I used one of Harbor Freight's vacuum pumps to vacuum drain my former GMC's (both Avions) water system. Attached a fitting to the lower port on the hot water heater, attached air compressor to vacuum pump and applied power. Did a great job pulling all the water out of the system, using negative pressure. No outside force on any fitting, other than air flow from the outside.
Used during many years of outside Winter storage in Virginia. Not much need, here in Lower Alabama.
