Hello All,

We've just moved in and I would like to drain the water heater. It was
installed in 2000, but the owner never drained it.

What is the safest way to do this without damaging the heater? Water on or
off? Pilot light on or off? Etc, etc...

Many thanks for taking the time to respond!

I would open up the popoff valve. It lets air in, thus letting the water go
out with more force, carrying more crud. I would turn the water on and off
SEVERAL times to flush as much stuff out as you can.
