What is a Pressure Reducing Valve?

When it comes to water pressure in your home, too much actually is not good! Have you checked to make sure your Pressure Reducing Valve (PRV) is installed and working properly?

Pressure reducing valves are devices that work directly to slow down the pressure of water flowing from our (HCWA Water Distribution) System into your home. They typically are installed on your main water line going into your home, next to the shut-off valve at the street.

Why is a PRV critical for your home’s safety? Because every pipe, appliance, and fixture inside was built to withstand a certain level of water pressure, which runs between 60 to 80 PSI. In some areas, the HCWA’s water pressure coming into your home might be much higher than this.

Without a PRV, your shower heads, toilets, faucets, washer and dishwasher, water heater, and pipe joints can wear out and fail if they are regularly operating with higher than normal water pressure. Not only will you have to replace such hardware, but you may experience water leaks as well.

To make sure your PRV is installed and working properly, contact your local plumber. For more information, check out the Pressure Reducing Valve page under the Customer Care section of our website at
