AstralPool - Colusa Pump Pre-filter Cover - 4405010789

AstralPool – Colusa Pump Pre-filter Cover

This is the genuine AstralPool replacement pre-filter cover for the Colusa pump (parent SKU 70579). Positioned at part number 2 in the official Fluidra exploded view, this cover seals the pre-filter housing at the front of the pump, keeping the water-flow path closed while allowing easy access to the pre-filter basket for routine inspection and cleaning.

Compatibility

This cover is designed exclusively for the AstralPool Colusa pump range (parent SKU 70579). Always cross-reference the exploded view position and parent SKU before ordering, as pre-filter covers vary between AstralPool pump families and are not interchangeable.

Why Genuine Matters

As an official AstralPool OEM part, this cover is manufactured to the exact tolerances of the original, ensuring a leak-free seal against the pre-filter housing. Aftermarket alternatives may differ in thread pitch, wall thickness or material grade, increasing the risk of water ingress, pressure loss or premature cracking.

Installation

Replacement is straightforward: isolate the pump, drain residual pressure, unscrew the existing cover, inspect the mating face and associated gasket or O-ring for wear, then fit the new cover by hand before tightening to the manufacturer’s specified torque. We recommend replacing the cover seal at the same time to guarantee a watertight result.
