little or no hot water flow

my 2006 winn journey developed a no hot water flow so I checked the water heater which was full of piping hot water pulled the inspection covers on the water heater found back flow preventers which I replaced still had no hot flow was directed to work the hot water bypass valve open and closed and got hot flow which stopped as soon as I got lathered up in the shower does the hot water bypass valve need to be replaced and if so has anyone out there ever replaced one and any suggestions to make the job easier thank you all

    the only valve i could find on the water heater was on the cold water inlet and was told by a R.V.parts man that it was a back flow preventer which i replaced i looked but could not find any kind of valve on the hot side of the water heater

    NO flow of HOT water thru hot side of faucets/shower.......check valve on water heater outlet stuck closed/jammed/clogged. ALL hot water comes thru it>


    Luke warm/cool water flowing out of hot side of faucets/shower....then water heater bypass valve is open or leaking thru enough that cold water is going into hot water line making it luke warm/cool (check valve on hot out closes/reduces flow due to cold water flowing into hot line)

    No hot water flow thru just one fixture......local problem with that fixture
