FAQ’s
Why does my water look clear yet stain my fixtures a rusty orange color?
There are different types of iron found in water that cause different problems. Ferrous iron is clear iron that may have an off taste that will cause rust staining when it has an opportunity to come into contact with oxygen. This type of iron can sometimes be filtered through a water softener. If the iron is above a certain level, a softener will not be able to accommodate excessive levels of iron. This level is determined through a water analysis.
Another type of iron found in this area is ferric iron. This type of iron has an orange appearance and sometimes may also be filtered through a water softener if the iron level is not excessive.
A third type of iron staining can result from an iron reducing bacteria. Although not a health concern, iron bacteria can result in staining and mechanical problems with several appliances. This type of contaminant must be eliminated with chlorine or other bactericidal water conditioning technologies.
When dealing with a higher level of iron, an iron filter is required. This piece of equipment is installed prior to the water softener and works independently of the water softener. Guthrie & Frey Water Conditioning installs an iron filter called the Iron Curtain. It is designed to treat the water for both iron and odor.
Why does my water have a terrible odor, similar to rotten eggs?
There are two forms of sulfurs that can appear in water: hydrogen sulfide gas, and sulfate salt. Hydrogen sulfide can have a rotten egg smell & taste. Hydrogen sulfide can also be responsible for tarnished silverware and yellow or black stains on kitchen or bathroom fixtures. Hydrogen sulfide can also cause pipe corrosion.
Hydrogen sulfide is corrected by an oxidizing method that will remove contaminants from water through a chemical reaction. Aerating is the process of exposing water to pure oxygen. The oxidation process is designed to convert the hydrogen sulfide gas to a solid that can be mechanically removed.
The “Rotten Egg” odor can also be the result of sulfur reducing bacteria. (SRB’s) Although they don’t present a health risk, SRB’s can result in odor, staining, & mechanical problems throughout the plumbing and related appliances. The most common way to treat for SRB’s is with extended exposure to bactericidal levels of chlorine. Particularly different cases may require pH adjustments and contact times in excess of 48 hours.
