The Sentry I simply works like a "gum ball machine" or "corn planter" and drops the precise amount of chlorine down the well and into the water supply. The amount of chlorine residual may be regulated to be LESS than that found in some city supplies.

Set exactly for your particular water problem.

Only 3 moving parts.

Entire process is patented!

Inexpensive operation and simple maintenance.

You can rest assured that your water problems are being solved and your pump, as well as all underground piping, are protected.

The SENTRY I system is a great oxidizer that treats iron, manganese, rotten egg smell and helps control iron bacteria problems. If coliform bacteria exists in your well please contact your state agency for regulating private wells or water supplies for further instructions.

If you live on a farm you'll enjoy even more added benefits. Many SENTRY I customers insist that the SENTRY I kills algae in cow tanks and reduces stress and medication costs with farm animals.

Maintenance costs decrease on water systems and nipples. It all adds up to more savings.

Used on wells for home, farm or business.

The SENTRY I stands guard protecting your water 24 hours a day-every day of the year.

Krudico's Calcium Hypochlorite 70% Dry Chlorinating Pellets can be used in this system as well as other chlorinators.
