Overview

Manual Water Softener with Pre-filter

Everything about this softener is mechanical. When the set volume of soft water has been used, you turn the Runxin manual valve through its positions and the resin is backwashed, brined, rinsed and returned to service. We set up the schedule from your water report and show you the routine at installation. The 20-inch pre-filter keeps sand and silt out of the resin bed.

Runxin manual multiport valve: no power, no electronics
Built-in brine injector draws brine from the salt tank
20-inch sediment pre-filter protects the resin bed
Pentair FRP vessel with INDION 220 Na resin
Regeneration schedule set from your water test report

Good to know

Output per regeneration is quoted at 200 ppm hardness. Harder water means more frequent regeneration; your water report tells us exactly.

Softeners treat water for bathing, washing and appliances. For drinking water, pair with an RO purifier.
