Does RO water leach minerals from your body?
According to recent cellular studies, drinking pure ro/distilled water does not reduce valuable minerals from living human tissue. There are two types of minerals: organic and inorganic minerals. For example the calcium found in water is inorganic calcium. Inorganic calcium is the result of dissolved rock and soil in the water. This inorganic calcium is food to plant life and nothing but rocks to human life. Humans absorb organic calcium found in fruits and vegetables.

Does drinking RO water affect my bodies PH?
Absolutely not. Let's think back to the properties of PH. The PH scale is 1 to 14 and 7 being neutral. RO water purified on Maui is usually around 6 - 6.9 so it is slightly on the acidic side. Now, in order to make an 8 ounce glass of purified water neutral you can add 1 - 2 specks of Baking Soda (a base). Now instead of adding a spec of baking soda to every glass of water you drink think of where that water goes after you put it in your mouth. Well in your mouth are enzymes that are naturally acidic in nature that are used to start the digestion process of breaking down the food we eat - then the water reaches our stomachs which is more acidic. As soon as the purified water enters your mouth it becomes acidic even if you added a spec of baking soda to your glass.

Why is the process called Reverse Osmosis?
If you think back to your 7th grade science class you'll remember (or try to remember) that osmosis is the natural tendency of a solution to travel from one solution to another through a semipermeable membrane. This natural tendency of osmosis is to pass from the diluted solution to the concentrated solution thus equalizing the concentration of both solutions. When we add pressure to the more concentrated side of the membrane (tap water) we reverse the natural tendency of osmosis therefore physically pushing the more concentrated solution through the membrane. This process removes dissolved solids, inorganic and organic material down to a specific molecular weight from the water. The reject water with all the contaminants (concentrate) is then diverted to the drain.

What is UV light?
Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun. The water treatment industry uses high-powered form of UV light called UV-C or "Germicidal UV" to disinfect water.

How does UV work?
UV-C rays penetrate the cells of harmful bacteria and viruses in your drinking water, destroying their ability to reproduce. Without the ability to reproduce, these organisms die and no longer pose a health threat. It's a simple but effective process, with Trojan's system destroying 99.99% of harmful microorganisms.

Why not use chlorine?
Chlorine changes the taste and odor of water. Chlorinating also produces harmful by-products called Trihalomethanes (THMs) which are linked to cancer.

Does a UV system consume a lot of energy?
No, the UV unit will consume about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality.

What is "hard" water?
Hard water is water which has been exposed to rock containing calcium, magnesium or a combination of both. These minerals dissolve into the water over time which is then referred to as hardness. Hardness causes lime or scale buildup on plumbing fixtures and appliances and reduces the cleaning ability of soaps and detergents. Hard water is expressed in grains of hardness per gallon of water.

    Soft Water..............0 - 1 grain per gallon
    Slightly Hard Water........1 - 3 ½ grains per gallon
    Moderately Hard Water..........3 ½ - 7 grains per gallon
    Hard Water..............7 - 10 ½ grains per gallon
    Very Hard Water..............Over 10 ½ grains per gallon

How does a water softener remove "hardness: from water?
Water softeners work on the principle of "ion exchange". "Ions" are electircally charged atoms or groups of atoms. Tiny beads of plastic (called resin) inside a water softener mineral tank are surrounded by ions of sodium or potassium which have a weak magnetic attraction to the resin. Calcium and/or magnesium ions (hardness) have a stronger magnetic attraction to the resin than the sodium or potassium. When these hardness ions pass near the resin, they are attracted to it so strongly as to knock the ions of sodium or potassium off the resin bead and take its place. Therefore, one ion is exchanged for another in the water.

How much sodium does softening put into the water?
For each grain per gallon (17.1 mg/L) of hardness, a softenener will put 30 mg/gal (7.9 mg/L) of sodium in the water. The US FDA defines the water that would result from softening 100 gpg (1710 mg/L) hard water as a "low sodium" beverage. It should be noted that Most of Maui's areas that are affected by hard water have hardness around 8 gpg.

Do I need any other water treatment equipment with a water softener?
It depends on the quality of your water. Each area of Maui is unique and Water Source specializes in addressing each problem area with specific equipment.

I've heard that using soft water for laundry is better for my clothes; just how beneficial is soft water when it comes to laundry?
A case study by Joseph E. Mears described in detail the benefits of softened water at the Benjamin Franklin Hotel in Philadelphia. The study concluded:
  1. Linen life was almost doubled with soft water.
  2. Laundry soap consumption dropped from 3 lbs. per load to 1 ¼ lbs. per load.
  3. Due to the reduction in soap usage, washing times were reduced by 6 to 8 minutes per load.
  4. The downtime on six 305 hp boilers was decreased appreciable with a savings of 50 man hours per month per boiler.
