I wanted to do some regular maintenance on my water heater today, but I'm unfamiliar with the drain valve on there. My last house had the common spigot type, where you simply hook up a hose and open the valve. I'm not sure what to do with this valve, and I don't have a manual. At first, I thought it was just a plug, but it looks like there's a hole in the middle of it. Can someone tell me how to drain the water heater?
Also, how often do you do this? I've heard every couple of months and once a year.
Ohbhhh....I hate that type of valve. Anyway, its left loose right tight, like all valves. It will probably be plugged with sediment, so shut off the cold supply, open it and clear it with a piece of wire or something to get it flowing. After its flowing well, put an air chuck on the cold inlet and pressure up the tank. 40# or so should be good on the compressor setting. Blow the tank dry. Then, hook the water back up and flush it for a few. Job done.
How often you blow your tank depends on your water. In some cases once a month is not out of line. Sandy wells are like that. Depends on your water.

Maybe you should re-read your post. Because that^^^ coming from a "plumber" sounds ridiculous and will get someone injured.
To speed up the draining, open the top pressure relief valve or open a faucet and leave them open when refilling. But before you start the drain, TURN THE ELECTRIC OFF AT THE BREAKER, or you will be replacing the rods. And actually it may be a good time to take a look at the rods to see how much mineral build up they have on them. Scrape them clean or buy new for $11 each at H-D, Lowes.
