First post for me- Have a "never seen this before" question for ya: My daughter bought a model home about 7 years ago so the home is about 12 years old now. Just recently, the faucet in the master bath tub quit delivering "hot" water. The hot side is very warm (maybe 105 degrees or so) but definitely not hot .... never happened before. EVERY other fixture in the home (every sink, shower, etc) yields super hot water. The tub faucet is a Moen wide set with separate handles for hot and cold. I do not believe there is an "anti scald" device anywhere in the plumbing of this home.
The only situation I can visualize that could cause this problem is that there must be some (undesired) interaction between the hot and cold cartridges in the fixture; i.e., when the hot is opened it does something to let a bit of cold water out of the cold cartridge (even though the cold is "off") and it mixes to drop the temperature of the water exiting the faucet nozzle. I don't know how the cartridges are designed or if this is even possible but I can't envision any other explanation. This is the only fixture in the home that doesn't yield hot water when just the hot is turned on. (BTW- The cold side on this fixture works normally.) The tub fixture has worked fine for about 10 years and nobody has "messed with " the plumbing in any way. Ever seen this before? Is my logic plausible?
I'll try to post a pic of the fixture ........... just to show it is very ordinary/nothing special.
Thanks in advance for your thoughts; I am stumped on this one.
