A: A water pressure regulator, also called a pressure reducing valve (PRV), controls the water pressure entering your home from the municipal water supply. It helps maintain consistent pressure and protects pipes, faucets, water heaters, and appliances from excessive pressure.

A: Most residential plumbing systems operate well between 50 and 60 PSI. Under California plumbing requirements, water pressure exceeding 80 PSI generally requires a pressure reducing valve. Excessive pressure can contribute to leaks, damaged fixtures, and premature plumbing wear.

A: Common warning signs include unusually high water pressure, fluctuating pressure, banging pipes, leaking fixtures, or water dripping from the regulator itself. Hoppers Plumbing can test your water pressure and determine whether adjustment, repair, or replacement is necessary.

A: Many residential pressure regulators last approximately 10 to 15 years, although their lifespan depends on water quality, operating conditions, and maintenance. If your regulator is aging, leaking, or no longer maintaining proper pressure, replacement may be recommended.

A: A backflow preventer is a plumbing safety device designed to prevent potentially contaminated water from flowing backward into the clean water supply. These devices are commonly used where plumbing connections could create a risk of backflow, helping protect drinking water from contamination.

A: A backflow preventer may discharge water because of debris inside the assembly, worn seals, damaged internal components, or changes in water pressure. Some assemblies are designed to discharge water under certain conditions. Hoppers Plumbing can inspect accessible components and determine whether plumbing repairs or replacement are appropriate. Certified backflow testing, when required, must be performed by a qualified tester.
