Hello, Thanks for being here. I am working, in a small town of 200 or less, on a restaurant addition. The city only Provides a 3/4" water line to the old building. In the new building however there are 6 fixtures that require 1" Line ran to them. I was thinking that I should run a 3/4" line off of the old building then a check valve then into a 30Gallon Pressure tank(like you would use on a well), then take it to 1" from there. Would this work? What would you do in this situation? Thanks in advance, Justin.
