I have a 1.5 year old HW heater, a home warranty replacement, it is set to run pretty hot (not scalding).. Over the last six months we have to turn our tub valve more and more to the hot side just to get comfortable shower temps. Sometimes it starts hot but gets cooler as we shower, and you have to turn it more towards the hot side. The tub valve appears to be an old cartridge style (I have not actually removed the face plate yet) from maybe the mid 1980s. We don't seem to have a problem getting decent hot water from our kitchen sink faucet. It is a small ranch house with copper piping, and no visible leaks in the finished tall crawlspace.
Do you think it is the cartridge or the relatively new hot water heater?
Thank you
