First, to describe my tub/shower it is a one handle, one spout type setup where you pull up on the knob to direct the water flow to the shower (typical setup).
Recently I noticed that when I go to fill my bathtub the water pressure is significantly less than it used to be and it takes much longer to fill the tub. The hot water is also not as hot as it used to be when I turn it completely to the hot side. However, the shower does not seem to lack in hot water (it feels like it gets hotter than the bathtub) and the water pressure does not seem to have changed either. Granted the shower always had excellent water pressure so I am not sure if it just went from really strong to just strong.
About a year ago I replaced the spout because the knob to direct the water to the shower wasn't working (when I moved into the house). Also, I don't think there is a leak because I have gone to the meter when I did not have any water running and it did not move.
I am not really sure where to even start here, any ideas?
