Was wondering if anyone has seen this before. Just opened the cabin for summer - we blow out all the water lines when winterizing. Primed the pump, opened all faucets and slowly opened the main feed. The hot water tanked filled and all air was released from the lines. Everything was fine and there were no leaks.
Then I turned on power to the hot water tank and there was a leak in a pipe underneath the floor. Just to be sure what was happening I shut the main water supply and power to the hot water tank and let the water tank cool for a day. I repeated the process (without power to the water tank) and all cold and hot lines worked fine with no leaks. Then I applied power to the hot water tank and sure enough the leak started again.
My thinking is that there is a weak point somewhere that expands when the hot water hits it. Seems odd though. This weekend I have to remove the shower stall and cut the floor boards to get to the problem. Any insight would be helpful and ways we can prevent this from happening again. Thanks!
