Fleck 5600 Backwashing Filter

Note: The 5600 filter control is standard on all units on this page. It's a simple, straightforward device that requires 110 volt electricity. Setup is a snap: just set the time of day and pull out the pins on "skipper wheel" on the right for the days you want the filter to backwash. The valve will take care of things from there.

Pure Water Products does basic water testing at no charge.

Our 5600 Filter Series

This series of softener-sized backwashing filters addresses the most common problems of city and rural customers. Automatic backwashing filters are simple, straightforward devices with few moving parts. They need an electrical supply, but their electrical consumption is negligible — about the same as the timer on your kitchen range. (We can supply a non-electrical, manual backwash version of these filters if needed. Details are at the bottom of this page.)

Each of these filters consists of an advanced 10" x 54" Vortech mineral tank loaded with 1.5 cubic feet of filter medium. With the Vortech tank, no gravel underbase is needed, as is the case with conventional filter tanks. (The single exception is the calcite filter, which comes in a conventional-style tank, for which gravel is provided.)

Water enters the filter tank from the top via an electrically powered control valve, passes downward through the filtering medium to the bottom of the tank where it enters a riser tube that sends it out to your service line via the control valve. It's a simple device, and there isn't a lot that can go wrong. The control valve times the operation and backwashes the medium at intervals that you preset — for example, every fourth day or every sixth day — according to need. The backwashing process is done in the early morning hours when filtered water is least likely to be needed. Backwashing cleans the filter medium, fluffs it up, and restores the filter's capability.

All filters listed below are of the size described above (10" x 54" tank with 1.5 cubic feet of filter medium) and all use the reliable and durable Fleck 5600 control valve. (See picture at right.) The mineral tank is a tough, water-saving Vortech. Filter media are top industry brands by makers like Clack and Calgon. Some filter media last virtually forever, while others require periodic replacement. See media descriptions below for details.

Backwashing Filters

Note: The filters in the chart below are complete. They are equipped with a stainless steel bypass valve for easy connection to your plumbing. Each filter comes with flexible drain tubing and a funnel for easy loading of media. (Weight of the filter media makes pre-loading before shipping impractical.) The filter pack contains everything you need to install, plus easy-to-follow printed instructions and phone/email support if needed. The price also includes delivery anywhere in the Continental USA. Please inquire about shipment to other localities.

When you order, you'll be asked to choose between a connection to either 3/4" or 1" pipe. The price is the same, but you'll make your installation easier if you know your pipe size when you order. If you're installing on pipe larger than 1", you should probably consider a larger filter.

1.5 Foot Standard Carbon Filter. Contains 1.5 cubic feet of GAC (granular activated carbon). It provides excellent dechlorination and aesthetic improvement and is the most frequently chosen unit for “whole house filters” to treat chlorinated city water. Removes chemicals. Removes small amounts of sulfide. Is a good iron remover but only if used behind an oxidizer like air or chlorine.

1.5 Foot Centaur Catalytic Carbon Filter. Centaur is a specially prepared carbon made by the Calgon corporation for the removal of hydrogen sulfide and iron from well water or chloramines from municipal tap water. Makes a great “whole house” filter for general city water use, especially where chloramines are used, nd works well with oxidizers like air and chlorine for sulfide or iron removal. This filter costs more than the standard GAC filter above because catalytic carbon is quite expensive.

1.5 Cubic Foot GAC Filter, Green, Water Saving Version. This is the same filter as BW006, but it has the “low water” 5600 control with shortened backwash and rinse cycles. It requires only about half as much backwash/rinse water as compared with the standard 5600 control. Recommended for clean city water applications only.

1.5 Cubic Foot Centaur Catalytic Carbon Filter, Green, Water Saving Version. This is the same filter as BW003, but it has the “low water” 5600 control with shortened backwash and rinse cycles. It requires only about half as much backwash/rinse water as compared with the standard 5600 control. Recommended for clean city water applications only.

1.5 Foot Filter Ag Filter. Filter Ag is a general purpose medium that lasts almost forever. It makes an excellent sediment filter and will remove iron from water that has been properly treated with chlorination or aeration. It is light and backwashes easily. There is very little pressure drop using Filter Ag. Filtration is down to about 20 microns. This is an inexpensive filter because Filter Ag is inexpensive.

1.5 Foot Birm Filter. Birm is an especially prepared iron removal medium. It can remove small amounts of iron without pre-treatment, but works best following aeration. Because birm has the ability to oxidize iron, it can be used without pre-treatment of the water if iron levels are small. The pH must be 6.8 or above for birm to work properly. Birm should not be used on chlorinated systems, but it works well after aeration. Birm is also effective at manganese removal.

10" X 54" Calcite Filter. This is a neutralizing filter designed to raise the pH of acidic water. It uses the same 5600 valve, but has a slightly different tank with a dome hole that permits the addition of calcite without removing the filter valve.

The filter includes 2 cu. feet of calcite—enough for the initial filter load plus a 50 lb. box to spare. Calcite dissolves slowly as the filter operates, so it has to be replenished occasionally.

(Calcite is inexpensive but heavy, so shipping is a factor. Our price includes shipping of 200 lbs. of calcite, so delivery of this item is often by truck.)

10" X 54" Multi-Media Filter. Multi-Media is a traditional favorite for sediment removal. It consists of natural filtration materials like sand, garnet, gravel and anthracite arranged in layers to achieve sediment filtration down into the 10 to 20 micron range. The standard multi-media unit sold here uses 45 lbs. garnet, 35 lbs. sand, and 25 lbs. anthracite. If you want to put alternate media into the mix, let us know.

(The price is higher than that of some filters because of the weight of the media. Remember that our prices include shipping.)

10" x 54" ChemSorb Filter. ChemSorb™ is one of the newer sediment filter media on the market. Its main ingredient is high purity natural zeolite. It has the advantages of high flow rate vs. low backwash requirement. The 10" filter requires about 7 gallons-per-minute backwash capacity, but supports a service rate of 7 to 10 gallons per minute. It has a nominal filtration rating of 5 microns—better than Filter Ag or Multi-Media.

Yokes and Bypasses

The Fleck 5600 control valve cannot be installed without either a yoke or a bypass valve. The filters on this page come standard with a bypass valve. The bypass is an especially helpful feature. If for some reason you prefer the yoke, let us know when you order and we will refund you the price difference.

Yoke and Bypass explanation.

Funnels and Drain Lines

Filters we sell come with a media funnel (a funnel especially designed for loading media into filter and softener tanks) and 50 ft. of flexible drain tubing. There is no charge.

If you wish to purchase drain tubing or a softener funnel separately, visit our backwashing filter accessories catalog.

Manual Control Filter

If you want the filters above with a Fleck 2510 manual backwashing valve rather than the 5600 timer valve, simply tell us that in the comments section of the shopping cart and we'll deduct $60 from the price shown. The manual filter needs no electrical connection, but you'll have to manually initiate and turn off the backwash and rinse functions. (Note on ordering: the shopping cart will not subtract the $60 price adjustment, but we'll refund it before your order is shipped.)
