Today's paper had an article about checking the relief valve on the
water heater, this link shows a "demonstration" of the power of an
exploding water heater...

Except they don't mention how to check it... Just lift the lever on the
valve/
Yeh, I made that mistake on my 12yo heater. Valve worked fine, but wouldn't
shut off.
