Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial answer doesn’t answer your question then let me know and we can continue our conversation.I'm assuming you have a well and you're referring to the holding tank. There's nothing to be concerned about. The click is simply the pressure switch closing. It's normal for it to click. How loud the click is isn't an indication of a problem
Then you need to fix the leak. If there's only a short time between clicks then your tank probably needs to be replaced.
If it's clicking fast that's an indication (short cycling) that the tank has failed and needs to be replaced. Like I said before it's the pressure switch that's clicking.
By far THE most common reason for short cycling is a failed tank. Take the handle of a screwdriver and rap the tank top to bottom. The top 2/3's should sound hollow. If it doesn't the diaphragm has failed or the tank is water logged if you have an old style tank. If you have a diaphragm type tank it will have to be replaced if you have an old galvanized tank then you can drain it to recharge it
If the switch was clogged with sediment it wouldn't behave the way you describe. You can take it apart and clean it out if you like but it's not likely to solve the problem as you describe it
I've already told you what the problem is, a failed or water logged tank. The holding tank is never empty. It's not there to store water it's purpose is to provide a cushion so the pump won't short cycle, which is what you're describing.
