: I recently drained and refilled my Hot water heater. I was told to do that every once in a while. Well, afterwards, the hot water pressure in my bathtub faucet was greatly diminished. Everywhere else, the pressure is just as strong, but at the tub/showerhead, the pressure is almost gone now. What could be wrong and what could I do to correct it? Sounds like maybe something from the tank maybe alittle of the dip tub has broken off and blocking your faucet..is it a single lever type shower valve? If so try shutting your water of and removing the cartridge or cartridges then with another persons help ask them to turn the water on slowly and allow to flush the lines.Good luck
