What Happens If My Backflow Preventer Fails Inspection?
Receiving a failed backflow inspection result can be frustrating, especially if you've received a notice from your utility district requiring annual testing.
The good news is that a failed inspection does not automatically mean your backflow preventer needs to be replaced.
In many cases, the issue can be corrected through cleaning, repair, rebuilding, or replacement of specific components.
Understanding what happens next can help property owners avoid unnecessary worry and make informed decisions about their backflow system.
Why Do Backflow Preventers Fail?
Like any mechanical device, backflow preventers contain internal components that can wear over time.
Common causes of failure include:
✔ Worn internal parts
✔ Debris inside the assembly
✔ Damaged check valves
✔ Leaking relief valves
✔ Freeze damage
✔ Physical damage
✔ Age-related wear
Annual testing helps identify these issues before they become larger problems.
Does A Failed Test Mean I Need A New Backflow Preventer?
Not necessarily.
Many failed backflow preventers can be repaired and returned to proper operation.
In some situations, rebuilding the assembly may be the most practical solution.
Replacement is typically recommended when a device has reached the end of its service life, has sustained significant damage, or can no longer be repaired economically.
Every situation is different, which is why an evaluation of the specific assembly is important before making any decisions.
What Happens After A Failed Inspection?
Once the cause of the failure is identified, the appropriate corrective action can be determined.
Depending on the issue, that may involve:
✔ Cleaning
✔ Repairing components
✔ Rebuilding the assembly
✔ Replacing the assembly
After repairs are completed, the device is generally retested to verify that it is operating properly and meeting applicable requirements.
Why Repair Experience Matters
Testing identifies a problem.
Experience helps solve it.
While many companies offer testing, understanding how to diagnose, repair, rebuild, relocate, or replace backflow preventers requires years of hands-on experience.
