Fluctuating water temperature
We had a Moen single handle Posi Temp valve installed in our shower about 4 years ago. Over the last year it seems as though the temperature is fluctuating on the hot water side. Some days the handle has to be all the way in the hot range, other days you can put it barely in the hot range, both getting the same temperature. The water pressure also decreases when it is way over on the hot side. I've removed the cartridge and cleaned it according to Moen's instructions, but the problem continues. We also recently replaced the hot water heater (for other reasons) but it has had no effect on the water temperature fluctuation. Any ideas of why this would start happening all of a sudden and is there anything to do to fix it?
