PRVvalve

Water pressure within the Las Vegas Valley Water District water distribution system varies, depending on the elevation of your property in relation to the elevation of the reservoir that provides water service for your area.

Pressureregulator

PRVs will not increase water pressure to a property; however, they do serve as a critical component to decrease water pressure to your level of preference. Most plumbing professionals recommend a PRV setting between 35 and 60 psi.

If you're experiencing a decrease in water pressure at your property, the issue is typically within your plumbing system. The list below may help you identify the cause of the low pressure.

In accordance with Uniform Plumbing Codes, property owners and/or customers are responsible for installing and maintaining their own individual PRV devices whenever static water pressure exceeds 80 psi.

Sustained pressure that exceeds 80 psi can damage on-site plumbing systems and may affect your water fixtures. If the water pressure at your property is 80 psi or greater, a pressure reducing valve (PRV) will help decrease the water pressure.

PRVs should be installed on the customer’s side of the water meter and are usually located near the water heater, water softener or on the inlet water line between your home and the water meter.

If your home water system does not have a pressure reducing valve (PRV), you can purchase them from a licensed plumber, who also can install it. If a PRV already exists, it may just need an adjustment to decrease the pressure at the property.

The Water District cannot adjust the water pressure for specific properties; however, if you have concerns with high pressure or low pressure, there are some steps you can take that may help resolve the issue.

Peak water use and routine water system operations also can cause water pressure in the distribution system to fluctuate. Generally speaking, operating water pressure within our system can range from about 30 pounds per square inch (psi) to 100 psi.
