How often does a backflow preventer need to be inspected?
A backflow preventer should be inspected and tested once every 12 months by a certified tester. Springs, seals, and check valves wear over time, so annual testing confirms the device still blocks contaminated water from reversing into clean lines. Some higher-risk systems or heavy-use irrigation may need checks more often; your water provider sets the final interval and paperwork rules. If a unit fails, technicians typically install a repair kit or replace the assembly based on condition, model, and parts availability. We routinely perform certified backflow testing for homeowners around the Jacksonville Beach area.
Schedule sooner if you notice:
- Drop in water pressure right after the assembly
- Continuous discharge from the relief port
- Recent plumbing or irrigation work near the device
- Discolored or gritty water at outdoor spigots
Book your annual test and keep the passing report with your home records.
