Common Backflow Prevention Device Problems
Backflow prevention devices contain internal components that can wear, become damaged or be affected by debris over time.
Common issues include:
Failed Check Valves
Check valves may fail to seal correctly due to damaged components, debris or worn seals.
Leaking Relief Valves
A leaking RPZD relief valve may indicate an internal fault, pressure issue or debris affecting valve operation.
Worn Internal Components
Ageing seals, springs and other internal components can affect device performance and result in failed testing.
Debris Inside the Device
Sediment and debris may interfere with internal valve operation and prevent the device from passing its test.
Backflow Device Rebuilds & Replacement Parts
Where suitable, an existing backflow prevention device may be repaired rather than completely replaced.
Depending on the make, model and condition, repairs may include:
- Dismantling the device
- Cleaning internal components
- Replacing worn seals and check valve components
- Rebuilding the internal valve assembly
- Reassembling and retesting the device
If repairs are not practical or economical, we can provide a quote for a replacement backflow prevention device.
Failed Annual Backflow Testing?
If your backflow prevention device fails testing, we can assist with the necessary follow-up works.
Following repairs, the device must be retested to confirm it is operating correctly.
Where required, updated test reports can be lodged with the relevant water authority.
