Certified Backflow Testing & Repair in Eastern Idaho

ABPA-Certified, Backflow Testing, Repairs, and Certification - Prompt, Local, and Compliant.

Backflow prevention assemblies protect your drinking water from contamination — and most cities require annual testing to keep your system in compliance. North Valley Water Management provides certified backflow assembly testing, repair, and new installation for homes, businesses, and municipal water systems across eastern Idaho.

We test all major assembly types (RP, DC, PVB) and file your results directly with your local water authority, so you don't have to chase down paperwork. If your assembly fails, we can typically repair it on the spot.

What's included:

  • Annual certification testing for existing assemblies

  • Testing for new installations before they go into service

  • Repair of failed assemblies

  • Direct filing with your city or water district

  • Same-week scheduling in most cases

Who this is for: Homeowners, business owners, and property managers who received a notice that backflow testing is due, plus contractors needing testing on new assembly installations.
