I have a home that is on a joint well system. (A total of 5 homes) I have a fairly constant gurgle in my interior pipes. It seems to be worse in the spring and summer months. I reside in Wisconsin. It is not a banging but a very annoying gurgle. It also seems to be more prevalent around the water softener unit. I also wish I had greater water pressure. The home is about 25 years old.

You may need a check valve where the main line comes into the house because it sounds like there is some air in the lines coming from some where possibly the well pump is sucking air. You could also have water draining back in the lines with air.

Also try turning on all the faucets in the house on for a while to purge all air out of the lines.
