Excellent. Do you own the water heater?

I don't use shop vacuum. I also open the pressure relief valve and let gravity do the draining. I don't drain the entire tank as the water isn't dirty. I just drain about a bucket. Make sure you shut off the water supply and gas supply (or in pilot mode).

1 - turn off water supply and power/gas to water heater
2 - hook up garden hose to drain valve
3 - open drain valve and turn water supply back on to flush out crud in valve
4 - turn off water supply and drain tank
5 - open up a hot water faucet to let air in as water is draining
6 - after tank is drained open water supply to stir up sediment on bottom
7 - rinse and repeat (a couple of times)
8 - turn on water supply valve partially and flush tank out till water is clear
9 - close drain valve and open up water supply fully to fill tank
10 - close hot water faucet when tank is full and all air escapes

No shop vac in ever needed.
