All of the sudden, we can't turn our Symmons shower fixture to 12 o'clock. It stops around 10 o'clock in it's off position now. We've noticed that when we turn the shower on lately it makes a really loud noise in the wall and it almost has a delayed start to the water flow. What could be going on?
The only things that have happened lately is that we used our gas heat for the first time of the season and we had our boiler cleaned. Not sure if any of this has anything to do with it.
