Hello . and thank you for the reply . I did the test of the cross connection . I turned off the power to the heater , and then turned off the water supply to the heater . Then I went to the first available faucet and turned on the hot side . It was hot for a few seconds and then started turning lukewarm as I said before . Then after a few seconds more , it stopped all together .
I have a small home , and only have 1 bath , kitchen , and laundry room . I also have 2 outside faucets , one in front and one in back . All of my plumbing is accessible from my basement , but I checked each one to be sure there were no leaks or anything running . I have been dealing with and trying to figure this out for a week , and it’s beginning to wear on me . There was absolutely nothing wrong with my hot water heater last Tuesday . I am not sure what to do next .
