“I have worked with, rebuilt, and repaired these units and they are usually quite good and work well for a long time. I got one that was bad out of the box. It failed to open the second valve when it was tested. The people at Pex took very good care of me by sending a return label and a new unit that goes in tomorrow.”
“Used these units for my irrigation system and they are performing flawlessly. The size and fit were as described and the installation was simple. I would recommend these units for any irrigation project requiring reduced pressure backflow preventors.”
