Pump Repair:
NOTE: Flushing the pump fluid section with solvent will make it easier to clean and
rebuild.

to the floor, it will be damaged. (Even if it appears undamaged, it will contain dents and
scratches that will create problems.) Damaged balls must be replaced or the pump will
not work properly.
NOTE: When disassembling the Pro pump assembly, replace any O-Rings that you
expose.
