Fleck Cam, Rapid Rinse

Keep your Fleck control valve cycling on schedule with the genuine Pentair Fleck Cam, Rapid Rinse. The cam is the timing element that the valve's drive system rotates to advance through each stage of the regeneration sequence. In a mechanically timed Fleck head, the shape of the cam's lobes determines exactly when each microswitch trips and how long the piston dwells in a given position. The rapid rinse cam specifically governs the fast-rinse step that flushes the resin bed after brine has been drawn.

The Role of the Rapid Rinse Step

During regeneration, a water softener or filter pushes a high flow of water down through the media to settle the resin bed, rinse away residual brine, and prepare the resin for the next service run. If this step is too short, salty water and leftover brine remain in the tank; if it is mistimed, the bed may not be properly conditioned. The rapid rinse cam ensures this stage opens and closes at precisely the right point in the cycle, so the bed is rinsed thoroughly without wasting water or salt.

• Genuine Pentair Fleck replacement cam
• Controls the rapid rinse stage of the regeneration cycle
• Direct-fit timing component for compatible Fleck valves
• Restores accurate cycle sequencing in aging control heads
• Helps prevent salty water and incomplete rinses
• Simple, low-cost service part for routine maintenance

If your softener has started producing salty-tasting water, skipping the rinse stage, or otherwise running through its cycle out of sequence, a worn, cracked, or chipped cam is a common culprit. Plastic cams can wear at the lobe edges over thousands of cycles, gradually throwing off the timing the valve depends on. Swapping in a fresh Rapid Rinse cam is a quick, inexpensive fix that brings the valve's timing back to specification. This part is a popular service item for installers maintaining residential and light-commercial Fleck systems across the country. Always disconnect power and follow the documented timing procedure when reassembling so the cam indexes correctly to the valve. Because cams are inexpensive relative to the cost of a service call or a return of hard water, many homeowners and technicians keep the common timing cams on the shelf so a worn part never sidelines the system for long.
