I have a blue baron 47xl had it for a few years now never had any big issues. This year is the first season I have started to winterize it… now I have had nothing but headaches. Now I seem to have no water pressure. I was doing a tile and grout job. Lost all water completely. Brought it home set it back up to trouble shoot. Everything was working fine. Then yesterday I had one small job. Two bedroom carpets. By the time I was done I barely had 200 psi of water pressure and leaking from my hot water line going to my heat exchanger. I replaced the line. But wondering what else can be done. Sorry this is so long I’m desperate for advice and wanted to make sure I have as much info as possible
