Then I would disconnect the hotwater output on top of the water heater and open all the hot water faucets in the house and blow air into the flex line on top of the water heater. I am assuming it is a copper flexible line, some are hard plumbed, the air should blow out almost all of the water from the lines. There is another way this can be done, there is a special spring loaded check valve that can be buried in the ground and surrounded by gravel, this device opens up and drains water when pressure is relieved, or at about zero psi. These were invented for underground sprinkler systems, but can be used for other purposes. About the partial vacuum, the system has trapped air and can be relieved by opening the faucet that is the highest of the bunch prior to draining, of course this is with the water pressure turned off.
