Clean Water Heater

I decided not to go with the vinegar and water procedure which would have required removing the pop-off valve to fill the tank.( No winterizing kit) I simply removed the nylon drain plug with my handy Camco wrench, drained the tank, got drenched, and squirted the sediment loose with my handy Camco water tank rinser. Next, I hooked the hose to the city water port and flushed the tank. I repeated use of the tank rinser I got a good quantity of white sediment out of the tank and onto the driveway. Finally, I installed a new nylon plug with Teflon tape and refilled the tank with pop-off lever open, when water ran out the valve I shut off city water and shut the lever on the pop-off valve. I ran the water heater on propane and water got hot with no weeping out the pop-off valve. I figured that the Atwood aluminum tank would still be in pretty good shape, glad it's not rust-prone steel.
