Hi. I am installing a sprinkler system in the UK using sprinklers and parts I bout from sprinkler warehouse in Houston. I got everything except the pipe so now I am trying to find a substitute for 1inch nominal schedule 60 PVC pipe or an adapter. The fittings - blank PVC pipe connectors to glue onto the pipe- have an ID of 33.4mm or 1.32 inch. The nearest pipe I can find has an OD of 32mm or 32mm or 1.26 inch. This small difference means gluing will not work without an adaptor. Any ideas?
