I have a submergeable pump well system. Down in the basement is where the line coming in leads to a air tank pump. the system uses air pressure to pump though the line from the tank. When the lines need more pressure the tank pump kicks on and once pressure to about 80 lb the unit kicks off until 20 lb pressure. The problem is while in the shower. I can feel a 1 second surge when the tank kicks on. While the pressure is rising until kickoff my hot water is ice cold. The tank kicks off and them I am back to warm water. How can I remedy this? mek@duo-county.com
