Over 10,000 cases of backflow contamination of drinking water are reported each year, and some backflow cases can have fatal consequences.

Just give us a call any time, day or night, and we'll have a licensed expert at your door in no time.


How much does backflow prevention service cost in Minneapolis-St. Paul?

Diagnostic Cost: $88

We'll arrive at your home and perform a diagnostic of your backflow system for just $88, or for free if you're a Total Comfort Club member. While price varies depending on the extent of the service, you can always count on MSP to give you honest advice and multiple repair options.

What factors does MSP consider when determining price?

  • The cost of a replacement device: If your backflow preventer is being tested or requires repairs, chances are the service will be more affordable than installing a replacement device. The good news is replacement backflow preventers are fairly affordable and shouldn't take more than an hour or two to install.
  • The plumber you hire: When hiring a plumber, value is always more important than price. MSP, for example, sends only licensed experts to our customer's homes and installs only the most reliable backflow preventers by the best brands. We also offer a 100% satisfaction guarantee, so if something does go wrong, we're there for you to make it right. You may find a plumber who will install a device cheaper, but you won't find one who will install one better than MSP.

Customer Testimonial

MSP is highly recommended!

Great experience! Jeff was professional, thorough, and personable. He explained what the issue was and how he fixed the issue. A lot better than a different plumbing company that came out a couple of weeks ago who did not resolve the issue and took advantage of us. MSP is highly recommended!
