What’s in your water?

Like many American cities, many neighborhoods in and around Chicago struggle with poor water quality. Given the age of municipal pipes, lead contamination is particularly concerning. A 2018 Chicago Tribune report found that 30% of sampled homes had lead levels above 5 parts-per-billion. Health care professionals and researchers agree: there is no such thing as ‘safe’ levels of lead exposure. Lead can make adults sick and impair the proper growth and development of children.

Most lead is delivered to the home through aging, lead service lines. Cities are slowly replacing these lines, but experts advise homeowners take steps to protect their drinking water until this transition is complete. Their recommendation: drinking water filtration systems.

A water filtration system removes lead and other contaminants from water before it reaches your sink faucets, refrigerator, or shower head. By doing so, it drastically improves both the taste and quality of your water.

“Ray’s customer service and plumbing expertise was second to none. Cannot recommend him and this company enough, they’re totally legit.”

“I have to say it was a pleasure working with King. I would highly recommend them and will definitely use them in the future.”

Reverse Osmosis

We install reverse-osmosis (RO) home water filtration systems. Either mounted below your kitchen sink or providing whole-home water filtration, RO is the solution to your water quality concerns.

Water Softeners

Hard water is rough on your appliances and pipes. It leaves scaling on faucets and fixtures, and adds a strange taste to drinking water. Have us install a water softener in your home.

Water Quality Testing

Want to learn more about your home’s water quality, including whether or not your water has elevated lead levels? Call us, and we’ll arrange to have your water tested by one of our plumbers.
