Reverse Osmosis Drinking Water

Bottled-water quality from your own kitchen faucet — without ever buying a bottle.

Reverse Osmosis Drinking Water Systems

Think about how much your family drinks from the kitchen faucet. Coffee in the morning. Water bottles for school. The pot of pasta on the stove. That water deserves to be the cleanest in your house. If you are hauling cases of bottled water from the store, you are paying over and over for something your own sink can do better. That is the problem reverse osmosis solves, and it is one of the first things I fixed in my own home.

Reverse osmosis pushes your water through a membrane so fine that dissolved solids, lead, and other contaminants cannot get through. Carbon filters alone cannot catch that stuff. We install two styles under your kitchen sink. The tank system is the proven classic. The tankless system skips the storage tank, saves cabinet space, and adds an alkaline filter that puts healthy minerals back in for better taste. Either way, a licensed plumber installs it clean and tests it before leaving.

Here is the best part. If you get a whole house system from us, the reverse osmosis unit is included at no extra cost. Other companies sell it as an upsell. We think filtered showers and clean drinking water belong together. Want it on its own? We install that too. Call or text (636) 204-6233, get a straight quote over the phone, and in most cases we can install the same day. Thirty days later, if you are not convinced, we take it out and refund you.
