OPERATION
MAINTENANCE
Operation of the P-164/264 Diamond Series Quarter Turn Wall Hydrant is a simple process. Water flows through the
hydrant after turning the handle (or operating key for the P-264 style) counter-clockwise to the “on” position. Turn off the
hydrant by turning the handle clockwise to the “off” position.
The hydrant will drain for a few moments. If the dripping persists after a few moments, tighten the handle slightly until the
dripping stops. Be careful not to overtighten the hydrant.
The P-164/264 incorporates an integral atmospheric anti-siphon vacuum breaker that, in the rare occurrence of a back
siphonage, opens to the atmosphere preventing contamination of the water supply.
As well as an atmospheric vacuum breaker, the P-164/264 incorporates a backflow preventer that operates as a check valve
in the rare case that water is forced backwards into the valve. The backflow preventer has been tested to 125 PSI pressure.
ALWAYS REMOVE HOSE DURING FREEZING TEMPERATURES
