I rely on my filters.

Every nine months I replace my filters to remove the iron out of my well water. What a difference it makes. Thank you, CASCADIAN for your quality products.

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.
