hi all. i'm trying to make some fixes around my mom's house and came across a problem that i imagine should be rather easy to identify for someone who is smart about this stuff (i.e. not me
one of the bathroom sinks upstairs gets essentially no hot water. the shower in the same bathroom gets hot water pretty well, but there's basically none coming from the sink - even when only the hot tap is on for a few minutes, the best i can get from it is something that is only *slightly* warmer than the cold water.
figured i'd just adjust the hot water valve under the sink and call it a day. but the thing is, i'm totally unable to turn the knob on the hot water valve under the sink. it won't turn either way - left or right - at all. it doesn't look rusted, and i even unscrewed the handle to see if there was some sort of blockage, but there doesn't seem to be. can't tell what's going on - basically the knob just won't budge. anyone experience this?
