Bleeding pipe method involves opening up all the water outlet units inside the house so that the air gets released. Turn off the main water supply valve to the house. Now starting from the faucet closest to this valve, start turning on all faucets around the house. Let the water run out. With it will the air be released too. You will notice that initially the water comes out in spurts and in severe cases, you will also feel the air gushing out.
Open you the showers. Flush all the toilets twice. If you are worrying about water conversion, place tubs under each faucet to save the water and use later. You also do not have to turn on the faucets fully. Just do it half so that less water is wasted. Let the water run till the sputtering stops and the water column is regular. This means that the air has been driven out.
Start turning off the faucets in the same order as you opened them i.e. start with the one closest to the main valve. Be on the alert for any more creaking noises. If there are you will have to look for other methods like installing a T-joint at the highest point of the plumbing system. It is better to call in a plumber if the problem is not solved by this bleeding pipes method.
