Get matched with top water treatment & purification system installers and replacers in Minneapolis, MN

"We decided to have our softener fixed instead for replacing. Did not choose Northern Plumbing for the task."

"These folks are awesome! From start to finish, they were pleasant, helpful, considerate, and knowledgeable. I contacted them this morning, and by 3, I had a new water heater (and it was a difficult installation, let me tell you). Also Erik took the time to figure out the best and least expensive option. He deserves a medal, because he saved me thousands (did I mention it was a difficult installation?) Now I won't use anyone else for my plumbing needs. Thank you all!"

"The installation was done quickly and done well. The customer service was very professional. The only negative of this transaction was the cost of the project. It was the cost they told me it would be but I was just surprised that a replacement water softener system would cost that much. Overall I would definitely recommend this company."

"We had an issue with our water conditioning system for Aquarius. They attempted to remedy the problem and determined they needed to replace the system. With the system being over 5 years old, I was uncertain what it would cost me, however, the only thing better than the equipment they provide is their customer service. No cost to replace with a better system. Now that is service!"

"They were knowledgeable and did a great job of eliminating specific lights and switches to narrow down the root cause, which was the brand of circuit breaker that was previously installed. With a different brand installed we haven’t had any issues."

"So happy about our RO System! Thank-you James F! Also, thank-you Brandon H for informing me about the benefits of water treatment! Best decision I have made in 2021. James did a great job explaining everything & answered all my questions. Nice guy & professional from start to finish. Thank-you Aquarius."

"Did a great job. Very pleasant. Came out the day I contacted them. Had new water heater installed and old one out around 2 hours. Little on the higher end cost wise maybe... But you get what you pay for and the technicians don't set the price. "

"We used Finken when we built our new home. They were so helpful from beginning to end and now with service these last 5.5 years. We love the automatic deliveries of salt and reverse osmosis filters. We were previous water dispenser customers also and the automatic water jug deliveries were also great! We recently had them out as our Reverse Osmosis system was making a buzzing sound and they were quick to diagnose and provide a fix. Everyone is knowledgable and friendly and we will use Finken for life!"

"They performed an A/C heater check and provided estimates of what it would cost to replace them. I highly recommend them."

"Our water heater had been leaking. I contacted Dean’s Home Services on Thursday AM 3/5/2026. Their representative Mike Washburn arrived that afternoon. He discussed our options, and we chose a Bradford White water heater. Mike arranged for an install the next day and disconnected the old water heater. At 8:00 AM the next day installers Cody Washburn and Sebastian arrived. The new water heater was installed in an hour and a half. The old heater removed and cleanup completed. We had hot water in less than 24 hours after our original call. Mike, Cory and Sebastian were very helpful and professional. We could not be happier!"
