      Do I have to disonnect COLD water supply to drain? I turned my electric heater off, loosened the ‘outflow’ pipe for air, and opened the drain valve, but no flow came out…. What’s wrong?

      hook it back up and turn the water back on. open the drain valve, this will force the sediment out of the way so it can drain. let it run full blast for a couple minutes then turn off the water and then open the faucets in the home to break the airlock.

      Greg, congratulations You just learned what a vacuum is in plumbing and why plumbers rely on vents to allow atmospheric pressure to be equal.
      In other words OPEN THE RELIEF valve or any hot water faucet to allow into this tank TA DUMMMMM
