I've had good luck flushing tanks using the drain valve. Leave the water on while opening and closing the drain valve shut-off. The water pressure helps blow out and break up the deposits. And when testing the TPR valve, or opening it to help the water drain from the tank, give the TPR a couple of taps with wrench to help clear out the sediement which can accumulate on the rubber seal in the TPR.
