First, narrow it down
Does it pour normally for a few seconds before sputtering, or does it spray from the first moment? Does it happen at one faucet or several?
What you're seeing
| Symptom | Possible cause | What to do next |
|---|---|---|
| Starts normal, then spits | Restriction, emptying keg, or leak | Check keg and visible line. |
| Several taps sputter | Shared gas or temperature issue | Record gas and cooler status. |
| After recent cleaning | Air or connection problem | Ask cleaner/service to recheck line. |
What to check
Check the keg and coupler
An empty keg, a coupler that is not fully engaged, or a worn seal can cause irregular flow. Verify the coupler is secure using the normal procedure.
Inspect visible beer line routing
Carbonator’s draft guide specifically lists kinks and heavy objects resting on a beer line. Look behind kegs and along accessible tubing.
Think about recent line cleaning
If sputtering started after a maintenance visit, note the timing. Air pockets or a loose joint can be involved; persistent symptoms should be checked rather than assumed normal.
Look for leak clues
A cracked hose, pinhole, or damaged seal at the keg or faucet can disturb the pour. Do not remove or pressure-test gas fittings yourself.
Check whether the cooling loop is too cold
A partly frozen beer line can begin as weak or erratic flow. Note cooler and glycol temperatures and whether adjacent lines are also affected.
Document the tap and pattern
Knowing exactly which tap sputters and whether it happens continuously or after a few seconds helps identify a line versus supply issue.
Why it happens
Beer should move through a closed, balanced liquid path. Restrictions, gas breakout, and leaking seals can create intermittent bursts of liquid and gas.
Need service?
Call if the symptom continues after visible line and keg checks or if a damaged hose or seal is suspected.
