well system pressure stops after a couple minutes
I don't quite understand what you are reporting. When you said Recently, "I have noticed that pressure will start then stop for several seconds and return. Tank pressure is within the required range", what do you mean? Are you speaking of the pump or the flow of water?  You said that the water pressure stinks, so I have  to ask "what is the water pressure"? What is the pump "on" pressure and what is the pump "off" pressure? The tank does not control the water pressure or the amount of water delivered to the faucets. How much water can you use before the pump cycles? Your answers will help us give direct answers to your problem. How old is the well and what type pump do you have? Is it a submersible (down in the well), a jet pump (above ground), A rod pump (very old type), or something else? Your problem could be any  number of things and a better explanation of the existing conditions is needed. Many of us lived with water wells as have I. Please respond.
