What Is Backflow Replacement?
Backflow replacement is the full removal of an aging, failed, or condemned backflow prevention assembly and installation of a new, code-compliant device. Replacement is typically recommended when a device is too old or corroded to be reliably repaired, when repair costs approach or exceed replacement cost, or when the existing assembly no longer meets current water district specifications.
Ontario Backflow Tests handles the complete replacement process: we remove the old assembly, install a new approved device, perform the initial certification test, and file your results with City of Ontario Utilities or your local water district. You're back in compliance in a single visit.
We provide honest, upfront recommendations — if repair is genuinely the more cost-effective option, we'll tell you. We don't push unnecessary replacements. Our technicians know the lifespan and failure patterns of all major brands and will give you a straightforward assessment.
Why It Matters
Backflow prevention assemblies have a finite service life. Older devices — particularly those installed more than 15–20 years ago — can fail repeatedly and become unreliable even after repair. A device that fails multiple consecutive tests is a signal that replacement is the more practical solution.
City of Ontario Utilities and neighboring water districts occasionally update their approved device lists, which means older assemblies may no longer meet current requirements even if they still function. Our technicians stay current on approved models and can identify when a replacement is needed for compliance reasons, not just mechanical failure.
