So I go to drain my hot water tank at its one year anniversary and nothing comes out of the drain valve - well a little drip here and there maybe. I did all the right things I believe, turned off the cold water, opened up a hot water tap, hooked a garden hose to the drain valve (cheap plastic valve that I wouldn't trust for anything).
So I assume its clogged with rust, I have galvanized pipes for my cold water supply and I know they are at or near the point of failure and all the rust that comes with that (I have the blue PEX chilling in the office until I have a chance to start removing the galvanized). So I'm wondering does rust form a solid mass eventually or can it be loosened up enough to let the drain do its thing?
