Pressure Relief Valves

A pressure relief valve will allow you to drain the effluent line of liquid under pressure, usually installed on the bridge of hydrants.

Advantages

• Drains liquid so you don’t get covered in effluent when removing a hydrant bridge

Disadvantages

• No real disadvantages

Things to consider

The valves need to be installed in any low spot in the main line or if the hydrant is down hill from the irrigator.
