The Well PRO
Dry Pellet

The first compact low-profile, dry pellet chlorinator for home well water needs. Foul-smelling, corrosive hydrogen sulfide. Sink-staining iron and manganese. Slime-causing, pump-clogging iron bacteria. These are unpleasant, and potentially costly, facts of life in many residential water wells.

Now, the Well PRO dry pellet chlorinator lets you control these problems at their source (in the well itself) with a compact, low-profile unit that blends comfortably into any home landscape. Designed specifically for residential use, the Well PRO chlorinator maintains your yard's aesthetics.

The Well PRO chlorinator is constructed of rugged, matte-black thermoplastic to resist corrosion from chlorine or the weather and mounts directly over your well for minimum intrusion on your landscape design.

Safe, simple, fast loading with prepackaged Well PRO pellets
The Well PRO chlorinator's highly concentrated dry chlorine pellets come in easy-to-store, easy-to-handle 3 1/2-pound containers that actually serve as the chlorine hopper. Each new container is simply screwed right into the chlorinator to replenish the chlorine supply, so you never need to handle any chemicals directly. And there are no fumes or spills to worry about. After opening the Well PRO chlorinator's protective cover, remove the power module and unscrew the cap from a full container of Well PRO pellets. Screw the power module directly onto the full pellet container. Insert the power module/pellet container assembly in the the Well PRO chlorinator protective housing and replace the cover.

Design simplicity ensures trouble-free performance

Designed specifically for outside installation, the Well PRO chlorinator's rugged weatherproof construction ensures reliable, uninterrupted operation in any weather. Easy to install and easy to service if necessary, the Well PRO chlorinator features precision-tooled, injection-molded components, few moving parts and a full array of performance features.
  • The plug-in power module is completely encapsulated in polyurethane foam to protect it from chlorine corrosion and requires no routine servicing or maintenance.
  • The rugged drive motor turns on and off according to water demand to maintain a consistent chlorine residual in the water.
  • The adjustable dosage rate makes the Well PRO chlorinator adaptable to a wide range of water problems and water usage characteristics.
  • System operation based on water usage. The Well PRO chlorinator is energized only when the well pump operates. Chlorine consumption is minimized and chlorination efficiency is maximized.
  • An automatic shutoff device prevents overchlorination if the well pump remains on for an extended period. 
  • To reduce pellet drop rate lower than system settings, see our pellet plate modification page.

In nearly all circumstances, it is advisable to consider doing a "shock treatment" on a well that has never been chlorinated or on a system you know needs disinfected. The Well Pro will do an excellent job of chlorinating at a "maintenance" level, but there is a better (and cheaper) way to go about performing a shock chlorination of your system than by using these dry chlorine pellets. As a courtesy, we have copied part of a university agricultural extension office's instructions on how to do a shock chlorination on your well and household plumbing using ordinary household bleach. Click HERE to read those detailed instructions. [We'll open that link in a separate browser window so you don't lose your place here.]


You can reference the "Installation, Operation and Maintenance Manual" in .pdf format.

Shipping turn-around time between order and delivery is right at one week to most points in the USA. If shipment includes chlorine pellets, which must ship as a "hazmat," that can cause some delay on the part of the carrier. We have no control over carrier (UPS) schedules.
