The key element you need to displace the water with air. I really like "Old and Soft" about the straw. It is also like doing dishes, and you lift an inverted glass full of water out of the dishpan. The water in the glass is above the dishpan water level until you get the rim about the water level, and whoosh, the water escapes.
Two easy ways to drain the water heater:
- When I remove the drain plug for the water heater, I open the pressure relieve valve.
- If I open the two low point plumbing drains, I commonly open a faucet (both a hot and cold water). This allows air into the system to displace the water.
Key, you need to get air into the system
