Backflow Repair & Replacement FAQs
Still have questions? We’re happy to explain everything before scheduling, just give us a call.
How do I know if my backflow device needs repair?
Most homeowners discover issues when the device fails an annual backflow test. Leaks, corrosion, or pressure problems can also indicate the need for repair.
When is replacement necessary instead of repair?
Replacement may be recommended if the device is severely damaged, outdated, or if repair costs exceed the value of installing a new certified unit.
Do repairs require retesting?
Yes. After repairs are completed, the device must be retested to confirm it meets local compliance requirements.
Will you handle city paperwork after the repair?
Yes. We complete the necessary documentation and submit results to the local water authority when required.
How long does backflow repair or replacement take?
Most repairs can be completed in about 1–2 hours, depending on the issue and device type.
