I have a 2005 state select hot water heater. We had no hot water this morning. The pilot was out.. I tried to start it but it doesn't even try to light. When I take the pilot cover off water drips out and I can see about an eighth of an inch of water in the bottom of the tank. I also see a damp sticker on the upper part of the tank with a small rust line... just below what looks like a water line coming from the tank. What do I do?
