    Welcome to the The Charger Water Quiz

    To begin, please fill out the short registration form, and then begin the quiz.There are 20 questions.
Questions you answered incorrectly in Red below:
  1. What is hard water?
    The sum total of calcium and magnesium bicarbonates in water?
    Hard water is water that has high mineral content (mainly calcium and magnesium ions) (in contrast with soft water). Hard water minerals primarily consist of calcium, and magnesium metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates. Calcium usually enters the water as either calcium carbonate, in the form of limestone and chalk, or calcium sulfate, in the form of other mineral deposits. The predominant source of magnesium is dolomite.
  2. A water softening unit is the "Cure" for all your water problems?
    FALSE
    A water softener is not a cure all. A water softener only "softens" water via Ion Exchange.
  3. A water softener reduces the "Total Dissolved Solids" of your water?
    FALSE
    FALSE, A water softener does not reduce total dissolved solids. It exchanges calcium and magnesium ions for sodium ions.
  4. Due to recent and new developments thru science and technology, water softeners have become a more complicated and less reliable appliance.
    FALSE
    FALSE Water treatment systems are more reliable and efficient due to science and technology.
  5. The principle of "Softening Water" involves the process of:
    Ion Exchange
    Water is "softened" thru the process of Ion Exchange, exchanging calcium and meagnesium ions for sodium ions inside the softeners mineral tank.
  6. To Recharge, or Regenerate, a Water Softener, common Table Salt can be used?
    TRUE
    Common table salt can be used to recharge a softeners media bed with sodium.
  7. The process of "Backwashing" a Water Softener means:
    Reclassify and clean the media bed during the process of regeneration.
    Backwashing is usually the first of the regeneration cycles, recersing flow thru the media bed to clean and reclassify the softing media.
  8. A Standard water softener will remove high amounts of iron?
    FALSE
    A water softener can remove "clear water iron", but the softening media is not designed for iron removal.
  9. Compensated Hardness is the hardness of a water supply combined with the iron content. How many grains of hardness are required to compensate for one PPM of Iron?
    4 grains?
  10. Generally speaking: To Properly size a water softener for residential use, what of the following information would be required?
    All of the above
  11. Water is considered "Moderately Hard" when it tests at:
    1.0 - 3.5 grains?
  12. A Residental gas water heater, operating on moderately hard water, will consume approximately 30 percent more energy to heat water than a heater operated with softened water. Under the same conditions, an electric heater will use about 22 percent more energy.
    TRUE
    TRUE
  13. A water softener can improve the efficiency of soap and cleaning products, reducing the yearly cost for these products by up to $900.00 for a family of five.
    TRUE
    Soft water greatly improves the efficiency of soap and cleaning products.
  14. A Reverse Osmosis unit, Commonly called R/O, can usually function properly on raw, or untreated, water?
    FALSE
    Most reverse osmosis membranes will tolerate hardness up to 11 grain per gallon, zero iron and zero sulphur. Water containg Iron, Sulphur or hardness higher than 11 grains must be treated to remove the iron and sulphur and reduce hardness to appropriate levels.
  15. A residential R/O system rated at 30 gallons of water per day will deliver that amount of water for daily home use?
    FALSE
    The ratings for R/O systems are usually "laboratory" ratings. Expect lower performance by the R/O system in field applications.
  16. One reason R/O water is considered better than bottled water is R/O can actually reduce the TDS ( Total Dissolved Solids) of water by up to 95 percent?
    TRUE
    TRUE
  17. An R/O system is actually more convenient than bottled water or a water cooler?
    TRUE
    With an R/O system you have an almost unlimited supply of treated water at your tap.
  18. To properly size an R/O system, which of the following info is required?
    All of the above
    To size an R/O system Water Tempertaure, Hardness, Iron and Sulphur content and water pressure all need to be considered.
  19. R/O water has many uses in the home, including which of the following?
    All of the above
  20. An R/O membrane, the units main component, will last up to three years under normal use?
    TRUE
    TRUE, as long asfilter changes are made at the prescribed intervals.
