This soaker line at Ohlde Dairy in Linn, Kan., is made out of schedule 80 PVC. The line made it through the summer last year in good shape, without any breaks. Based on that experience, Mike Brouk, dairy scientist at Kansas State University, says he is optimistic that the PVC can serve as an alternative to steel pipe. The PVC is half of the price of steel pipe, plus it’s easier to drill and thread for the installation of drip nozzles.
