I have not flushed my water heaters since they were installed 10 years ago. Thought this might be a good time to do it. The heaters are doing fine.
I googled for this subject and was instructed to turn off the gas and the cold water inlet valve, open the pressure valve, connect the hose and open the bottom valve..
Is all this commotion really necessary? Why can't I just turn the gas down to "Pilot", connect a garden hose to the valve at the bottom of the heater, and open the valve?
