How A Bladder Pump Works
Refill Cycle
During the refill cycle, with no air pressure holding it
down, the water pressure pushes the bottom check
ball up, allowing the water to reenter the bladder
chamber. The bladder expands as it refills with water.
Simultaneously, the top check ball is forced down
and seals because of the force of the water pressure
above it from the water in the discharge tubing, this
prevents the water in the discharge tube from
reentering the bladder chamber.
Caution:
A Well Wizard® pump bladder can be
punctured if you pump sand. So be sure to use an inlet
screen in wells with high sand and sediment content,
or when the inlet of the pump is placed within 2 feet of
the bottom of the well. Remember, the Well Wizard
10-year warranty is void if you do not use an inlet
screen.
