Water FAQ’s

Can you repair products that are not Kinetico?

100%! Our trained experts are well-versed in several water brands. Give us a shout and we’d love to talk to you about any and all repair needs.

What should I do if my water smells strange?

There are multiple smells that can come from our drinking water.

  • Sulfur or Rotten Eggs Odor
  • Chlorine/Bleach Odor
  • Sewage Odor
  • Earthy Odor
  • Metallic Odor

Depending on which odor you’re smelling, you’ll want to contact us for some solutions. Sulfur means hydrogen sulfide, bleach can mean your city has upped the amount of chlorine in the water supply, sewage can mean toxic bacteria, earthy means there is a high tannin concentrate present and metallic can mean a high concentration of iron or a low pH.
