Ray to be honest I don’t know. Never looked into it. I use ¾ PVC for sprinkler systems and you can use Schedule 40 for cold water supply in a house. Personally when I remodel my house I use ridged copper. I do know they are using ABS for Industrial use and in new Mobile Homes. I just called my plumbing contractor and he will call me later on today hopefully.
Anything you particular want me to ask him Ted.
Is this a water supply for your plants???
