Re: What "Schedule" Pipe for Pullup system?

Ian, I was going to attempt to calculate this for you this morning, however, according to my pipe book, 1" doesn't come in Sch 20. Now, I'm not saying my books are infallible, but we don't use 1" Sch 20 for anything. It may be used by the firewater guys, but not for civil/process engineering.

To cut to the chase, I've run the numbers on sch 40; use the sch 40/std wall pipe and you'll be fine.

I am NOT a professional engineer...keep in mind you are taking advice from someone on the internet. no liability, legal recourse, hurt yourself at your own risk, etc.

Does anyone know if this will be sufficient for a system that will have about span 3.5 feet between supports??
