Unfortunately, when an internal tank leaks, this isn’t visible from the outside. Most tanks leak from the inside of the shell as a result of age and deterioration. The external shell of the tank insulates the internal shell containing the water. Internal TankĪ tank water heater has two shells to complete its job. If the water temperature is set too high or water enters the system with excessive pressure, the heater’s pressure rises. Because there is too much pressure, the water escapes through any crack in the heater, resulting in relief from pressure. When there is nowhere for the steam to go, the water pressure becomes elevated too much. As the pressure builds, the water heater needs to release the steam.

There are two electrical elements in electric water heaters, one towards the top and one near the bottom, which heat water on the inside.
