My water is perfect!

I love my water. It is clear, tastes great and doesn't stain anymore. I used to have a little bit of sediment that would plug the showerhead at that problem is gone. My iron problems are gone too.

Not much difference

I honestly see no difference in the water quality, except as a sediment filter. No noticeable change in soap lathering, water spotting, etc.

Had the system for 1 year and we are very pleased with the results. We have very hard water and no more spots on our dishes.

Hi Don, We're so happy you're happy with the treatment of your very hard water and that your dishes don't have spots anymore. Thanks for sharing the nice review.

Great customer service on the phone

Online, Devin and I had difficulty with my shoddy connection. But in person we got it resolved and good service and delivery. Only gripe is probably my fault in that we have a UV system too, which also requires annual replacement. Might be good to ask clients if they need that as well.

Hi J K Murphey, So pleased we could help you and thank you for the review.

Cascadian filter replacement

I received my Cascadian filter replacement several months before I needed it. The scheduling got altered, I think, because Cascadian revamped their website and I was asked to sign up again for the auto-refill program. Will try to modify the schedule on their website.

Hi DR RDR,
Thank you for the review. Sorry for any mix up, don't hesitate to contact us if you need any help.

FAQs

Where does ICS go in my Home?

Where it can fit, and where it can easily get access to your home's water source. This is typically a garage, crawlspace, or even a closet. If you have questions a plumber would be able to help you find the best spot. During maintenance you'll need to fit a bucket and have enough space to turn the sump wrench which comes with your system.

How often do I replace the filters?

Most people replace their filters once per year, or sooner if they start seeing issues with their water again. Learn about water issues here

What is the return policy?

If you are unsatisfied within 60 days of purchase, return the housing and we'll refund your purchase no questions asked.

How fast do you ship?

We typically ship same business day if the order is placed before 2 pm PST using UPS ground.

Does this include housing o-rings?

No, the replacement kits do not come with o-rings.
