- Fleck 2510 SXT air-injection control valve
- Mineral tank pre-loaded with iron-based arsenic-selective media, amount by size above
- Bypass valve
- Install and service manuals
System features
- Air injection. Oxygen converts arsenic III to arsenic V, the form the media holds best.
- Arsenic-selective media. Targets arsenic rather than everything in the water.
- Automatic backwash. The valve keeps the media bed clean on schedule.
- Bypass valve included. Service it without shutting off the house.
How it works
Water passes the air pocket at the top of the tank, which oxidizes arsenic III to arsenic V. The iron-based media then binds the arsenic and holds it. The valve backwashes on schedule to keep the bed clean and draws a fresh air charge.
Media benefits
- Iron-based arsenic-selective media: binds arsenic on contact and holds it in the tank.
- Works on both forms: with air injection ahead of it, the media handles arsenic III and arsenic V.
- No salt or chemicals: nothing to add and no brine tank.
What it does for your home
- Reduces arsenic in all the water in your home, not just one faucet
- One system for the whole house

Questions and answers
How do I know it is working?
Test your water after install and once a year. Arsenic has no taste or smell, so a lab test is the only way to know.
Do I need a drain?
Yes, for the backwash.
Does it come pre-built?
Yes. It ships pre-built, with the media loaded, the bypass valve included and install and service manuals in the box.
Is shipping free?
Yes. Shipping is free to the lower 48 states. Alaska and Hawaii are quote only.
Can I return it?
Yes. Every order has a 90-day return policy.

Fleck Arsenic System
A complete Fleck system — control head valve, tank and the right media — engineered to solve arsenic for good.
The Fleck system that solves it
This is a full Fleck system built on three parts that work together: a genuine Fleck 2510 SXT air-injection control valve on top of an air-injection oxidizing tank, filled with the media matched to your water. The valve draws a fresh air charge and backwashes on schedule, flushing the oxidized contaminants to drain automatically. 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 arsenic from your water
- Clear water with no orange, brown or black staining
- No rotten-egg or metallic smell
- Protects fixtures, laundry and appliances
- Self-cleaning — the system backwashes itself
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.
Prefer a different valve brand? The same arsenic 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

- Targets the specific contaminant — tannin, nitrate, arsenic, uranium or PFAS
- Leaves beneficial minerals in place
- High selective capacity for reliable reduction
- Regenerates for long service life
