If you're going to continue to turn off supply and have a known leak, I
would recommend turning off or at least way down the water heater
setpoint so don't try to keep it at full temperature w/ no feed and
potential outflow--it's not good.


Umm, if the water is off, how exactly does the water flow out of the
water heater?



Um, Mikey, I know these guys are idiots for the most part, but....
If all the valves are off in the house and you turn off the main water
supply with the heater still going and the heater doesn't have an expansion
tank, the expansion of the heated water in the now closed hot water system
could blow out of the T&P.

I'm just sayin'.......:)
