Whole house water conditioners are of several types. Each type serves a specific function. For example an iron filter removes ferrous iron but does not remove hardness etc. Choice of water conditioner depends on what needs to be removed. Depending on water quality, sometimes two or more water conditioners may need to be installed to filter the water. For example iron filter followed by water softener.
Product Type | Water Softeners (Cabinet and 2-tank) | Water Softener with Iron Removal | Air Injection (Chemical-Free) Iron Filter | Greensand Filter | Chlorine Filter | Chloramine Filter | Tannin Reduction Filter | Back-washable Sediment Filter |
Primary Function (Removal of) | Hard water | Hard water & ferrous iron | Ferrous iron only | Ferrous Iron, Manganese & Hydrogen Sulphide (Rotten egg odour) | Chlorine | Chloramines & chlorine | Tannin s (Colour) | High turbidity - Sediment, sand, silt, grit, and other particulate matter |
Install location | On the main water line before water pipe divides into hot and cold. AFTER pressure tank for well/lake systems & AFTER water meter for city water. Water conditioners treat ALL the water in the home including bathrooms, kitchen and outside taps |
What is Chlorine ?
Chlorine is the most common chemical used by municipalities around the world to make water safe to drink. Almost all municipal treatment plants in North America use chlorine for primary or secondary disinfection. Chlorine can form cancerous by-products with certain organic compounds present in water. In addition chlorine renders an offensive taste and odour to water and to beverages made from such water. Coffee and tea tastes much better when chlorine is removed from water. Many people have reported to be allergic to chlorine in the water.
Chlorine from drinking water can be effectively reduced by activated carbon filter cartridges. All Rainfresh Drinking Water Systems reduce chlorine effectively. For whole house reduction of chlorine , Rainfresh CCF systems are recommended.
Many municipalities across North America treat water by a process called “Chloramination”. It involves disinfecting water by chloramines , which are formed when ammonia is used in addition to chlorine . Chloramines reduce the formation of potentially cancer-causing Trihalomethanes (THMs ), but Health Canada states that there is potential for formation of other potentially dangerous by-products such as haloketones, chloropicrin, haloacetic acids etc, whose health effects are still under study.
Among the known effects of chloramines are bad tastes and odours in drinking water & beverages made from such water. In addition, chloramines can cause skin irritation, are corrosive by nature, and are toxic to fish.
It is estimated that 1/3rd of all Canadians now drink water that has been treated by Chloramines . Major urban populations in Edmonton, Red Deer, Lethbridge, Greater Victoria, Dauphin, St John’s, Toronto & surrounding areas, Saskatoon and many more are now on chloraminated water.
Boiling water or allowing water to sit at room temperature does not remove chloramines from drinking water. Most undersink activated carbon based filters or reverse osmosis systems are also ineffective in removing chloramines .
Rainfresh QCA and CA1 filter cartridges are specially formulated and are tested and certified for chloramine reduction. Rainfresh Whole House Chloramines reduction system reduces chloramines from all the water in the home.
Tannin s are natural organic materials (humic and fulvic acids) formed primarily by the decomposition of plants. In surface waters (lakes, rivers) and shallow wells, tannin s dissolve in the water causing a light yellow to dark tea colour in the water. (Tea and wine have tannic acids and thus the dark colour). Tannin s also stain plumbing fixtures such as bath tubs and toilet sinks, just like iron does.
Tannin s are not considered a health risk, although most people would prefer not to drink water that has a yellow or tea colour to it. Tannin s also severely limit the performance of UV disinfection systems and must be removed if UV treatment is required.
In simple terms, hard water is high in Calcium and/or Magnesium. Hard water does not easily form lather with soap or detergents and tends to leave white scaly deposits on toilet fixtures, bath tubs, shower heads etc. Hardness of water is measured in “grains per gallon” (GPG) or “parts per million (PPM)”. 1 GPG = 17.1 PPM
Hardness of water | Degree of hardness |
Less than 1 GPG | Soft |
1.0 to 3.5 GPG | Slightly hard |
3.5 to 7.0 GPG | Moderately hard |
7.0 to 10.5 GPG | Hard |
10.5 GPG and above | Very hard |
Common evidence of hard water include
– whitish deposits on dishes and glassware
– High soap usage & need for fabric softeners
– Dry, itchy skin and scalp after showers
– Extra work to remove soap curd on bathtubs & shower stalls
– High energy costs, possibly due to scale build-up in pipes and on appliances
– Scale build up in sinks, tubs, faucets & appliances
