Before you start
Confirm casing & components
Verify 5-9/16" actual casing O.D., correct WCP model, intact aluminum top, PVC base, four bolts/nuts and stainless steel screened vent.
Make the work area safe
Turn off and verify pump power. Keep the well opening clean and protected. Prepare approved conduit fittings and hand tools.
5 simple steps
Shut off power & protect the well
Switch off and verify pump power. Keep dirt, loose hardware and tools out of the opening. Do not disturb equipment supporting the pump.
Check the casing rim
Confirm the correct casing size. Clean away dirt, rust and burrs; check that the casing rim is sound and level.
Position the WCP cap
Inspect the PVC base and stainless steel vent screen. Set the cap squarely on the casing and verify that the base seats properly.
Secure the four bolts
Start all bolts by hand. Tighten evenly in stages until secure; do not distort the PVC base or overtighten.
Connect conduit & inspect
Have a qualified person install the approved electrical conduit connection. Keep the screened vent open; check for gaps or movement.
DangerDisconnect and verify pump power before work. Never handle live wiring or disturb components supporting the pump.
ImportantKeep the stainless steel screened vent clear. Follow well/electrical codes; confirm WCP mounting details and bolt-tightening requirements.
