We bought our house in Feb 2004 and it was hit by lightning in jun 04. The lighting damaged anything that was connected to the electrical and phone system. Since then we have had problems with our well. The well pump circuit breaker has been replaced. Sometimes the switch will go off and we have no water. We go down under the house and reset it and it is fine, until the next time. There is no set time it usually does this but it is usually one time in a couple months. The well is a 1/2Hp submersible pump. Last July I had someone come out and look at the well. They pulled it up and determine the check valve was bad so they install another one. I have also installed a low pressure switch on it so it won't burn up the motor. Just recently we heard water flow very quickly under the house. I went and shut off the main water valve to stop the flow of water. It appears the water was flowing back into the well. This has happen before when the first check valve went bad. I then went into the garage where we have our water softener tank it was collapse. As if our well was pulling a vacuum and sucking in the water softener tank (not the brine tank). Do you know what could be causing this vacuum? These well problems are generally happening in the summer time, around June - Sept every year.
