Hi, new to this forum, but nice to see other owners issues and upgrades. We have a 2016 Jayco Seneca HJ, our Girard has failed(cracked copper line). Has anyone here replaced them themselves? Is there enough slack on the inlet/outlet water lines as well as the propane line? Ours is housed in one of the black bay boxes behind our generator and I can’t see any lines going to it. Do I have to remove the bay box? I want to do it myself, retired military engineer, because the shops around here want close to 2K for installation. Thanks for any help on this situation.
