Draining Water and Assessing Drain Valve

What happens here

The presenter uses a flathead screwdriver (from a Milwaukee multi-tool) to open the existing drain valve on the water heater. He observes that the valve is leaking and doesn't close properly, confirming its need for replacement. A garden hose is then attached to the drain valve, directing the draining water to a nearby floor drain. He intentionally leaves some water in the tank to provide stability, which will be helpful when removing the anode rod that might require considerable force.

Goal: Partially drain the water heater and confirm the need for a new drain valve.
