NO hot water in master bath
I moved into my home built in 2005 about 6 months ago. When we moved in hot water worked well to all parts of the house. Just recently I noticed the master bath tub has no hot water comeing out but everything else in the master bathroom works properly. The bathtub is only a tub with no shower and has one knob to control cold to hot. It seems that the faucet has no hot water coming out at all. As the knob goes from cold to hot the water slows and then when the knob is turned all the way to the hot side the water goes down to a trickle and never gets the least bit warm.
