See below for a visual illustration of a gas water.
The rusting process can be slowed by regularly draining and flushing out the water heater but if the bottom is already leaking it s time for a new water heater.
All water heaters have a drain near the bottom of the unit so that the tank can be emptied before removal or during routine cleaning of the tank itself.
