Model # MI403T6EN12
Water heater provided plenty of hot water for showers the past 10 years. All of a sudden, it now is a struggle to get through a shower with enough. Shower doesn’t have a mix valve, separate valves for hot and cold. I’ve checked the sink mix valves and they are good. I suspect the thermostat gas valve on the water heater isn’t working right. I’ll probably replace the water heater since it’s over 10 years old, but wanted to ask what else I can check or test?
Question # 2… Is it possible for a dip tube to be installed on the hot water outlet of the tank? I ask because while looking at the unit, I see who ever installed it has the cold supply hooked to the side labeled for hot. They did cross out the hot label and wrote cold. Just curious if they installed the dip tube on that side so it would work correctly.
Thanks in advance for your help!
