Pressure Relief

Piston Pumps

Gage For either shallow or deep-well piston pumps, a relief valve is used to relieve excess pressure in case something causes the automatic pressure switch to fail. Instead of pressure continuing to build to where the motor, pump, or tank is damaged, the relief valve opens. Enough water escapes to keep the pressure within safe limits.

Centrifugal or Jet Pumps

These pumps seldom have relief valves. As pressure on them builds, the pumping capacity decreases. The pressure finally climbs high enough that all pump action stops. That point is usually still low enough to prevent any damage to the storage tank and pump.
