Jell substance in bottom of hot water heater
I am a plumber and work in the Chicago suburbs, almost every town has Lake Michigan water, I have noticed when I drain and clean out the bottom of the 100 gallon hot water heaters with my arm in the clean out whole there is very little mineral debris but a lot of this blue/grey jell substance. Everyone I have asked to explain what this is gives me a different answer, bacteria, diptube resin, byproduct of all the chemicals added to the water, etc.. Can anyone out there give me a firm answer as to what this jell stuff is? Thanks in advance, Mark
