My main bathroom tub does not fill with hot water....but the shower stall opposite it (in our bedroom, but sharing the same wet wall) gets plenty of piping hot water. I am not a plumber in any sense of the word, so I am not sure what is going on. My suspicion is that there is some sort of safety feature on our bathtub faucet (Moen) which prevents the water from getting scalding hot. This seems to make sense as the presumed users of the tub would be children.
To compound the problem, we bought our house 6 months ago and the bathrooms are professionally remodeled---meaning that I am reluctant to tinker around/take anything apart unless I know what I am looking for.
Does any of this make sense?
