Fleck Injector, #1 7000, 5810/12 Valve

Keep brine draw strong on your Fleck softener with this genuine Pentair Fleck Injector, size #1, for 7000-series and 5810/5812 valves. The injector is the heart of the regeneration brine draw: it uses a venturi to convert flowing water into suction that pulls salt brine from the tank and carries it through the resin bed. It is part of the Fleck Injector service family and is matched to the 5812 platform.

The #1 injector sits a step up from the smallest #000 and #00 sizes, making it appropriate for tanks and flow rates that call for slightly greater draw capacity. As water rushes through the narrow injector throat it accelerates and loses pressure, generating the vacuum on the brine line that lifts concentrated salt solution into the media. There, sodium ions exchange with the hardness ions held on the resin, recharging the bed for the next service run. Matching injector size to your tank diameter is essential for a clean, complete regeneration.

• Generates venturi suction for consistent brine draw
• Sized for mid-range tank diameters and flow rates
• Replaces scaled or clogged injectors that stall regeneration
• Precision component for dependable softener performance
• Compact and quick to service

A Common Service Item

Because the injector throat is so narrow, sediment, iron, or salt-bridging debris can restrict it and cause weak or failed brine draw, which shows up as a return of hard water even though the valve still runs its cycle. Cleaning or replacing the injector typically restores normal operation right away. Many service calls that look like a major valve problem turn out to be nothing more than a fouled injector. Verify the #1 size suits your system before installing, clean the injector screen at the same time so debris doesn't immediately re-clog the new part, and depressurize the valve before removing the injector cap. With the correct injector in place, your softener will draw a full brine charge and deliver consistently soft water. Keeping the correct injector size on the shelf for your specific system means a simple fouling issue is never more than a quick swap away from being resolved, avoiding extended stretches without soft water.
