I bought and installed a 40 gallon water heater tank last summer and
the drain valve is some kind of a cheap plastic knob that won't turn
easily and if it did it might shoot hot water out 90 degrees and miss
the catch bucket. (My old tank was easy to draw 4-5 gallons a month.)
I asked the salesman about the drain faucet and he said all the models
they sold have the same kind of drain valve. Anyone give me the
proper procedure for flushing the tank? Will this make any difference
in the long run? Should I turn off the gas, allow the tank to cool
and hook up a hose leading to the outside? TIA
