I own 1 tap, and 0 dies.Ok, got the antifreze out of it and am sanitizing it now. Added water to the batteries, I think one side of the older one is fryed. Almost no water was left in it. Ill check it next week to see if its broken or just shot. Eaither way new battery in the future. Also, on the dumb things I did this year list. I put the anode rod in the empty water heater. Usally I stick a rag in it, but last year the threads were a bit rusty, so I put the rod back in and gooped it up with liquid Teflon. This was not a good idea, when I took the rod out of the tank, the whole rod was disintegrated, a white globby mess. So, i needed to clean the water heater out real good. Unfortunate, because the old rod was good. I wonder if it saved the tank from being rusted? Or why it happened. Knowing me, ill fo the same thing next year.....I forget lessons easily.
