Good point about the hot water. better safe than
If you relieve the pressure, then it will just glug out a little like Frodo said.

pretty sure I said close the faucet as well. But that important detail can easily be missed in my post.
Frodo's comment was more informative as to why you close it.

when I have to pull a plastic nipple on old a heater because it doesn't drain or is leaking I have a rag, a sturdy screw driver and a hammer nearby.

If it's cooking yes. You would want to shut the water heater off first so it's not cooking
