CuZn Whole House Iron and Sulfur Water Filter System

What Is Iron and Why Is It Bad?

Making up at least 5 percent of the earths crust, iron is one of the earths most plentiful resources. As rainwater infiltrates the soil and underlying geologic formations, iron is dissolved and seeps into aquifers that serve as sources of groundwater for wells. Although present in drinking water, iron is seldom found at concentrations greater than 10 milligrams per liter (mg/L) or 10 parts per million. However, as little as 0.3 mg/l can cause water to turn a reddish brown color.

Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron. Water containing ferrous iron is clear and colorless because the iron is completely dissolved. When exposed to air in the pressure tank or atmosphere, the water turns cloudy and a reddish brown substance begins to form. This sediment is the oxidized or ferric form of iron that will not dissolve in water.

Iron is not hazardous to health, but it is considered a secondary or aesthetic contaminant. Symptoms of iron in your water include:

  • Rust colored (reddish / orange) stains in toilets, tubs, showers and sinks
  • Bad tasting (metallic) drinking water
  • Rust colored stains on laundry
  • Rusty colored water, especially when first turning on the water

How to Remove Stains Caused by Too Much Iron

Here are two methods to remove the stains from your porcelain toilets, tubs, showers and sinks:

  1. A simply and effective product to remove the stains from porcelain toilets, tubs, showers and sinks is Shaws Pads Toilet Ring Remover. These pads use no chemicals and are safe for septic systems. The pads have a short handle and a special pad. You wet the pad, use short vigorous strokes and the scale and stains leave the porcelain and are flushed away.
  2. A pumice scouring stick. Wet the bar and rub it back and forth on the stain, which creates a pumice paste that assists in cleaning and polishing the surface. Rinse when done.

How to Determine How Much Iron Is in Your Water

If there is an iron problem with the water supply, the first step is to determine the source by testing your water. The source of iron may be from the corrosion of iron or steel pipes or other components of the plumbing system where the acidity of the water, measured as pH, is below 6.5.

You can test your water for iron and other problems with a Watersafe Drinking Water Tests Kits, which is an affordable revolution in home water testing. They are a fast -- results in 10 minutes start to finish -- comprehensive in-home water test method. And they provide professional lab-quality results that appear right before your eyes. The Watersafe Drinking Water Test Kit contains everything you need to find out simply and accurately if your water contains unsafe or undesirable levels of 8 common contaminants in city water and 10 common contaminants in well water. more info about WaterSafe water test kits

Well water tests for all 10 of the most common types of harmful contaminants found in private well water, including iron, copper, lead, bacteria, pesticides, nitrates, nitrites, chlorine, pH and hardness. If your home draws from private well water, regular testing (recommended yearly or more) is the only way to ensure the purity of your water and safeguard the health of your family.

What Is Sulfur (Hydrogen Sulfide)?

Sulfur water is a condition where the running water contains a high amount of hydrogen sulfide gas. Hydrogen sulfide is not a health hazard, but is a common nuisance contaminant whose distinctive "rotten egg" odor makes water treatment desirable. Hydrogen sulfide is treated and removed using the same filter as used for iron.

How to Remove Iron and Sulfur from Water

You can remove the stains from your porcelain toilets, tubs, showers and sinks using one of the solutions above, but the stains will return until you remove the excessive iron from your water. KDF85 Process media is most effective in removing iron and hydrogen sulfide from water. Patented KDF process media is 100% recyclable and contain no chemical additives. KDF media is used to help safely reduce or remove chlorine, iron, hydrogen sulfide and heavy metals from water. KDF85 media also controls scale, bacteria, fungi and algae growth.

Backwashing Frequently Asked Questions

Lots of folks have asked questions about the backwashing head on the whole house system. Here are the five most commonly asked questions and the answers.

What is backwashing?
Backwashing is the process of forcing water through the filter in the wrong direction to unclog the dirt and sediment which has blocked the filter. Auto-backwashing filters refresh (backwash) themselves periodically to insure an optimum level of performance and to prevent "channeling". Whole house auto-backwashing filters greatly enhance the performance of softener systems. Backwashing is a common practice for certain whole house and commercial units which are treating large volumes of water for utility purposes but it is not a recognized practice for small point of use drinking water systems.

How many gallons does it use in the backwash?
Around fifty gallons. It could be slightly more or less depending upon water pressure.

How long does the backwashing last?
It lasts approximately 10 minutes.

What is the flow rate of the backwash water?
5-7 gallons per minute flow rate

Does it have to backwash every day?
It's advisable to backwash daily but not mandatory. Often times systems on municipally treated water backwash once every three or four days. Systems on wells are urged to backwash daily. The frequency of backwash depends greatly upon the quality of water.
