The only thing I can think of that causes the noise is that the inlet into the house (from the well) is across the room (~18ft) from the pressure tank. I'm thinking the length of copper pipe causes some cavitation...? We have no problems at all with water flow or pressure. I've looked and can't find the make/model of the pump. The noise is just dang annoying! Is this anything that I can fix somehow or is it something that I just shouldn't worry about? Thanks for any help you can offer!
Sometimes they get loud when they are old.
The bearings get worn.
Try a new pump or, live with it until it dies.
