i have a well, with a jet pump and a expansion tank. I dont know the particulars about the size of the current components. It appears that all plumbing has been bastardized. This is for a two family house, that has a total of 5 bedrooms, 2 baths and clothes washers on both floors.
My question is, if I were to replace the leaking expansion tank with something else, what should i replace it with? How do you properly size this?
