Brine Valve, 1700, 2.0 GPM

This Fleck Brine Valve is the 1700-style, 2.0 GPM assembly compatible with Fleck 2750, 2850, and 2900S controls. The brine valve sits in the salt tank and governs the two brine-side functions of regeneration: drawing saturated brine into the control valve and metering the refill of water that prepares the next batch of brine. On the larger Fleck controls it serves, dependable brine handling is central to keeping the resin fully recharged.

Compatibility and function

• 1700-series brine valve, 2.0 GPM rating
• Compatible with Fleck 2750, 2850, and 2900S controls
• Manages brine draw and refill metering during regeneration
• Genuine Pentair Fleck replacement assembly
• Includes the float-actuated safety and shutoff function for the salt tank
• Sized for higher-demand residential and light-commercial systems

These mid- to large-capacity Fleck controls are common on higher-demand residential and light-commercial systems, where dependable brine handling is essential to keeping the resin bed fully recharged cycle after cycle. The 2.0 GPM rating sets the refill flow, working with the controller's timed refill to determine how much water enters the salt tank and therefore how much brine is prepared for the next regeneration.

Just as importantly, the valve's float mechanism provides a built-in safety function, shutting off refill at the proper level to help prevent overfilling and flooding of the salt tank, a feature that protects both the equipment and the surrounding area. A brine valve that is working correctly is something most owners never think about; one that is failing quickly makes itself known.

Replace the brine valve when you see symptoms such as inconsistent salt usage, a brine tank that overfills or won't draw down, weak regeneration, or salty water after a cycle. When installing, set the float and air-check height according to the system's specifications and confirm smooth, unobstructed float travel. Always place the system in bypass and relieve pressure before working in the brine tank. A correctly matched 2.0 GPM brine valve restores accurate, efficient regeneration to your 2750, 2850, or 2900S softener. Setting the float height carefully and verifying smooth operation on the first regeneration after installation ensures the brine valve draws and refills exactly as intended, keeping the system efficient and the salt tank safe from overfill.
