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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>","protected":false},"excerpt":{"rendered":"
