pvc pipe
Posted by bob on May 02, 19101 at 11:35:42:
Recently I purchased several lengths of PVC pipe 1 1/2 inch, noting just the schedule 40 markings, I glued them up to my pool pump (outflow to the jets).
Afterwards, I noticed the markings saying "DWV- Non Pressure". Will this still work or do I have to cut out all the pipe and start over ??
I thought the "Schedule 40" rating meant that it would take 330psi (for 1 1/2 inch).
What's the difference between the two pipes???

thanks
