Water Pressure Regulators & Thermal Expansion Tanks in Northridge, CA

The Trouble With Inconsistent Water Pressure

Managing pressure correctly is not optional. It is a fundamental part of maintaining a reliable plumbing system.

Water pressure that is too high places continuous stress on pipes, valves, fixtures, and water heaters. Pressure that is too low prevents fixtures and appliances from operating as designed.

If your pressure has not been checked within the past year, scheduling an inspection now can extend the life of your fixtures and reduce long-term repair costs.

How Water Pressure Regulation Protects Your Plumbing System

Water pressure regulators are designed to reduce incoming municipal pressure to safe operating levels.

These mechanical devices are typically installed on the cold water main and adjusted to meet the property's specific demands. In many areas of Southern California, municipal water pressure can exceed safe limits before it ever enters a home or commercial building.

California plumbing code requires a pressure-reducing device when supply pressure exceeds 80 PSI. Most plumbing fixtures and appliances are designed to operate below the 80 PSI threshold, with optimal performance typically occurring between 50 and 55 PSI. Exceeding these limits can lead to leaks, premature wear, and voided manufacturer warranties on fixtures and appliances.

Why Thermal Expansion Tanks Are Now Part of the Solution

Modern plumbing systems often require both a pressure regulator and a thermal expansion tank. As heated water expands within closed systems, pressure builds rapidly inside the system without a place for that expansion to go.

In areas throughout the San Fernando Valley where higher water pressure is common, the combination of a properly adjusted regulator and a correctly sized expansion tank plays a critical role in preventing pressure-related failures.

Why Routine Pressure Evaluations Matter

Unchecked water pressure can lead to denied insurance claims and costly repairs. If a pipe fails and an inspection determines excessive pressure was the cause, insurance coverage may be impacted.

For that reason, water pressure should be evaluated at least once per year by a qualified plumber or monitored by the property owner.
