Can I trust my well water supply?

Unfortunately, private wells are non-treated water supplies and more susceptible to contaminants and bacteria. The best way to ensure clean tap water throughout your home is to keep pollutants out of the water before it enters your home in the first place. The level of contamination and bacteria can vary from month to month and impact the level of filtration that is required.

That’s why Kind recommends upgrading to the WS-6500UV — featuring the latest Ultra Violet (UV) purification for complete protection. This powerful final stage of treatment uses concentrated UV light to neutralize harmful microorganisms, including bacteria, viruses, and pathogens, without adding any chemicals to your water. When it comes to the quality of water you drink and bathe in every day, there can be no compromise.

What is the warranty?

Our systems come with a limited lifetime warranty on the tanks and 7 Year Warranty on the Electronic Heads, as well as a 120-day satisfaction guarantee, This means you can return it for any reason if you are not 100% Satisfied.

Can I use this system on Septic?

Yes, the WS-6500 can be used with septic. The discharge from the backwashing carbon filter will not disrupt the probiotic bacteria colonies that break down waste in your septic system. There is some concern about the sodium in the salt-softener discharge, but modern efficient softeners do not use as much salt as previous era softeners. We have never received feedback from customers over damaged septic systems due to our salt-softener.

Can this system be installed outside?

Yes, the system can be installed outside as long as the electrical components are protected from the weather. Operating temperature outside has to be between 39°F and 113°F.

What is the maintenance on the system?

  • The sediment filter is designed to be replaced once a year.
  • The carbon media should be replaced every 600,000 gallons of water or 5 years, whichever one comes first.
  • The salt system media will last 15 - 20 years depending on water quality.

How do I know which system to order?

You should always start with one of our Water Test. Testing the water will guarantee you are buying the correct system for your water quality problem.

The cost of your water test will be fully credited toward any system purchase.
