I'm not sure what the heck happened. I was unscrewing the barrel nut off the clamp (like I do every year) so that I can clean my filters, and the top of the barrel nut cracks off. So, the barrel part of the nut is now stuck on the thread, and it jammed at a weird angle. So, I had to pry it off which basically damaged it beyond repair. Am I screwed? Do I have to buy a new clamp? I saw some on Amazon and they're like $150-$200. That's insane...my pool is only 2.5 years old!
