It seals the top opening of the filter tank and supports the top mount valve connection area. This part sits at the top of the filter on the equipment pad.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e If the dome is cracked, warped, or no longer sealing, the filter can leak under pressure and make backwashing and filtration messy and unreliable. A poor seal at the top can also introduce air and create priming issues depending on the plumbing layout. Replacing the correct dome restores a tight closure so the filter can operate normally. It is a common repair after freeze damage or overtightening during service.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManufacturer part number: SX244K\u003c\/li\u003e \u003cli\u003eSand filter top closure dome\u003c\/li\u003e \u003cli\u003eSpecified for Hayward S244SX sand filter\u003c\/li\u003e \u003cli\u003eSeals the top opening of the filter tank\u003c\/li\u003e \u003cli\u003eEquipment pad replacement part for top closure leaks\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Turn off the pump and fully relieve filter pressure before opening any top closure or clamp components.
