Hot Water Heater Mineral Buildup - Removing Encrusted Element
In the process of doing some hot water heater maintenance, I discovered the lower heating element encrusted in mineral buildup. There is so much buildup that I cannot pull the element completely out of the tank to properly clean it. I was thinking about dumping some vinegar into the tank and let that dissolve the buildup enough to get the element completely out. Is there any reason I shouldn't try this technique or does anyone have another suggestion? Where is the best place to get a replacement o-ring for the element? I believe the element is still good after testing its resistance with my multimeter.
Also, unrelated to the water heater question, is it OK to connect PVC to ABS?
