Thanks to all for the ideas.
This is 1 1/4" ID reinforced PVC
flexible tubing - the stove idea would work great for smaller stuff. That, and I don't have a stove. Plus it's installed on a tank now
I'm thinking about a quick fix - a 1 1/2" PVC
pipe on the OUTSIDE of the tubing would do the trick, and take seconds to install. Over time, I'd guess it'd straighten itself out.
If that fails, I'm going to try the hair dryer idea first. Then I'll borrow a heat gun somewhere if that doesn't do it. My sump socks and brackets won't be in until Tuesday, so I have a few days to mess with it.
