Years of Canadian freeze-thaw cycling and UV exposure can warp the moulded plastic or crack the clamp channel, leading to leaks around the lid even with a fresh O-ring installed. Replacing the complete assembly resolves lid-related leaks that persist after O-ring replacement alone.\u003c\/p\u003e \u003ctable\u003e \u003ctr\u003e \u003cth\u003eCompatible With\u003c\/th\u003e \u003ctd\u003ePondMax PF750 Pressure Filter\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eIncludes\u003c\/th\u003e \u003ctd\u003eComplete lid housing with integrated seal surface\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMaterial\u003c\/th\u003e \u003ctd\u003eUV-stabilized moulded plastic\u003c\/td\u003e \u003c\/tr\u003e \u003c\/table\u003e \u003ch3\u003eHow to Use\u003c\/h3\u003e \u003cp\u003eDrain the filter fully and release the lid clamp before removing the old lid.
