    John is right, use a slotted screwdriver, not pliers to open the valve. The spigot is the same as for a garden hose, in case you didn't know.  Obviously, you turn off the electricity or the gas supply before opening the valve and I always open the pressure relief valve to let it drain faster.

    Counterclockwise to open.

    Turn the knob or use a screwdriver if it is a slotted stem.
