OK, here is the problem. I have a gas water heater (American H2O Heater) 50 gallon. There are only 2 of us and over the past few months I have noticed a dramatic decrease of hot water.
It never runs totally cold, but a constant adjustment has to be made at the faucets to keep the water warm. This is consistent at both showers and both tubs.
The heater is 9 years old and had only a 5 year warranty. Is there any troubleshooting I can do? No routine maintenance has ever been done on the water heater (at lest over the past 3 years).
Any ideas would be great, and thanks ahead of time.
