First time poster. I have a 10 yr A O smith 40 gallon gas water heater. It runs the master bedroom side of the house. I usually flush once a year. I have never replaced the mag. anode. Right now I am turning the cold water off and opening a hot water faucet during the day to keep it from leaking on the top. Just visually looking; the top of the tank looks fine. The hot and cold inlet nipples look ok and I don’t believe water is leaking there. Everything I have read from previous posts seem to point to a new tank once you see leakage. (If I leave it on for 8 hrs the water puddles but does not run off the side) Should I remove the anode..check it..teflon tape it and re-tighten. I don’t want to buy a new anode until I know that I can stop the leak. Because in the end I may need a whole new tank.
Then try that. It may help. But you’re right: my experience is that when leaks develop on top of the tank around fittings that were sealed before, it’s the sign of the end.
