On Elmer's Pipe. If you need something to last, buy his products. He makes good stuff, and he's there on premises making the stuff with his employees. I bought a piece for a reline and insert install last year and it was awesome. Easiest to work with, and by far, the most rugged piece of flex pipe I have ever laid eyes on. He has everything you'd need but it's not cheap junk. He's running a small business and has a payroll to make.
