Overflow Valve with Pressure Switch
When the water flow rate is reduced by the
servopress valve in the hand-held spray gun,
the over-flow valve opens and some of the water
flows back to the intake side of the pump.
When the spray gun is closed completely, all the
water flows back to the intake side of the pump,
and the pressure switch switches off the pump.
When the hand-held spray gun is opened again,
the pressure switch switches the pump back on.
The overflow valve and the pressure switch are
factory-set and lead-sealed.
Adjustment by customer service only.
