Doing my spring cleaning and am very satisfied at how little there is to clean out of the tubes.I probably don't have to clean them but I will.The only real problem I have is it looks like I have to replace my anode rod.I will be sending in another water sample and see what they have to say.The other problem is my gaskets stuck to the steel.Heaterman any tricks for that? The inside of my tank looks like day one.
