So I have a 15+ year old water heater, bought the home recently and now the waterheater makes a "rock popping" sound inside the water heater after showering or using water for a period of time. I would like to know what exactly I need to do to drain it to get out the sediment in the unit? I have a State Select modelPR640NBRI Serial Number: 802408835 (cannot find any manual or instruction online at all) and when I bought the home obviously 15 + years later the manual and instructions are gone.
May I ask what I need to do step-by-step? I know the basics of needing to hook a gardening hose, shutting the COLD water valve off and (maybe shutting the gas off??? is that necessary?) I just need help if possible guys. Should I wait hours to drain it, etc.. and how would I reignite the pilot light once I'm finished if I need to turn the gas off. I am attempting to add some images to the post also but am quite unsure on this process. I just don't want to be scalded with water or water heater explosion while I'm using it :hide:
