In order to use vinegar soak you have to pour the vinegar into water heater tank.
Remove the Pressure Relief Valve. Use a funnel and pour in 4 gallons vinegar (for a 6 gallon tank)....then reinstall PRV.
Open PRV via lever and turn water supply on to fill tank. Secure water supply and let PRV snap close when water runs out of PRV.
