What Is PRV Replacement?
PRV (pressure reducing valve) replacement is the installation or replacement of a valve that reduces incoming water pressure to a safe level (typically 50–80 PSI). In Orange County, municipal pressure often exceeds 80 PSI in many areas; code and best practice call for a PRV to protect pipes, fixtures, and water heaters. A failed or missing PRV can cause leaks, fixture wear, and water heater issues. We install quality PRVs and can add or check an expansion tank for thermal expansion.

Our PRV Replacement Process
Pressure Measurement
We test your static water pressure at a hose bib with a calibrated gauge to confirm the PRV has failed and document the incoming pressure from the Orange County municipal supply.
PRV Removal
The main water supply is shut off, the old PRV is cut out or unthreaded, and the pipe ends are prepped for the new valve—cleaned, deburred, and properly aligned.
New PRV Installation
A new, appropriately sized PRV is installed with unions or compression fittings for future serviceability, and the outlet pressure is adjusted to 55–65 PSI per manufacturer and code guidelines.
System Pressure Verification
We turn the water back on, recheck pressure at multiple fixtures, confirm no leaks at the valve, and test the thermal expansion tank to ensure it's properly charged for the new operating pressure.

PRV Replacement — Frequently Asked Questions
Many Orange County areas have municipal water pressure above 80 PSI. Code and best practice call for a PRV to reduce pressure and protect pipes, fixtures, and water heaters from damage.
Typically 50–80 PSI at the fixture. Code often limits maximum pressure; we set the PRV to a safe range and verify. We will explain the set point when we install.
When a PRV is installed, a closed system can be created and thermal expansion may require an expansion tank. We assess and install or verify the expansion tank when required by code.
