YOU SHOULD INSPECT A PRV EVERY 1 AND 5 YEARS
Pressure Reducing Valve (PRV)
A yearly test is done by doing a partial flow test, which needs to be done by flowing enough water to move the valve from its seat. A 5 year test is done by conducting a flow test on each hose valve and comparing them to the previous result, by using an upstream and downstream valve simultaneously.

A PRV takes higher pressure and reduces it down to a lower pressure. It’s usually seen with fire pumps that are connected to floor sectionals or hose valves.

Frequently Asked Questions
How do you know if your PRV is going bad?
Leaks, fluctuating water pressure, vibrating, allowing more than the set pressure, no pressure at valve.
What happens if your PRV doesn’t work?
Your pressure can be too high, too low, or non-existent, causing the sprinkler system to have a catastrophic failure or not operate as it was designed.
