Pressure Regulators

Water pressure regulators or pressure regulating valves (sometimes called PRV units) are required by District Rules and Regulations and must be kept in working order.  In most instances, your regulator can be found inside your house. PRVs protect your water heater and other household plumbing.

This means periodic testing by reading the in-house pressure, shutting the supply line off, turning it back on, and reading the pressure again.  The regulator should hold at approximately 50 to 60 psi.  Most regulators are adjustable.  If the regulator does not adjust or does not hold pressure at 50-60 psi, it should be replaced or repaired.    For detailed information about how the regulators work, why they are needed, what they look like, and how they can be maintained, please see:
