Independent Water Testing
We Test the Water First. Then We Choose the System.
Every home’s water is different, so we start with the water itself.
Before selecting the systems we offer, we sent water samples to an independent environmental laboratory in Illinois and tested them for dissolved solids, metals, alkalinity, nitrates, chlorine and bacteria. Based on those results, we chose reverse osmosis systems from carefully selected manufacturers, built for reliable everyday performance.
- Independent lab testing guided our choices
- Systems from carefully selected manufacturers
- 3-Year Manufacturer’s Warranty on every system
We only install in your home what we would install in our own.
