    Very littles volume on Hot water at sink ?-gctid809211

    The boat is connected to city water. Weather on city water or the tanks by pump , there is very little flow on the hot water side. Cold flows nice ?? Clogged hot water heater ?

    TIA Kevin

    Sounds like you have a clog in the hot water system. I would turn the water off then disconnect a hot water line somewhere where the water can be run into a milk jug or something like that. Have a helper, grandkids are hand at this point, turn the water on and check the flow. You may have to do this a few times before you find a line with full flow.

    You might even want to start at to hot side of the water tank because it's sorta easy.

    One thing for sure, you are going to get wet, so be prepared.

      First thing I would check like a house - With the water pressure on at the dock - pull the handle on the hot water relief valve and back flush the heater into a bucket. See if there is any debris? Once you flush about 5 gallons - check the hot water pressure again.
