Remove the valve cap, extract the old gasket, clean the seating surfaces, and seat the 40mm gasket evenly to prevent pinching. Reassemble, run a low-pressure test backwash, and check for leaks. This straightforward upgrade is ideal for pool technicians, service professionals, or DIY enthusiasts maintaining Waterco filtration setups.

Keep your pool water crystal clear and your filtration system dependable with the Spider Gasket for Multiport Valve 621460—the precise, durable seal you can trust across multiple valve families.
