Hydrotesting (Recommended Every 2 Years)
To ensure the keg remains safe and pressure-rated:
- Replace the red PRV with a grey PRV (borrow from a corny keg).
- Fill the keg completely with water.
- Pressurise to 6 bar using a CO₂ regulator, bike pump, or compressor.
- Hold at 6 bar for 1 minute.
- Depressurise, then reinstall the red PRV.
Perform this test at room temperature (15–30°C).
