What This Valve Does

• Filter position: Sends water through the sand filter for normal filtration.
• Backwash position: Reverses/redirects flow to flush debris out of the sand bed and out to waste.

When to Replace

• Water leaks from the valve body, shaft area, or around glued connections (after ruling out plumbing issues).
• The handle is difficult to move, sticks, or will not fully seat in either position.
• Backwashing no longer restores normal flow, or the valve will not hold position and allows bypass/mixing between modes.
• Cracks, warping, or UV damage on the valve body.

Included

• Complete slide valve assembly with 2" socket (slip) ports

Installation and Maintenance Tips

• Turn power off at the breaker, shut valves, and relieve all pressure at the filter air-relief (if equipped) before servicing.
• Confirm you have 2" plumbing and adequate straight pipe length for solvent-weld (slip) connections.
• After installation, allow solvent cement cure time per the cement manufacturer instructions before restarting the system.
• Operate the valve only with the pump off to prevent internal damage and to reduce the chance of water hammer.
• If the handle becomes stiff, inspect and service the piston O-rings (and lubricate O-rings with a pool-safe silicone lubricant).
• Winterizing: drain the filter system and leave the valve in a position recommended for your climate to reduce freeze damage risk.
