Fleck Acidic / Low-pH Water System
A complete Fleck system — control head valve, tank and the right media — engineered to solve acidic / low-ph water for good.
The Fleck system that solves it
This is a full Fleck system built on three parts that work together: a genuine Fleck 5600 SXT backwashing control valve on top of an upflow calcite tank, filled with the media matched to your water. The valve backwashes the bed on schedule to keep flow strong and the media working — no cartridges to change. One consistent Fleck platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.
What it does for your home
- Removes acidic / low-ph water from your water
- Stops blue-green staining and pinhole pipe leaks
- Protects copper pipe, solder and fixtures
- Brings pH into a safe, non-corrosive range
- Self-backwashing calcite bed
Sized and matched to your water
Pick your home size above (1–3, 3–4 or 5–6 bathrooms) and we build it to your flow. Send a water test or your symptoms and we size it free. Ships free in the US with full install and service manuals. Need a matched multi-stage well package? See our same-brand Fleck well bundle.
Prefer a different valve brand? The same acidic / low-ph water solution is available in Fleck, Autotrol, C-Series, Pentek and Pentair — the media doing the work is the same.
The media inside — what actually cleans your water

- Dissolves slowly to raise low, acidic pH toward neutral
- Stops blue-green copper staining and pinhole pipe leaks
- Self-limiting — it won't overshoot pH
- Simple periodic top-up as it is consumed
