It is only necessary to open the faucets a half turn to allow the air in your pipes to escape. After you turn on all the cold and hot water faucets in your house, you should also flush your toilets to clear out the air trapped in your pipes.
Start with the faucet that's closest to the shutoff valve and work your way to the farthest faucet. Make sure you open each hot and cold faucet about halfway to let the air run out. Remember to flush all the water out of the toilets, too.

Use a Drain Snake : If the plunger doesn't work, try using a drain snake, a long and flexible tool that can be inserted into the drain to remove blockages. Turn the snake clockwise to loosen any debris or air that may be trapped. Check Your Vent Pipes : A blocked vent pipe is another cause of air locks in waste pipes.
A mix of baking powder and vinegar will do the trick. Simply pour a jug of boiling water, followed by the baking powder and vinegar. Insert the plug and leave for ten minutes, before finishing with another jug of hot water.
After you turn off your mains water system and drain excess water from your residence, turning the water back on and running your faucets and house appliances that use water can remove air bubbles from the pipes.
If you have any leaks in your pipework, air can enter the water lines through them. Any such leaks can throw your home's water supply network out of balance, causing significant water pressure problems. Also, the amount of air in your plumbing system will continue to increase, worsening the noise and water flow issues.
Flush cold water.
Run all cold-water faucets on the property beginning with the faucet closest to the water line. Let all run at the highest flow (or fully open) until water is clear and temperature is constant. Then turn off all faucets in reverse order.
While these sounds can be scary and seem like serious issues, the cause is usually quite benign. Most often, a loud sound coming from your pipes is caused by trapped air. By turning off your main water supply and running all faucets for 10-15 minutes, you force any trapped air through your water pipes.
Relieving yourself as soon as you need to pass gas or have a bowel movement, walking, applying heat, and taking deep breaths can all help relieve gas pain. You may also find OTC remedies and supplements helpful. But talk to your healthcare provider before taking them to be sure they are safe for your situation.
The Showerhead Method
Locate your water heater and turn off the hot water outlet. Return to the shower and turn on both hot and cold water faucets. The plastic bag seal will create an increase in pressure, which should ideally travel back down the pipe and help bust that air lock.
Will an Airlock Eventually Clear Itself? Sometimes, small airlocks may clear themselves as water circulation continues with one or more radiators. However, larger airlocks often require manual intervention, like bleeding the radiators or using a hose to release the trapped air.
The trapped air can cause pressure build-up, which can lead to leaks or bursts in the pipes.
Make sure you achieve a good seal to prevent pressure from escaping. Turn on the hot water for a few seconds, then the cold water, and keep both on for about a minute. Now, turn off the cold water then the hot water tap. Water will fill up inside the hose and pressure should build up to break the airlock.
In worse cases, the air pressure can cause water to shoot from the faucets. This trapped air can even cause loud thumping sounds when the water is turned on. To remove the air as well as get rid of any noises, you should know how to bleed plumbing pipes.
Install an Air Vent: Attach an air vent to the pipe to release trapped air from the system. Use a Drain Pump: A drain pump extracts both air and water from the system to clear the pipes. Open and Close Valves: Sequentially opening and closing valves at different points can help purge air from the system.
When pipes or vents become clogged or damaged, they create negative air pressure. Negative air pressure causes a toilet to bubble when the shower is running. The negative pressure pushes air back through your plumbing, causing the bubbling sound you hear.
