Water gets into the node and the heat from the exhaust gases turns them to steam. The bang is the steam changing back to water when pressure forces it out of the node. Vinegr will not cure it and anything stronger may damage the tank or you.

If I was not sure before I am now, 4th year needs a 5th year. The popping sounds you are hearing is directly related to the sediment build up at the bottom of your water heater. It needs to be drained and the sediment needs to be removed. Good Luck, Bill The Local Plumber Tustin, California http://www.TheLocalPlumber.com
