How do you bleed hot water tank?
There is a safe and slow way to do it, by turning off the water to the heater and removing both vacuum breakers and then opening the drain cock to hot water heater you can now drain it, which can take about 1 hour. however depending where the hot water heater is positioned, lets assume above a bath or outside installation, you can turn the hot water off and open the flange on the face of the geyser and drain it in about 1 minute.
