This Fleck 9000 Back Plate, part FL15131 from Pentair, is the structural mounting plate that anchors the timer and drive components on a Fleck 9000 twin-tank control valve. The back plate gives the motor, gearing, and switch hardware a rigid, properly aligned platform so the valve cycles accurately through service and regeneration. Because so many moving parts mount to it, the back plate's integrity directly affects how reliably the valve advances and switches between tanks.

Pentair discontinued this back plate in October 2024, but the part remains available within several service kits, including FL62103-70, FL62103-76, and FL62103-77. Those kits combine the back plate with the related drive and timing components technicians typically replace together when overhauling the upper section of a 9000 valve, ensuring a complete and properly matched repair.

• Available in kits FL62103-70, -76, and -77
• Restores rigid, factory-correct component positioning
• For Fleck 9000 twin-tank softener and filter systems
• Discontinued standalone; sourced through service kits

The Fleck 9000 is widely used for continuous, no-downtime soft-water service because its twin tanks alternate regeneration, so soft water remains available even while one tank recharges. Keeping the drive assembly solidly mounted is important to reliable switching between the two tanks, since the timing and indexing all depend on components staying in their designed positions.

A cracked, warped, or worn back plate can let the timing components drift out of alignment, causing mistimed cycles, failed tank switching, or incomplete regeneration. These faults can be difficult to chase if the underlying cause is a compromised mounting plate. Sourcing the back plate through one of the FL62103 service kits ensures every interacting part is fresh and matched, restoring the 9000 valve to the dependable, continuous operation it was designed to deliver.

For owners and installers maintaining 9000 twin-tank systems, sourcing the back plate through the appropriate FL62103 kit is the most reliable route now that the standalone part is discontinued. Because continuous soft-water service depends on the two tanks switching cleanly, restoring a solid, correctly aligned drive platform is well worth the effort. A properly rebuilt upper section returns the 9000 to the kind of uninterrupted, no-downtime performance that makes twin-tank systems a popular choice for higher-demand households.
