How do you remove the lid on a Hayward pool filter? For a cartridge filter, simply depress the latches on the top of the filter tank. For DE and sand filters, use a wrench to loosen and remove the bolts securing the lid in place. All Hayward filters are equipped with a locking ring. Use a screwdriver to unscrew the locking ring.
