no water is running my deep well pump kicks on every 15 min. it runs for 1-2 min when it kicks off then a noise like someone threw a ball against the house. can you help
Where is the noise coming from? The pipes, pressure tank, or starter box. I assume you have a submersible pump? If it is the starter box it could possibly be that your pump may be at fault pulling to much amperage and causing the starter box to make those kind of noises when it cuts out. Well pumps typically last for 15 to 20 years with the odd exception. Another thing to check is your pressure tank. If it is one of those old galvanized ones it needs to be charged with air regularly as they tend to become water logged giving you very little water in between pump cycles. Another thing you could try is cleaning the points with some emery on the pressure switch. They tend to become corroded and can cause problems with the pump operating at all.
check the back flow preventor sound like it might have trash and or build up casing it to stay in the closed position and when your pump turn off you hear that thud like sound due to the pump having to be slammed it reverse do to pressure build up.
it sounds like either your pressure switch is messed up or your pressure tank isn't working right
