Can air in pipes cause low water pressure?
If you’ve encountered these issues recently, you likely have air trapped in your water pipes.

Air in the water piping system can cause rust and corrosion.
Will an airlock clear itself?
Airlocks do sometimes fix themselves, but it isn’t a risk worth taking. Airlocks occur when air becomes trapped in the hot water or central heating system. Vapour becomes caught in a high point of the pipework because the gas is less dense than the water in the system.
What are the symptoms of air in a water system?
However, trapped air can cause irritating problems such as:
- Excessive noise coming from your walls.
- Reduced water pressure, resulting in weaker flow (especially noticeable in showers)
- Spluttering faucets or inconsistent output.
- Rusting and corrosion in extreme cases.
- And more!
