The personal observation of what is inside the tank that comes out when drained is enough to make a believer. It is not only tank maintenance, it is water maintenance. The tank is designed to extract hot water from the top and it is natural for the sediment to settle to the bottom. However, mixing of the layers is occurring.
I actually had difficulty in draining my tank (First time in 12 years) due to the thickness of the sediment clogging the small gate valve. Actually had to open water inlet valve and close inside faucet to pressurize tank to expel the sediment to get the process to start draining. That issue and cautions of drain valve leaks persuaded me to change drain valve to a 3/4 inch ball valve . That will make future draining a snap.
