How it works
Four steps, in this order
Test
A water test at your kitchen sink, with you watching. It checks hardness, chlorine, iron and pH, and the results come back in about 10 minutes.
Size
We size the system to the test result and to your household's flow rate.
Install
Licensed plumbers install it with a bypass valve, so water can be routed around the system when it needs service.
Service
Filters and media wear out. We change them and repair the system when it needs it.
