WHY DOESN'T IT LEAK UNTIL REHEATED? (this could just be our
interpretation. I had theorized that residual water is draining out
from the insulation, but it stops dripping while the unit is drained
and for several hrs after refilling).

Thanks for your advice.




Because the tank expands a bit when the water's hot. Loose pipe somewhere
or T&P valve?
