as opposed to a liquid chlorine bleach injection system?
A. A pellet feeder, which drops small chlorine pellets down the well, every time the well pump runs, can be a good solution if you have no holding tank or retention tank, which is usually required for liquid chlorine injection. Pellet feeders can be ineffective if your well has wire protectors, or other obstructions that block the pellets from falling. If your well has a small access plug on the top of it, you can obtain some pellets and drop a few down the well to see if they fall into the water, which you can usually hear pretty clearly. Pellet feeders are often much more expensive to operate, as the pellets cost more than liquid sodium hypochlorite (bleach). Most of our clients using chlorination, use liquid sodium hypochlorite injection, but pellets are useful in some cases.
