Backflow Prevention Services in Missoula & Western Montana

Protecting your drinking water starts with a properly installed and maintained backflow prevention system. At Garden City Plumbing & Heating, we offer certified backflow prevention services—including testing, installation, and repair—to help homeowners, businesses, and property managers stay compliant and keep their water supply safe.

Backflow happens when there’s a sudden change in water pressure, causing non-potable water (like irrigation water, chemicals, or contaminants) to flow backward into the clean water system. This can pose serious health risks—and it’s exactly why municipalities across Montana, including Missoula, require backflow preventers to be installed and tested annually by certified professionals.

We work with all types of approved backflow prevention assemblies, including:

  • Pressure Vacuum Breakers (PVBs)
  • Double Check Assemblies (DCAs)
  • Reduced Pressure Zone (RPZ) Devices

Whether you need an annual test for your commercial building, a repair on an irrigation backflow preventer, or installation for new construction, our licensed plumbers ensure your system meets local code and functions properly. We’ll complete the necessary reports and documentation required by local water authorities and keep you informed of your compliance schedule.

We serve homeowners, HOAs, commercial properties, and businesses of all sizes. And because we’ve been serving Missoula and Western Montana since 1985, you can count on us for reliable, honest service—every time.

Call (406) 481-3548 or schedule online today to book your backflow test, repair, or installation.
