Recognize Any of These?
Most Greater St. Louis homes have at least one of these problems. A free in-home test tells you exactly what's in your water — and what fixes it.
White crust on faucets, showerheads, and appliances that won't scrub off.
Your water smells like a pool - even after it runs cold.
Orange or blue-green stains on sinks, tubs, and toilets from iron or copper.
Hard water strips moisture - itchy skin and dull hair after every shower.
PFAS, nitrates, heavy metals - invisible problems that add up over time.
You don't trust your tap, so you spend money on cases of plastic every week.
