Customer Reviews

Based on 15 reviews
really happy with the support

Haven't fully tried the system yet. But already very happy with the service provided.

Still waiting on Parts

Currently I can not tell if the product is good or not. I can say that the customer service is lacking. It has been over 2 weeks and I am still waiting on replacement parts because the wrong parts were shipped. I was misquoted tdelivery times twice and am still waiting. Honestly not happy and would not recommend your product to anyone.

Excellent customer service

This company takes pride in their company service. My experience was exceptional as an average DIY'er I wanted to better understand a few things and the team delivered. Their instructional videos are great. Pricing is competitive and shipping only took a few days to arrive. Products arrived in good condition and everything is working as expected 2 weeks later.

Great product but an outstanding support

Installed last week. So far so good. But this review is much more about the awesome support provided than the great product itself. 6 months back bought a house & was straight away facing water problems - Irritated super dry skin & hair loss too. Did a 2-month investigative research to determine that salt-less softener (aka conditioners) don't work for the money being paid (~3000 bucks) & paying 5000 bucks for an all-inclusive company like Culligan was not worth it (even though it could have saved me a lot of mental tension). Finalized my research to the best product in the market & bought it. 1 week in & my 3-yr old has stopped scratching her precious skin, my wife is not complaining about her life-less hair anymore & that's a solid GOLD for me. 5 stars. Hired a local plumber as I'm not handy enough & he made a mess of things.
This is where I panicked & reached out to my trusted handyman (Chris) who was kind enough to complete this half-done job on the next day (Sunday). Also called 602abcwaters & by my luck stars was put in touch with their master plumber (Bryan). Bryan is such a gentleman at hearing to my full panic-induced talk & assured me that he will support the installation all way through, even if it was on a Sunday. Bryan looked at the job done by my local Plumber & was furious too. He recommended the sharkbite connectors & replacements for the broken parts.
Sunday - Chris & Bryan were such supporting pillars in helping me get the carbon tank & water softener into works. In fact, Bryan was in Arizona & on SMS, answering/assuring all my amateur stupid questions from 10am CST to 5pm CST. The installation was finally complete. If 602abcwaters has a golden goose, that they should always keep forever, it's Bryan. The master plumber, with 30-yrs of plumbing background, talking a noob through his fears. If this is not a company I would trust, what is? Thank you

Water System


Why Do You Need This?

Pairing the 2 water systems produces 3 customer benefits:

Benefit 1: Filter & Soften Entire Home Water. Removes hard water and unwanted contaminants, smells & tastes from water prior to entering your home.  The whole house will have carbon filtered softened water.

Benefit 2: Extend Water Softener Resin Media by Up to Decades.  Our premium granular activated carbon (GAC) filtration media will prevent chlorine from destroying your water softener resin.  If the carbon media is properly maintained, your water softener resin media could possibly last for decades.

Benefit 3: Easy Install & Low Maintenance.  As you will see in our reviews, our customers tell everyone how easy this package is to install.  The water softener requires an occasionally bag of salt, and the carbon filtration media won’t need to be changed for years depending on your water quality.  We can teach you how to change media when it’s time.
