The quickest way to remove an air lock in your water pipes is generally to bleed the affected pipe by turning on the tap closest to the suspected air lock and letting the water run until the flow is smooth and consistent. This forces the trapped air out.
Understanding Air Locks
An air lock occurs when air becomes trapped in a section of your water pipe, preventing water from flowing freely. This can manifest as sputtering faucets, reduced water pressure, or a complete stoppage of water flow.
Steps to Remove an Air Lock:
-
Identify the Affected Fixture: Determine which faucet or appliance is experiencing the reduced water flow or complete stoppage. This will help you pinpoint the area where the air lock is likely located.
-
Turn Off Other Faucets: Close all other faucets and water-using appliances in your home to maximize water pressure to the affected fixture.
-
Turn On the Affected Faucet: Fully open the cold water tap on the affected faucet. Let the water run for several minutes. The increased water pressure may be enough to dislodge the air lock.
-
Try the Hot Water Tap: If running the cold water doesn't work, try opening the hot water tap on the same faucet. Sometimes, alternating between hot and cold can help to move the air lock.
-
Lower Faucets/Garden Hose Method: If you suspect the airlock is in a higher part of your plumbing, connecting a hose to a lower faucet (like an outside spigot) and then connecting that hose to the affected higher faucet can create a siphoning effect to pull the air out. Ensure a tight seal when connecting the hose.
-
Repeat as Necessary: It may take several attempts for the air lock to be completely cleared.
-
When all else fails: Contact a plumber!
Prevention Tips:
- Avoid sudden pressure changes: Be mindful of significant water usage events, especially if you have older plumbing.
- Insulate pipes: Proper insulation can help prevent frozen pipes, which can contribute to air lock issues when they thaw.
By following these steps, you should be able to effectively remove most air locks from your water pipes and restore normal water flow.
