      Explosions of air come out of all faucets occasionally and quite frequently, spewing water every where when it hits the sink. What causes this. I never know when it is going to happen. I’m hooked up to a deep well, submerged pump. Is it coming from under ground? Maybe a volcanoe in SW Georgia that has not yet been discovered? There’s an air buildup in the lines somewhere, but I can’t figure out why.

      Fresh water contains about 5% air by volume. As it sits in pipes and warms, some of the air leaves to form bubbles. At present, you have no place to collect and eliminate the bubbles from your system, so they collect and come out the taps.

      The well has a pressure tank joined with a pipe not far away from the well. The spigot at the tank has the same problem as every other water outlet in the system. Not to say your response is inaccurate, but I can’t see why air would be blasting right beside the tank, due to 5% of the air separating from the water. There’s no lines here for such air blasts to accumulate from warming. Do you have any other hypotheses?

      You have two types of anode in your hot water system depending on whether your water is “normal” or extra hard. if you have the wrong one for your water type then it will bubble away inside the hot water system and create the air you talk of

      Some wells have water sources that are high in gases, carbonaceous or ther. The gases is coming from the source and collecting, or as also suggested, encouraged to separate by the anodes. There is only one theory – air is coming in and collecting; you need to catch it and eliminate it. It seems the lines are the highest spot for the air to collect, an air collector before the lines are in order. The old tanks without the bladder let the air collect there first.
