Water quality varies from home to home, and there are many common water problems that can cause your water to have bad taste and smell, appear cloudy, damage equipment or plumbing, stain fixtures, or even affect your health.

From water softeners to acid neutralizers, whether your water is hard, has iron, is acidic or more, Water Tender products can offer a solution for your water problems.


The hardness of water is referred to by grains per gallon and is the result of calcium and magnesium dissolved in water. Hard water can shorten the lifespan of appliances and cause accumulation of soap scum on fixtures and dinnerware. 

See: Water Softeners
 Hardness table
Less than 1.0 gpg  Soft
1.0 - 3.5 gpg   Slightly Hard
3.5 - 7.0 gpg  Moderately Acidic
7.0 - 10.5 gpg  Hard
10.5 and over  Extremely Hard


Iron is a common problem in well water, causing orange staining on fixtures and laundry. Iron is mainly present in two forms: soluble ferrous iron (clear or colorless) or insoluble ferric iron (reddish brown substance).

See: Iron Handlers
   Iron Levels
Less than 0.05  Excellent
0.05 - 0.3  Good
0.3 - 0.4  Usable
0.4 - 0.5  Passable
Over 0.5  Unacceptable


Nitrates can show up in groundwater near farm/agricultural and industrial areas, this problem is caused by fertilizers, livestock manure, human sewage and ammonia waste. Water must have no iron and less than 4 gpg hardness before Nitrate treatment.

See: Nitrate Removal Units
   Nitrate Levels
Up to 10.0 ppm  Recommended
Up to 10.0 ppm  EPA's MCL
0.0 - 0.9 ppm   Minimal nitrogen
1.0 - 9.9 ppm  Noticeable nitrogen


Chrlorine is a common problem in municipal water. It can strip natural oils from hair and skin, causing dryness and premature aging. Chlorine can also destroy plastic and rubber seals and gaskets in appliances, causing leaks. A backwashing carbon filter eliminates chlorine, odor and unpleasant taste.

See: Taste & Odor Carbon Filters, Softener & Carbon Filter Combo (for city water)
   Chlorine Levels
Up to 0.3 ppm  Recommended
Up to 4 ppm  EPA's MCL
0 ppm  No chlorine
0.1 - 1.0 ppm   Moderate chlorine
1.1 - 5.0 ppm  Chlorine taste
5.1 - 10.0 ppm  Heavy chlorine taste


Sediment is commonly found in well water, it can clog valves and fixtures and ruin your appliances. Sediment cartridge filters are widely available, but these filters can only handle low flow rates and need to be replaced frequently. A backwashing sediment filter requires low maintenance.

See: Sediment Filters
   Turbidity Levels
Up to 5 ntu  Recommended
Up to 10 ntu  Slightly Cloudy
10 - 100 ntu   Cloudy
100+ ntu  Very Cloudy

Acidity (low pH)

Low pH causes blue or green stains and corrosion of plumbing fixtures. It can also cause pitting of porcelain and enamel fixtures and dishes. An acid neutralizer can prevent and solve these issues by increasing the pH level of water to a safe limit.

See: Acid Neutralizers
   pH Levels 
7.0  Neutral
6.8 - 6.9   Slightly Acidic
6.0 - 6.7  Moderately Acidic
4.0 - 5.9  Extremely Acidic
