Overview

Twin-Vessel Filter + Softener, Manual

The same two-stage treatment as the automatic twin system, run entirely by hand. The filter vessel is backwashed and rinsed from its manual valve when the pressure drop rises; the softener is regenerated from its own manual valve with brine from the shared tank. Robust, simple to service and independent of the power supply.

Stage 1: pressure sand filter with graded gravel, coarse and fine sand
Stage 2: ion-exchange softener with INDION 220 Na resin
Two Runxin manual multiport valves, no electricity
Identical Pentair FRP vessels
Simple routine we set up from your water 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.
