**Carvin 22.5 in Sand Filter - 94089220
- Upper distribution system integrated into the dial valve and engineered to direct water evenly across the entire surface of the sand - up to 25gpm/sq.ft. (61 m3/h/m2) without sand migration or channeling. The new 'egg-shaped' body maximizes flow.
- 7-way dial valve with "sight glass" automatic air relief, and pressure gauge.
- Non-Corrosive resin clamp for simple installation and service of dial valve and filter components.
- Under drain with "side-slotted" laterals draws water evenly across the full diameter of the sand bed for higher flows, better filtration, longer cycles and more efficient backwashing.
- Features heavy-duty, freeze resistant hub and easy-service "Snap-fit" laterals.
- Deep, high-capacity sand bed carries more debris and extends filter cycles.
- Blow-molded tank is corrosion-resistant and UV-resistant.
- Bottom drain for winterizing and draining.
- Hose and hardware included.
