During this morning's engine check water started leaking from the upper hotwater tank hose--drip, drip, drip. The hose's outer layer had split. I suspect that my back repetitivly pressing against the hose during engine check caused the fatigue failure. The hoses' damaged end was removed. The remaining hose was more than long enough, so it was reattached to the hot water tank.
Note to self: don't lean back so hard during engine check ;-)
