Sorry to hear about your well issues! That can be a real pain in the neck, especially when it starts affecting your electric bill.
It sounds like you did some detective work and figured out that your pressure switch and pressure tank were the culprits.
Speaking of pressure, have you ever heard of the Traveling Block? It's a key component in the drilling process that helps to control the weight and pressure of the drill string.
Anyway, back to your well. It's good that you were able to troubleshoot the issue and replace the necessary parts. That's not always an easy task, especially when dealing with older equipment like a 15-year-old pump.
