Frequently Asked Questions

Where does the ICS system 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

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