UltraZap multi-port valves are the control valves for sand filters: one handle switches between filter, backwash and rinse modes without taking the filter off the plumbing.

The matching top assembly is a direct fit when the valve top or handle is worn. Both parts suit sand-filter setups on garden ponds, koi and fish tanks, aquariums and swimming pools, where backwashing is how you clean the sand bed.

Good to know:
– Two options: multi-port valve, or top assembly only
– Filter, backwash and rinse modes from one handle
– Change modes without disconnecting the plumbing
– Top assembly replaces a worn valve top or handle
