Pressure Relief Valve Placement:

To protect against surge, the system must have a pressure relief valve and for best results it should be placed at end of main 
suction line behind last hose drop.  This can help keep your overhead pipe flushed of debris by placing it at end of run.

Pressure Relief Valve
(Surge Protector)

REV 06/23/23

Two Pressure Relief 
Valves (example)
