Installing the Bladder Pump Inlet Screen
Inlet screens extend the life of the pump, protect the bladder from damage by sand or other solids,
and help to prevent clogging and malfunction of the check valves in the pump.
Well Wizard bladder pumps equipped with an inlet screen carry a 10 year warranty on PTFE Teflon
bladder models and a 5 year warranty on Teflon-free bladder Zero models. Well Wizard pumps
installed without inlet screens are covered by a one year warranty.
Well Wizard 1000, 1200 and 1500 Series pumps have inlet screens that attach to an internal
female pipe thread in the pump inlet housing.
1100 Series plastic pumps (PVC or Teflon) use a slotted screen that attaches to external
threads on the pump inlet housing.
1300 Series pumps have an integral inlet screen that is fastened to the pump using set screws
that lock into a groove above the pump inlet.
Inlet Screen Installation for 1000 Series Pumps
1. Open the plastic wrapping and remove the screen.
2. Holding the pump inlet housing with an open end or adjustable wrench, thread the screen into the
female thread in the inlet housing.
NOTE:
Failure to hold the pump inlet with a wrench while installing the screen could result in
damage to the pump bladder assembly inside, which is not covered under the product warranty.
Inlet Screen Installation for 1100 Series Pumps
1. Open the plastic wrapping and remove the screen.
2. Thread the screen onto the external male thread on the pump inlet housing and tighten firmly by
hand only. Do not use tools to tighten the screen.
Inlet Screen Installation for 1200 and 1500 Series Pumps

Inlet Screen Installation for 1300 Series Pumps
