I'm experiencing a problem in my current home that is eerily similar to one that occurred many years ago at my mom's house. Both involved Moen single handle/single cartridge tub/shower valves. Mom's was definitely NOT pressure balanced while I don't believe my current home's is either.
The problem is is that over the course of time, you have to keep adjusting the valve more & more to the HOT side in order to achieve the desired shower temperature. Water pressure was NOT affected either time. At mom's house, hot water eventually became unavailable until I inadvertantly made a big mistake that cleared it up! I figured it needed a new cartridge, so I replaced it. It cleared up for a while, but within a few weeks it was back. Once again, I go to remove the retaining clip & cartridge, but I apparantly forgot to turn off the water, and the cartridge shot across the tub like a bullet into the tile wall, where it luckily didn't damage the tile (or my narrowly-missed head!). After I scrambled to turn off the water & stop the deluge, I reassembled everthing & the problem never happened again.
