A look inside a hot water heater

This hot water heater started to leak out of the top. Guessing that this is the anode to collect minerals.

Deposits found in the bottom of the tank they are a little bigger than a quarter.

Looking at the bottom of the tank.

Build up in the cold water inlet side.

 Almost all of the minerals out of the tank.

This is the tank with top removed and outer skin and insulation removed.
