provide a full flow control range while still providing water at a constant temperature.
