Water Pressure

Font Size: + -

High water pressure is required for fire hydrants and for water to work against gravity and reach the top levels in multi-story buildings.  Supplied water pressure varies in different parts of Jurupa Valley and Eastvale depending upon location and demand.  An average residential JCSD customer can expect to get water delivered to their meters at a static pressure of 40 to 150 pounds per square inch (psi).

Once the water gets to your house, if the pressure is greater than 80 psi, you are required to have and maintain a water pressure regulator device on your property.  Regulators are the responsibility of the property owner.

What is a Pressure Regulator?pressure reducer

A water pressure regulator, also named a pressure-reducing valve (PRV), is a plumbing fixture that reduces the water pressure coming from the main water line into the house. This valve brings down the incoming pressure to a safe level before the water reaches any plumbing inside the home.  It provides protection to your home from unexpected water pressure surges that can occur during construction or normal water system maintenance.

Many homes are equipped with a pressure regulator. Pressure regulators are bell shaped devices that are usually located on the inlet pipe next to your hose bib and house valve. 

While you cannot increase your water pressure with a pressure regulator, you can adjust them to reduce your water pressure.

How to Check Your Water Pressure

a water gauge reading 55psi is connected to an outdoor hose bib, ideal house pressure is between 40psi and 60psi

First, turn off all running water.  Attach a water pressure gauge (can be purchased from a hardware store for about 10-20 dollars) to a faucet or hose bib and turn the water on.  Take the reading.  Most homeowners set their pressure at approximately 50 psi.  Setting your water pressure at 60psi or lower will help conserve water and extend the life of plumbing fixtures.

  • Less than 40psi: Low Water Pressure

    • Troubleshoot or contact our Customer Service for assistance

  • 40psi – 60psi: Acceptable

    • Most homeowners set their pressure at 50 psi

  • More than 80psi: High Water Pressure

    • Can cause plumbing leaks, worn seals, and damage fixtures
