Are all shower faucets heat regulated?
In the winter the shower water gets cold after a shower or two. While I was away on a trip, my spouse had the water heater replaced but it had no effect on shower water temps. We have very mild water and don't get a lot of mineral build-up in the pipes or water heater.
The clown that replaced the water heater now wants to rip open the shower wall to replace the "heat regulator" but this is just a basic 15-year old Moen shower faucet, the kind that building contractors often installed inexpensively i moderately priced track homes 15 years ago. It's not one of the fancier thermostatic models.
What are the odss that there is some kind of water temperature heat regulating device in the shower faucet wall?
