PRV Replacement and High Water Pressure Repair in Ladera Heights, CA

Service: Water Pressure Regulator Replacement | Location: Ladera Heights, CA | Result: Completed same day

The Problem

A Ladera Heights homeowner on Centinela Avenue contacted 24/7 Rooter Service after experiencing multiple unexplained plumbing failures over two years — a washing machine supply hose burst, two toilet fill valves failed within months of being replaced, and a pinhole leak developed in a copper supply line. The homeowner had no idea these were all connected to the same root cause.

What We Found

We tested the water pressure at the hose bib during the service call. The gauge read 135 PSI — nearly double the safe residential maximum of 80 PSI. The existing pressure reducing valve was original to the home, over 20 years old, and had completely failed to regulate pressure. Ladera Heights hillside properties commonly experience high supply pressure due to elevation, making PRV service a frequent need in this neighborhood.

What We Did

We shut off the main water supply, removed the failed PRV, and installed a new brass pressure reducing valve set to 65 PSI. We also installed a thermal expansion tank on the water heater as required by code for closed plumbing systems. After installation we tested pressure at multiple fixtures throughout the home to confirm consistent regulation. The entire job was completed in two hours.

Result

Water pressure throughout the home dropped from 135 PSI to a consistent 65 PSI at all fixtures. The homeowner was shown before-and-after pressure readings. We advised that the existing copper supply lines should be monitored for additional pinhole leaks given the years of high pressure damage, and recommended a follow-up inspection in 12 months.
