Screen shot 2013-11-27 at 1.47.04 PMThere are two basic problem water categories, according to the most referred Indianapolis plumber. The unhealthy and the unpleasant. Unhealthy water might contain nitrates, heavy metals (like lead and mercury), disease-causing bacteria, organic and inorganic compounds (arsenic, atrazine, benzene, and the like), and dissolved gases such as radon.

Unpleasant water might be high in iron, sulfur, manganese, sediments, non-hazardous bacteria, and so on. Municipal water is rarely unhealthy, but it may be unpleasant; private well water may be unhealthy, unpleasant, or both.

The first line of defense is usually a filter or series of filters. If you think you need a series of filters (to treat a variety of problems), you should get a professional Indianapolis plumber to help decide which filters to use and in which order.

Plumber Pro Tip of the Week

Tip #1 If your only problem is sediment, a single sediment filter will do. These in-line filters consist of a filter body, a reservoir, and a filter medium.

Tip #2 If tests reveal high levels of organic or inorganic contaminants, granular carbon filters may work. High-volume carbon filters are installed in supply lines; low-volume carbon filters serve a single fixture.

Tip #3 Reverse-osmosis units are reliable in dealing with nitrates and chemical contaminants. They should not be used with water high in dissolved minerals (hard water), and they can’t remove biological contaminants.

Tip #4 When water contains only biological contaminants, it’s a good choice to send it through a disinfection chamber. The chamber can be treated with chlorine, bromine, or iodine, but it might also be bombarded with ultraviolet light or saturated with ozone.

PLUMING TRADE SECRETS: One of the most effective ways to purify water is through distillation. In a distiller, water is heated until it steams, or vaporizes. The vapor rises into a cooling chamber, where it condenses back into liquid.
