Sand pump systems are popular for their superior filtration quality. Unfortunately, only Summer Waves RX ground pumps were compatible with the Polygroup sand filter systems. No longer! Our SFX Sand Pump Adapter Kit will convert your SFX1000 or SFX1500 into a sand pump compatible unit in just a few easy steps. Simply remove the pump motor at the bottom of your SFX system, apply plumber's tape to the inside seal gasket of the adapter, and screw on the adapter to the bottom of your SFX canister. Voila! Your SFX Summer Waves pool can now operate with a sand filter pump by Polygroup! This adapter will also allow you to use a traditional RX ground pump with your pool.
