What’s in your water isn’t always transparent. While some contaminants can cause foul odors or smells, others can go completely unnoticed. Luckily, your local St. Joseph Culligan Water® experts know firsthand about common water issues in your area. With a free, in-home water test, they can check levels of water hardness, chlorine, total dissolved solids (TDS), iron and other common issues – with results in 30 minutes or less. Your St. Joseph Water expert may also send your test to our IL-EPA certified lab, which can test for a broad range of issues including lead, copper, bacteria and other contaminants. Your local dealer will make the process seamless, so you’re not left wondering how to test water quality at home on your own.
