PR Valves and Expansion Tanks are a must here in San Antonio, due to the rise in PSI for water to the new developments in SA. By installing this on your property, you will protect your pipes and all connections of plumbing, faucets, toilets, and prevent bursting lines on your property. This is an important issue he is finding in SA. Many residents have PR Valves, but no expansion tank, which is even worse for your property lines and pipes. Once a pressure reducing valve is installed on your side of the meter, it creates a closed-looped system of pressure, since now the water heater has no let off, and if the homeowner is gone for a period of time, they will come home to a leak.
