Thanks for this scarce info. I have been buying local and have zero confidence that my expensive shipped in water isn't going to leak out. I heat the tubing and double clamp and still it drips. Prior to learning the heating process the fitting would blow off and I paid hundreds of dollars for additional water deliveries. I am currently replacing as much of the poly/barb fittings as possible to save my water. I will be hard pipe plumbing. I wish I had confidence in the poly science as it seems the perfect solution, until you see it fail.

Exactly. I'm glad we could help. Going over to pipe (rigid or flexible) is probably the best solution.
