This is the second year I have lived in my 72 Airstream. I made it through last year without too much trouble but this year is a different story. I live out east on the plains from Denver and we had an arctic blast. -25 was the worst but went at least three weeks in the single digits. Now my black water tank is frozen solid. 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!
Thanks, Charlotte
