Your water problems, our solutions

For every water problem, there is a solution. And we have solutions.

Here are some common water problems you may have and the products we use to correct them:

  • My water is colored.
  • My water tastes bad.
  • My water smells bad.
  • My water stains.
  • My water is ruining my plumbing.
  • My water is contaminated.

It is the characteristics of your water and your water analysis results that dictate the choice of devices we will offer you.

Different elements can be responsible for the color.

For example:

  • The iron gives the water an orange color.
  • The tannins give the water a yellow color.
  • Sulfur gives the hot water a gray color.

Solutions :

  • For iron: catalyst filter or water softener
  • For tannins: water softener or chlorination followed by an activated carbon filter
  • For sulfur: catalyst filter

Several elements can influence the taste of water.

For example:

  • Iron and manganese give the water a metallic taste.
  • Acidic water in copper plumbing gives a metallic taste.
  • Bleach added to a water system gives a chlorine taste.


  • Iron and manganese: catalyst filter or water softener
  • Acidic water: neutralizing filter
  • Chlorinated water: activated carbon filter or reverse osmosis

Sulfur is the element usually responsible for odors in water.

For example:

  • In well water, the presence of sulfur gives a rotten egg smell to all the water in the household.
  • In a water heater, the magnesium rod can react with the water and cause a rotten egg smell in the hot water.


  • Sulfur: Catalyst Filter
  • Magnesium rod: replace the rod with a corrosion protection anode, either aluminum or electronic

Several elements favor the appearance of stains.

For example:

  • Iron and manganese are responsible for orange and brown stains on plumbing fixtures and clothing.
  • Hard water, rich in calcium or magnesium, is responsible for white spots on glassware and utensils.


  • Iron and manganese: catalyst filter or water softener
  • Hard water: water softener

Various elements can wear out piping and fittings prematurely.

For example:

  • Aggressive water, i.e. water with low alkalinity, hardness and pH.
  • Chlorides and salt present in the water in very large quantities.


  • Aggressive water: neutralizing filter
  • Chloride and salt: reverse osmosis and water mineralization with neutralizing filter

Surface well water and water from lakes, rivers, streams and springs are particularly vulnerable to bacterial contamination.

There are several things that can lead to bacteria in the water.

For example:

  • The presence of dead animals in a well.
  • The presence of septic systems near a well.
  • Earthwork near a well.


  • Surface well water: UV disinfection or chlorination
  • Lake water: UV disinfection and/or chlorination
