Air hammer Arrestors

The white chemical tank and injection pump is most likely a chlorinator... note the bottle of chlorox on top of it. There are a number of reasons to chlorinate beyond simple bacterial control. Most people I know in Northern NE (I am from Northern NH and Maine) have no interest in chlorinating because they believe in "City Water". I had a chlorinator in my home in NH for years. It was there to eliminate one problem and help with another. The one it helped with was to reduce the iron content of the water. Chlorinating "helps" reduce iron. The problem it eliminated was a problem called " bacterial iron" which has nothing to do with having "ionic" iron in your water.
Bacterial iron is a bacteria that lives in the interface between water and air. It forms a black sludge that sometimes can be found in the toilet tank, if present. If the chlorinator has been working, however, you will not find it there or anywhere above the chlorinator as it will eliminate the bacteria.
Also, keep in mind that a water softener when used with the correct salts also can reduce iron content in the water. It may be that the two were installed to help reduce a high ionic "iron" content in the water which by the way is somewhat prevelant in Northern NE. I had bacterial iron problem and a slightly high ionic iron content. The chlorinator did the trick.

Thanka Larry, good info.
I'll make sure my daugher gets someone to educated them in water conditioning and purification.
I know I could use more education on the subject.
