Thanks Twisted Reptiles for taking the time to respond.

I tried to reach in and push the heat tape back in place but my arms aren't long enough - LOL.

So, if I understood correctly, I can put aluminum tape on the edges to prevent the tub from rubbing on the heat tape - correct??

I am not quite understanding where you want me to affix the probe - can you try to explain it again.

Thank you sooo much.
