Hayward SX244K Sand Filter Top Closure Dome - For S244SX
What This Part Is Used For
The Hayward SX244K is the top closure dome used on the Hayward S244SX sand filter as listed. 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.
Why This Part Matters
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.
