You're welcome! I like to learn about things I don't know about yet too.
I asked him what I should watch for (if it's the pump) and he said if I notice that the water pressure is low and see that the pressure gauge is staying below 30 (I think), to cut off the power to the well and call someone in.
The reason he gave is to keep from damaging the well itself (the water space underground).
I asked him if water wells need any type of yearly tune-up or anything and he said no. As long as it's running good and properthen all is fine. He said well systems are not like cars where they need regular service.
Hope this helps you someday. It's a learning curve!
