The pre-filter lid nut for InverPro pumps (part no. 1222010500007) is a connecting element that ensures a firm and watertight closure of the transparent pre-filter lid. A properly tightened nut is a prerequisite for leak-free operation of the pump’s suction circuit.
This variant of the nut differs from part 1222010500002 designed for IP pumps – before ordering, verify the exact model of your InverPro pump. The original part guarantees compatibility with the pre-filter body thread.
Replacing a worn or damaged nut is simple and does not require professional qualifications. For proper tightening, we recommend using the original pre-filter wrench, which is available as a separate accessory part.
