An airlock is a blockage of air in a pipe or system, preventing the proper flow of liquid. You'll know you have an airlock based on several telltale signs, depending on the system affected.
Identifying Airlocks in Different Systems
-
Plumbing: In your home's plumbing, an airlock often manifests as:
- Cold spots on an otherwise functioning radiator: Trapped air prevents hot water from fully circulating.
- Tapping or banging sounds from your heating system: These noises indicate air moving within the pipes.
- Lower than normal boiler pressure: This might occur after bleeding radiators to release trapped air.
- No hot water from taps: This strongly suggests an airlock in the hot water supply pipes.
- Mixed faucets running cold but not hot: This is a common symptom, as air pressure interferes with hot water flow. Source: Pulse Plumbers

Homebrewing: In homebrewing, an airlock (the equipment) signals fermentation by producing bubbles. However, lack of airlock activity after an initial period of bubbling could suggest a problem. Also, a constantly overflowing airlock indicates vigorous fermentation. Source: BeerSmith Home Brewing Forum Source: Northern Brewer General Forum

Other Systems: Airlocks can occur in other systems as well, and identifying them may depend on the specific context and the system's normal behavior. For example, the observation of an airlock in a video game may be interpreted differently than an airlock in a spacecraft, so context is important.
Troubleshooting Airlocks
If you suspect an airlock, troubleshooting methods will vary depending on the system. For plumbing, this might involve bleeding radiators or using a vacuum cleaner to extract air from the pipes (Reddit suggests this approach).
