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

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

Cory Seaman
I was a little sceptical

As being a plumber for more years than I want to remember I was a little sceptical on using your ICS-H filter. I was taught that the only way I was going to remedy the issue was by using an injection type of system. After an easy installation and draining my water heater the results were quite impressive. The well water here in the Finger Lakes of New York has a strong odor especially when using the hot water. I have my fingers crossed that it will maintain in effect for the next six months of usage because in the summer months the odor increases. Old dogs can be taught new tricks(ideas). Thanks again!

It works flawlessly

We installed our first ICS H2s filter. We put it behind a Nitro System that was randomly allowing H2s by. It works flawlessly. Thanks for the new ICS systems. We bought all 4 for our inventory.
