Discontinued-See Extended Desc.

This Fleck flat injector cap is a discontinued individual part for the Fleck 2510 control valve from Pentair, and it remains available within several service kits. The injector cap is a key piece of the brine-draw system, sealing and protecting the injector assembly that powers the regeneration cycle. Because the injector is so central to softening performance, keeping its cap in good, sealed condition directly affects how thoroughly and efficiently the system regenerates its resin.

During regeneration, the injector creates the venturi suction needed to draw brine from the tank and pull it through the resin bed to recharge the softening media. The flat cap seals the injector housing, helping maintain the precise pressure differential required for proper brine eduction. A cracked, warped, or missing cap can disrupt that pressure relationship, compromising brine draw and reducing the system's softening capacity, which often shows up as hardness returning to the treated water, so a sound, well-fitted cap is well worth installing.

Restoring Proper Brine Draw

If your 2510 valve is not drawing brine correctly during regeneration, the injector cap and screen are excellent components to inspect and refresh first. Order one of the listed kits to obtain the cap along with related injector parts and seals for a complete service rather than a partial repair. Confirm your valve model before purchasing to ensure a proper seal, and take the opportunity to clean the injector screen at the same time so the system regenerates fully and uses salt efficiently. Together these steps restore consistent, reliable brine draw and keep your treated water dependably soft. Addressing the injector cap, screen, and seals together as a set during service is the most reliable way to bring brine draw back to full strength and keep your 2510 softener regenerating thoroughly and economically for years. A properly sealed injector is one of the simplest things you can do to keep a softener running efficiently, and it often resolves brine-draw complaints in a single, straightforward visit.
