Fleck Backwashing Filters


Call us at (888) 382-3814

For a typical residential-sized filter, you may prefer to order from our Fleck 5600 Filter page.

It offers a simple one-size (10" X 56" mineral tank), one-valve (Fleck 5600) filter that includes shipping in the price.

We also offer control valves and mineral tanks separately, if you're looking for replacement parts.

Pure Water Products does basic water testing at no charge.

If you'd like, send us a sample.

The products shown on this page are filters, not water softeners. They do not require salt or chemicals. They all use an appropriately sized Fleck control valve. All have automatic timer control and all require a standard 115-volt electrical connection.

A backwashing filter is a simple device. It consists mainly of a large tank filled with a filtering agent, called a medium, that performs a specific change in water that passes through it. Depending upon the chosen medium, and sometimes the pretreatment, the filter may remove chlorine from city water, sediment particles from dirty well water, smelly hydrogen sulfide gas, iron, or other objectionable elements.

When the filter medium becomes saturated with the substance it is treating, a specially designed control valve reverses the flow of water and “backwashes” the filter medium to renew it. A more complete discussion of how backwashing filters work.

All filters on this page are complete. They include the filter valve specified, a steel bypass valve, a polyglass mineral tank, and a basket distributor with riser tube. Everything you need aside from filter media.

A complete filter consists of the basic backwashing filter, and the filter media (the stuff that goes in the filter and performs the magic). You'll need an item from both categories for a complete filter.

For increasing the pH of acidic water. Calcite dissolves as acidic water passes through and must be replaced as it dissolves. Unless it is used in an upflow filter, it must be backwashed.

Part # fm002

Corosex / FloMag

Corosex / FloMag
Corosex / FloMag
Like Calcite, Corosex (granular magnesium oxide — also marketed as FloMag) is used to raise the pH of acidic waters. It supports higher flow rates and gives a greater increase in pH, but it tends to “cement” in hard water and when it is mixed at a ratio higher than 50% with calcite.


Superb iron and hydrogen sulfide medium. Can be used independently or after any standard oxidizer. Chlorine tolerant, works well with aeration. Outlasts birm and greensand. A dense medium; approximately 6 gpm of service flow per cubic foot. Sold in 1/2 cubic foot boxes only. Go here for our series of Fleck 2510 filters with Filox.
