Great System - Better Customer Service

"This is a great system that solved my issues with my well water. The issues were a rotten egg smell from the water, mineral buildup at the plumbing fixtures, and iron staining in toilets and shower floor grout. I like that it is a USA-based company that uses good quality components. From ordering through installation through troubleshooting, the customer service team was excellent. I'm a homeowner with some decent DIY skills, but still needed some help with a replacement part and making sure things were installed correctly. I would definitely recommend getting a water treatment system from this company! It seems to be priced at a great value, especially when on sale. (I have had this system up and running for several months now to make sure that things worked well before posting this review. )"

Great, installed in daughter's house

"Great, installed in daughter's house where iron was present in the well water, She and the kids noticed the results , softer hair, skin and using less soap to lather up."

— Mark G. (5/5)

Good system, excellent customer service

"The Customer Service is excellent. My only issue with the system is that I got a Spin Down filter as part of the package. The entire system to include a cartridge filter is a 1” pipe system, except for the spin down filter which is a 1/2” filter. So I would have to go from 1” from my pressure tank, down to a 1/2” to the SD filter, back to a 1” for the rest of the filtration system. Beyond that, everything else is exceptional."

Q&A

FAQ

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-7500UV — 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-7500 can be used with septic. The discharge from the IMS 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 salt system media will last 15 - 20 years depending on water quality.
  • The Iron media will last 7 - 10 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.
