Is this your water?
Dissolved solids, chlorine and harmful chemicals reduce the quality of water and make it less suitable for everyday use. Reverse osmosis pushes water through a special membrane that blocks unwanted elements, reducing bacteria, heavy metals and other harmful substances. The result is purified water for drinking, cooking and ice, and a long-term answer that eliminates the need for bottled alternatives.
Untreated water also leaves residue on appliances and surfaces: spots on dishes, film on sinks and fixtures. By reducing sediment and dissolved minerals at the tap, our reverse osmosis systems keep kitchens cleaner and small appliances running longer. Businesses benefit too, by providing safer drinking water for employees and customers.
Our team guides each step of the process and recommends the right system based on your water quality, household needs and usage habits. Our high-efficiency model recovers 99.9% of the water instead of sending four to twelve gallons down the drain for every gallon produced.

What we install
Fit neatly under the kitchen cabinet and deliver purified water from a dedicated faucet and the refrigerator line. Fresh, great-tasting water without buying bottled alternatives.
Restaurants, offices and other businesses depend on reliable filtration for food preparation, beverages and employee hydration. Commercial-grade systems sized for the demand.
Filters and membranes collect contaminants over time and lose effectiveness. We replace worn components and clean the unit on a schedule, so the water stays consistent with no surprises.
When a well test comes back with arsenic or other dissolved contaminants, an under-sink RO treats the water you actually drink without changing the main plumbing.

What neighbors across the Twin Cities say after we leave.
Tony came out to do an assessment when our old water softener quit working. He did a water test and provided some recommendations and options for new equipment. He was able to install the new equipment within days of us deciding which route we wanted to go. Great service and great prices!
We had Taplin install a water softener a couple years ago. They were so great we had them back for a filter this year. Tony was clear on communication, super fast to schedule and quick on install. He even answered all my questions before and after the fact. Products are easy, 0 maintenance. Go with Taplin, they're great!
Talk about customer first! Knowledgeable, fast, and genuinely committed to doing things right. Fair pricing and exceptional service. Couldn't be happier with my water softener install. So glad I found them! Highly highly recommend.
After much research on local companies we decided to go with Taplin Water and I'm very glad we did. Taplin is a family owned business and Tony is a very stand up guy. It literally took him about 30-45 minutes to install an iron filter.
Other services
Most well-water homes need a softener and an iron filter together; most city-water homes pair a softener with carbon.
