You don't need to drain it.
Turn off the water into the house, open the tub faucet and just drain the tank for a few seconds. You'll hear air being sucked into the tub faucet. You just need to drain the pipe where the fitting is.

You should have a water cut off on top of the water heater. Cut it off. Hook a water hose to the the outlet on the bottom and put the other end somewhere it doesnt matter if it gets wet, ( down drivewat etc... Open valve on bottom, Then lift the little lever on the temp/pressure relif valve, Its the thing towards the top, but still on the side, that has a 3/4" copper line coming out of it. That will allow air to go into the tank to help it drain, On average, maybe 30 minutes or less GL

many times while they take an prolonged time to empty it is by the fact a vacuum has formed interior the tank. it is in view which you haven't any longer grew to become on any of the nice and comfortable water faucets everywhere to enable air into the tank and a vacuum has formed interior the tank. to scrub out the sediment circulate away the drain valve open and activate the chilly WATER for a couple of minutes then turn it off and look ahead to all of it to empty out, then do it back, it could take countless situations to get lots of the sediment out, you will no longer get all of it out. i in my opinion do in no way mess with the spring loaded pop off valve on incredible of the tank, there is an extremely stable possibility exceedingly on older tanks that it will no longer close thoroughly, and then it will be needed to the two replace the valve no count if it is not frozen or changing the completed tank. ON previous TANKS it is often greater useful TO DO as low as attainable because of the fact they have A habit OF never working properly back when you have MESSED WITH THEM.

depends on the capacity of the tank , the size of the drain, and the piping that the water tank feeds. personally if the tank has a discharge valve. start by draining the tank for about 15min then shut the discharge valve to the tank and the drain, then you should be clear enough to change the compression fittings
