I agree- the way I understand it, the glass lining is only another line of defense against corrosion and years of exposure to hot water will very slowly dissolve it and also that virtually every glass lined tank has some imperfections present in the lining that leaves very tiny areas of exposed steel and of course (as mentioned above) there could always be a crack that would compromise the protection offered by the lining.

I agree too; I should have written there is not AS MUCH need today for sacrificial anode rod as before glass lining. I think I must have gotten a tank built on Wednesday and Bubba was off sick that day so he didn't toss it into the shipping truck. Knock on wood!

Depending where the water heater is located, quick hands and a shop vac can eliminate the necessity of draining the tank!!
Works better with the short elements. Then there is the element that is broken with it essentially being a barb on the fish hook. It won't come out, lime has washed into the threads, and you can't get it back in the hole...o dear.
