A failed backflow test does not automatically mean you need to replace the entire backflow preventer.

H2O Backflow & Plumbing can inspect the assembly, identify the cause of the failure, and determine whether repair, rebuilding, or replacement is the best option.

Common Reasons a Backflow Device May Fail

● Worn internal components

● Check valve problems

● Relief valve problems

● Damaged or worn springs

● Debris inside the assembly

● Leaking components

● Internal parts that are no longer operating properly

● General wear and deterioration

Our Repair Process

Inspect → Diagnose → Repair or Rebuild → Retest

We’ll explain what we find and discuss the appropriate repair or replacement options before proceeding.

After the repair or rebuild is completed, the assembly can be retested to verify proper operation and complete applicable testing documentation.

When a backflow preventer fails testing, rebuilding the existing assembly may be an option depending on its condition and the type of device.

H2O Backflow & Plumbing provides backflow preventer rebuilds for applicable assemblies throughout East DFW and surrounding areas.

Backflow Rebuild Services

A rebuild may include replacement of worn internal components such as:

● Relief valve components

● Springs

● Diaphragms

● Seals and other internal components

We inspect the assembly before determining whether a rebuild is appropriate.

Repair or Replace?

Not every backflow device should be rebuilt. If the assembly is damaged, obsolete, or otherwise not suitable for rebuilding, replacement may be the better option.

We’ll explain what we find and provide the appropriate options.

Retesting After a Rebuild

After an approved rebuild is completed, the backflow assembly can be retested to verify proper operation and complete applicable testing documentation.
