Do you have a device like the one pictured? If yes, then the water pressure on your home or property is being regulated, or reduced. Residential water pressure should not exceed 80 pounds per square inch, or PSI. Sometimes water is supplied to houses at 100 or even 150 PSI. A water pressure gauge allows property owners to test thier water pressure. A water pressure regulator can be installed at the service point of entry to the home. The regulator will protect the properties water distribution system. When water pressure in a residence is too high, it can result in pipe damage, wasted water and leaks. Leaks caused by high water pressure sometimes appear intermittently, as when toilets run when not being used.
