The unit came with instructions on how to install on your own but am stuck on what parts to get and where. Because the existing copper pipe will not bend to reach the unit we will have to cut and flare that line and add a shut off vale and new line to the unit. I am not sure what type of shut of valve I should get nor what type of hose to get from old copper line to the unit..... braided? Also not sure on what size fittings to get once I flare the copper line. What is the standard size of the copper lines in these old MH's? I have a few ideas but not sure I am on the right track.
