Sam, did you take any pictures or videos of the repairs. I have some leaks and the sides appear to be delaminating. I was thinking about repairing them but I am curious as to the construction and what the best way to “peel” the siding off.
I removed my previous suggestions after I took a look at my water system and realized I was wrong in how I thought it was set up. Hopefully no one had a chance to read it!
My apologies to all.
