I decided, for the first time in years, to drain my 2 50-gal water heaters. After the water stopped draining, I turned on the water supply for a few seconds, and the 1st WH put out a good deal of small white sediment particles. After it finished draining again, I repeated this about 5 times. I then did the same with the 2nd tank (once the first one filled up).
It got me to thinking, though, that I wonder if it's really necessary to drain the whole tank? Could we, instead, just open the drain valve while the water supply is still open, and flush out the bottom of the tank? Or is it really necessary to have the tank empty?
Or does any of this do any real good?
