I have a heater up against the toilet but it is doing nothing to defrost the tank itself. It is now full. I know how bad it's been because I have horses and one night their water heater went off and the fifty gallon tank froze solid by morning. Is there anything I can to to defrost this thing. The valve will open and shut but nothing is coming out. YIKES!

I would be very surprised if the tank itself stood up to the freeze.
I suspect that the tank will be cracked in a number of places.
Fiberglass replacements are available for both the center bath and full bath models.
