    Lukewarm hotwater on second floor (sink and shower) but other level hot hot water
    Recently our shower (shower tub combo) with separate cold and hot taps started only giving luke warm water. The same goes for the hot water in the bathroom sink. This is only in the second floor bathroom.

    On the mainfloor (Kitchen and batheroom) the water is hot hot hot... in the basement the laundry room is hot hot hot...

    I turn down the anti-scalding device so that is why the other taps are hot hot hot... I will turn back on the anti-scalding device but I thought it something wrong with the valve.

    Anyway I am confused to figure out why the shower taps and the shower and the bathroom sink only have lukewarm water but the other taps in the house have hotwater. For some reason either the hotwater is not getting drawn up to the second floor.

    Since the mainfloor and the basement have hotwater... I don't think it is the main mixing valve.


    The main line going up to the second floor is split to the sink and the bathroom shower and both are only lukewarm water.

    We have a 2-year old direct vent gas hotwater tank.

    I have some suggestions that it might be the shower valve and the cold water and hot water are mixing but that would not explain why the bathroom sink is lukewarm too.

    Any suggestions?

    Dear muskokie

    As you have hot water downstairs, the problem has to be in the line to the upper floors.
    Is the water pressure normal when you only open the hot tap upstairs?
    If not, there surely is some tap (nearly) closed in the line to upstairs.
    If the pressure is normal, the problem has to be in the anti-scalding or some mixing device in the line to upstairs.

    :)

    The water pressure is normal in both the tub faucets and shower head and the bathroom sink. There only seems to be an anti-scalding device right at the main line out of the hotwater tank.

    If it is not the anti-scalding divide and there seems to be no visible mixing device in the line upstairs... what else might it be? Would it be possible that both the tub and the bathroom sink faucets failed and need to be replaced? Which would be odd for this to happen at the same time.

    Thanks for your help

    Water heaters slowly build up debris and crude. This debris, when it breaks loose, can clog the valve that is open at that time. It sounds to me that your upstairs bath hot valves may be partially clogged. Before exploring this flush the water heater. Attach a hose to the drain spigot at the bottom of the heater. Direct the hose to a drain and open the spigot for 5 minutes or until the water is perfectly clear of all discoloration and debris. Once done shut the main down and open your hot valves in the 2nd floor bath. Tell us what you found.Bob
