Atwood Water Heater
1983 Excella rear bath. I have a water heater I drained the other day. I noticed the drain plug had quite a bit of sediment on it. It looked as if though it had a element on it about 3 inches long completely covered in sediment. The drain plug was a simple pipe thread plug nothing fancy. My concern is. Do I need to replace this? Was there ever a sensor or element or has sediment grown on it that much. Kinda hazy I know but this is all I have to go on. Thanks for your input.
