Have you ever turned on a tap only to find no water coming out? Or noticed a sudden drop in water pressure along with strange gurgling or banging sounds from your pipes? If so, you could be dealing with an airlock—a frustrating issue that can disrupt your water supply and potentially harm your plumbing system.
Read on to learn what an airlock is, what causes it, how to identify the symptoms, and what you can do to fix it.
What Is an Airlock in Pipes?
An airlock occurs when air becomes trapped in a section of your plumbing system, preventing water from flowing properly. This trapped air creates a blockage, disrupting the smooth operation of your water supply and reducing system efficiency.
What Causes an Airlock in Pipes?
Airlocks can happen for several reasons. Common causes include:
Improper pipe installation – Poor installation can create pockets where air can accumulate and get trapped.
Sudden changes in water pressure – These fluctuations can draw air into the system.
Leaks in the plumbing system – Even small leaks can allow air to enter and become trapped.
Empty pipes after repairs or maintenance – When pipes are drained, air can easily get in and form a blockage once the system is refilled.
Common Symptoms of an Airlock
If you’re experiencing any of the following signs, you might be dealing with an airlock:
No water coming from the tap
Intermittent or uneven water flow
Unusually low water pressure
Banging or knocking sounds from the pipes
Sputtering taps
Gurgling noises within the plumbing
These symptoms should not be ignored. Promptly addressing them can prevent further damage and restore your water supply to normal.
