Hello All. I have a Rheem 40 gal electric water heater, 6yrs old and thought I would flush it, Every instruction I have read says to turn off the water supply and the power-----Why? I can easily cut the power, no big deal. BUT why do they advise to turn off the water supply? Itseems to me I would want water flow to help the flush? and if I can leave the water supply on, what is the danger to leaving the power on? Thanks All
