I had visions of getting my watering done with the water from the tank, but no go. I can't get it to drain at anything more than a trickle.
Sounds like an air lock.
You need to introduce air into the system.
Open a faucet or two. Open the T&P valve. Disconnect the flexes on top.

You will need to break the vacuum buy removing incoming and outgoing connections at the top of the tank.
It still might be slow due to build up of sediment at the bottom of the tank, especially with the OEM gate valve.
This was after disconnecting everything but the drain hose.
The problem ended up being stupid . . . I couldn't get the sprayer off the end of the hose so I had it at the far end locked on open position.
I gave up with about 1/3 still in the tank and used the hose to water, at which time it became clear the sprayer head had clogged with junk.
Will have to take another shot at it tomorrow night.
