Thanks for the reply. There's 3 valves, one for cold water, one for hot
water, and one for the dishwasher. I'm guessing the dishwasher one is
connected to the hot water one, because when I push in one of those,
the other moves in too. I could turn those handles fairly easy, but the
cold water handle won't turn at all. This is an old apartment building,
so I'm guessing that one is corroded. But shouldn't the hot water and
dishwasher work since I can turn those handles? Or are they somehow
connected to the cold water valve?
