Removing Old Heating Pad From Fresh Water Tank

Question

Question:

My old heating pad is defective and I want to install one of yours in place of it. I tried to remove the old one and gave up. How do I remove the old pad from the tank? Is there a procedure or chemical I can use? Also, can I just install the new pad over the old one? That would be the simplest solution. Thank you.

You do not want to install the pad part # 277-000163 over the old one because the new pad would not properly sense the temperature of the tank so the built-in thermostat would not work. You could use some rubbing alcohol to possibly dissolve some of the adhesive on the back of your old pad.
