So my shower pressure dropped off significantly two months ago. Single knob control. Occasionally, the pressure would be fine for a single shower or a day or two. Sometime the pressure would be good, I'd turn off the water and when I turn it back on the pressure is low again. Sometimes recently when the pressure is strong, there will be a an audible 'clank' in the wall with the faucet and the pressure will drop.
What the heck is going on?
