Compact, convenient home well water treatment. Well PRO makes sink-staining iron and manganese, pump-clogging bacteria and the rotten egg smell of hydrogen sulfide a thing of the past.

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.

Additional Notes

One 3.5 lb. bottle of pellets should last approximately 4 weeks under normal operating conditions.
