Our hot water is not very hot. I looked at the heater and can't find a way to turn it up. Help? 2003 Starcraft.
  • yep, that's your WH bypass valve for winterizing. the WH's have a preset temperature.
    i guess you could use the bypass valve to vary it.
    i've never found any RV that had water that was too hot and needed to do something like that.
  • I think I figured this one out. There is a bypass between the hot and cold lines on the output side. It was turned on so I turned it off. I guess you could "feather" it to get the desired temp.
  • Is the water neater bypass on?

    Tried it on gas and also electric. Burned out electric element (from being on with no water in the tank) is very common and a in-stock part at every RV dealer because of it.

    Also see if you're getting warm water of the cold tap too. If the shower is turned off a the head it acts like a mixing valve. The outside shower is infamous for this and is usually locked in the lil' compartment.
