How do I clean my top filling HammerHead?

Step by step instructions for cleaning a top filling Hammerhead.

Unscrew the bottom plug assembly (counterclockwise) to remove it from the pump casing. Remove remaining internal pump-assembly - grasp top of pump, wiggle side to side and twist while pulling out of pump casing. All parts are now removed from pump. Clean as necessary. Reverse the process to reassemble the pump, starting with STEP 4. Slide internal pump assembly into pump casing. The o-ring should slide into the casing. NOTE: the casing is universal - the pump can slide into either end. (See photo) Screw the bottom inlet assembly back into the pump casing and tighten. Remove the barbed fitting from the discharge check assembly. Remove the check ball. Clean the check ball, check seat & barbed fitting as necessary. Remove the discharge check assembly from the black wye fitting. Remove the inlet screen assembly from the black wye fitting. Remove the inlet check ball. Clean the check ball and seat as necessary. Reassemble the inlet and discharge check assemblies. Tip the pump over from top to bottom. You should hear the float sliding freely inside the body. Warning: The top fill inlet assembly (the wye) is a relatively delicate component in terms of assembly of the fittings. Over tightening of the check assembly or other fittings could result in leaks or even cause the wye to split at the parting line.
