About Louis Water Co

About the Owner

Jake McMillian

I am Jake McMillian, owner of Louis Water Co in Phoenix, Arizona. I started this company after learning how toxic our water is in Arizona. I knew water was a crucial part of everyday life, and as a Dad, I wanted the best for my family.

Anyone who has lived here for more than a few months has seen what it does. Scale on every faucet, crusty white spots on glass, dishes that come out of the dishwasher cloudy, water heaters that fail years before they should. The water is technically safe to drink, but it is hard on homes, hard on appliances, and full of toxic chemicals like chlorine, arsenic, and PFAS. Check your water at EWG.org.

Our mission is to bring cleaner, safer water to Phoenix families without the hefty price tag or high-pressure sales tactics.

What Makes Us Different

Why Phoenix Homeowners Choose Louis Water Co

No In-Home Sales Pitch

Most water treatment companies require an in-home consultation that is really a two-hour sales pitch with today-only pricing. We do not operate that way. We give you a quote based on your home and water concerns over the phone or through our form. No theatrical process, no pressure.

Real, Honest Pricing

Not only do we guarantee your price, we also have some of the best priced systems in the state. The price we quote is the price you pay. No hidden fees, no surprise charges, no upsells on install day.

We Don't Just Soften, We Filter It

Our main system comes with coconut shell activated carbon to filter out chlorine and chloramines before the water hits the resin bed to soften. This brings clean, soft water to every tap in your home, not just soft water.

Built for Phoenix

Every system we carry is sized and configured for Phoenix's specific water: high TDS, very high hardness, varying chlorine, and on the well side, iron and sulfur. We know this water. We live here too.

🇺🇸

American Built

Every part of our systems is built, used, and sourced in the United States. Nothing comes from overseas. Our systems come straight from Honest Water Co in Fort Worth, Texas, one of the most respected water treatment manufacturers in the country.
