Hello all, Well I don't do sprinklers, evidently I just break them. A customer of mine pulled out one of his rainbird sprinkler heads that we broke, and claims he was unscrewing it and it just pulled off. The coupler was attached to a flexible ribbed dark grey 1/2 inch pipe. Do you guys know what adhesive to use to attach it back? I called rainbird, and after being on hold for 10 minutes the tech support guy came back and said they couldn't comment on what to use because they don't sell the pipe, just the head. He told me to go to Home Depot and ask them, to which I replied I'd have better luck going and asking a hobo underneath one of the highway bridges here in town. The homeowner tried PVC glue, and it shot up like Old Faithful on him. Thanks for any help!
