17 17 PVC Pipe Installation Benefits PVC pipe and fitting price is 4 times cheaper than steel pipe’s. PVC Pipe weight is 6 times less than steel pipe’s. Use smaller pipe size because friction loss of PVC pipe is much less than steel pipe’s. Easy transportation, Easier and quicker installation, longevity
