Shower goes from scalding hot to ice cold with a slight turn of the knob.
I can't seem to get my shower temperature under control. The water often is extremely hot or ice cold. I can get it to stay at a lukewarm temperature for a long enough time to take my shower.
If it is too hot I turn the knob just slightly and the temperature will swing wildly and become really cold. The reverse happens as well.
I tried replacing the ball valve, seats and springs but there wasn't an improvement. I didn't see anyway to remove the socket so I could put a completely new or different type of valve in.
I have a boiler system without an external water take. The hot water is generated right inside the boiler. I know this is why the temperature can be so hot and if left at a high enough flow rate the hot water will run out. But I seem to be haveing an additional problem with the temperature swinging back anf forth with extremely small twists of the knob.
Could anyone provide any ideas about what the problem could be?
FYI, I recently moved in to my house so I only have a couple months experience with the hot water.
