Good morning everyone. This is my first post. I have a lot to learn. Thanks for your help in advance. So,,,, here I go. I have almost no water pressure. Everything is old and outdated. A 1 -3/4 well pipe. I can only imagine how much crap is built up inside the tip. Can I reasonably put a 2" pipe in. Should I update the tall tank. The one under the pump is not connected. Is the small tank on top of the pump only to increase pressure. Once again thanks for your help!
