One house I own, the water heater drains just fine. Put a hose on the

a slope, so the gravity helps. But my other house in Florida is
another story. I can't get the WH to drain. What am I doing wrong?

Hmm,
Gravity? How about openning a hot water faucet at the highest
locationin the house for venting for a stater.
