What Causes a Water Heater to Leak From the Bottom?

What causes a water heater to leak from the bottom is usually caused by cracks in the tank over time. The first thing you need to do is inspect your hot water tank for any cracks or damage. If you find that one of these cracks is larger than six inches in diameter then this will more than likely cause a hot water leak from the bottom of the tank. There is another way that you can prevent a hot water leak if you are using an older model of hot tub heater.
