When dry-hopping a beer you add loose particles to the wort. All these particles need to be removed from the wort (through the trub-container) before tapping. If you tap a beer with particles still floating in it, the tap line can get clogged, preventing you from serving your beer.
HOW TO CHECK CLOGGED TAP LINE
Check if there is pressure in the keg by pulling the pressure relief valve open for a short time. If you hear a hard hissing sound, there is pressure. If there is no pressure, pressurize the keg with a CO2 canister, and start serving.
If there is pressure in the keg, you can try clearing the tap line by following these steps:
- Release the pressure from the keg by pulling the pressure relief valve until no sound is heard anymore
- Open the keg lid and check whether the plastic tube is attached to the bottom of the lid. If the tube is not attached, reattach it, then pressurize the keg with a CO2 canister, and start serving. If the tube was already attached, follow the next steps.
- Connect a full CO2 cartridge to the pressure regulator, and connect the regulator to the tap line (not the CO2 line)
- Fully open the CO2 pressure to blow out the tap line (if no airflow is heard, increase the pressure)
RECONNECT THE TRUB CONTAINER
- Reconnect the trub container following these steps:
- Place the keg on the keg stand
- Sanitize the trub container, and fill it with CO2, then connect the trub container to the bottom of the keg
- Shake the keg vigorously to move the trub around in the beer
- Place keg back on the keg stand and connect the keg to power
- Open the bottom valve
- Leave the beer to let the trub settle in the trub container, and after at least 24 hours remove the trub container
- If there is still a lot of trub in it, reconnect the trub container following the same steps. Otherwise, pressurize the keg by connecting the regulator to the CO2 line with a CO2 canister attached to it, and try tapping your beer again.
A FEW USERS TIPS
- If the lid is still stuck, an extra hint is to rinse hot water from above (or through the bottom valve if keg is empty) to make the lid open. Always pull the pressure relief valve first.
- Make sure that both the inside of the tap line and connection on the lid is dry before connecting both.
