What Is Backflow Replacement?
Backflow replacement involves removing an existing backflow prevention assembly and installing a new one in its place. Replacement is typically needed when a device has reached the end of its service life, has become too corroded or damaged to repair, has been discontinued and parts are no longer available, or no longer meets current water district specifications. Unlike repair — which fixes individual components — replacement provides a completely new assembly with a full service life ahead of it. Our technicians remove the old device, properly dispose of it, and install a new code-compliant assembly. We then perform an initial test and file the passing report with your water district.
Why It Matters
Backflow prevention assemblies have a finite service life. Over time, internal components wear out, corrosion degrades performance, and some older models are no longer accepted by water districts due to updated codes. Continuing to repair an aging assembly can cost more than replacement and still result in repeated test failures. A new assembly installed correctly resets your compliance timeline, eliminates recurring repair costs, and gives you confidence that your property's water supply is protected. Water districts may also mandate replacement of specific older models that no longer meet current standards.
Our Backflow Replacement Process
We evaluate your existing assembly, its condition, age, and your water district requirements to confirm replacement is the right solution.
We select a code-compliant, appropriately sized replacement assembly that meets your water district specifications.
We safely shut off water, remove the old assembly, and prepare the connection points for the new installation.
We install the new backflow preventer to code, including isolation valves and test cocks, and restore water service.
We test the new assembly and file the passing report with your water district — same day in most cases.
