How It Works

The FL62103-59 valve functions as a critical control point within your water softener’s regeneration cycle. It regulates the flow of water during softening, backwash, and recharge phases to ensure the system effectively removes hardness minerals. Operating on a 24v power supply, it interfaces with the NXT2 or XT control heads to synchronize valve movements precisely with the programmed cycles.

This valve’s lower PH design allows it to handle specific pressure and flow requirements typical of Fleck 3900 systems, maintaining smooth operation and preventing leaks or flow disruptions that could compromise water quality or system integrity.

What to Expect

After installation, you will notice your water softener operates with improved consistency and fewer interruptions in service. The valve’s precise control means regeneration cycles run optimally, so you enjoy soft water without unexpected hardness fluctuations. Over the first few weeks, performance will stabilize as the valve integrates with your system’s control head.

Long-term, expect dependable operation with minimal maintenance. The valve’s durable components resist corrosion and wear, helping extend the lifespan of your water treatment system and reducing the frequency of repairs or replacements.
