We had a Rheem 50 gal 12 yr gas hot water tank for 6 years with no issues. We started having an issue around Dec where the water was cooling during a shower. The same coolness was in other faucets and showers. We replaced it with the same new tank a month later and found the same issue. There is no leaking, no change to shower pressure, no new building, same amount of people. No change to anything to do with our gas. The only thing that’s out of the ordinary, was that we had our gas furnace serviced shortly before the issue started.
Why do we not have enough hot water?
Would love to hear from someone.
Thanks for your time
