How does descaling work?

This engineered technology naturally and effectively inhibits scale buildup by transforming dissolved hard minerals into inactive microscopic crystal particles that are harmlessly passed through your water and down your drain.

Will descalers help my appliances?

Not only will a descaler protect and extend the life of your appliances, but it will also safeguard your home's internal plumbing from the harmful effects of scale buildup.

Why is water leaking from the tank connection?

If you are experiencing a leak from the descaler tank, turn off your water supply immediately. Ensure a tight connection throughout the installed system with a wrench. Do not over tighten as that could cause cracks and further leaking .

What do I need to install the unit?

The following is needed for installation: Drill, wrench, channel locks, crimping tool, plumber's tape, PVC pipe cutter, PVC primer & glue. We recommend using a professional if pipe cutting is required. Basic plumbing knowledge is recommended.
