Using chemicals isn’t our favorite thing, but sometimes chlorination seems the best answer to well problems. Chlorine, of course, is the municipal water supplier’s standard approach to disinfection, and it performs the same function for well owners.

In addition, chlorine is a powerful and effective oxidizer that can be used to treat common well problems like iron and hydrogen sulfide. Typical well treatment involves chlorinating the water then following with filtration. The most commonly used filter medium is carbon, which not only removes the chlorine and makes the water more healthful and aesthetically pleasing, but also filters out oxidized iron, sulfur, iron bacteria, and particulate matter.

Dry pellet chlorinators offer several advantages over liquid chlorine-feed systems. They’re very easy to install, they are trouble-free, and they usually require no retention tank. They free you of the messy and unpleasant job of chlorine solution preparation. You are assured consistent chlorine delivery without concerns for evaporation or freezing. Chlorine pellets are dry, clean, and concentrated. A single 3.5 pound container will usually treat the water supply of a family of four for several months. Since they do the job inside the well where the problem is, the whole well and pump system stay clean and problem-free.

We offer the best dry-pellet dispenser on the market, the very popular Well Pro© system made by the Autotrol Corporation, one of the most respected names in water treatment and maker of the famous Autotrol filter and softener control valves. The Well Pro system comes in four models—all priced identically. You need to know only if your well pump uses 115 volts or 220 volts and to decide if you want the “interrupter” feature which shuts the Well Pro system down any time the well pump runs over fifteen minutes. This is a safety feature to avoid over chlorination, and it is recommended in most cases.

Operation of the chlorinator is simple. The unit is wired into your well pump’s electrical supply so that it runs while the pump runs and shuts off when the pump shuts off. As it runs, it drops one to three (adjustable) small chlorine pellets into the well per minute. The highly concentrated pellets sink into the well and dissolve slowly, killing bacteria and cleaning up iron and sulfide problems. When the water leaves the well, it passes through a backwashing filter (usually carbon) for removal of oxidized particles and final polish. If a carbon filter is used, the chlorine will also be removed, so that the water that enters the home will be very clean and chlorine-free.

Pictured below is a typical home installation. You may or may not need a water softener (or a retention tank, for that matter), but you do need a carbon post-filter with a dry pellet system. The carbon filter captures the oxidized contaminants and removes the chlorine from the water before it enters the home. The filter can be by-passed occasionally to allow chlorinated water into the home to clean out appliances and water lines. (Diagram is not drawn to scale)

Explanation : UPS will ship only full cases of pellets and charges a significant hazardous materials surcharge. (Shipping costs us about $45 for a full case of pellets, so keep that in mind if you’re comparing prices.) We regret that stricter shipping regulations no longer permit us to ship single bottles of pellets.

Note : Chlorine Pellets are not returnable due to hazardous shipping rules. WellPro dry pellet chlorinators are returnable under our standard return policy, but pellets can’t be returned.

Note : We also sell liquid chlorine feeder equipment on this site. Please go here for information.
