Large Diameter Pipe Adapter

I am trying to extend my current system due to a remodel. The issue is the existing pipe is 2"id and 2,24"od. It is a grey thinwall PVC pipe. where can I get a section of pipe and three couplers? Or is there an adapter to go from the old larger to the new smaller pipe? Any help is greatly appreciated, Thank you


The best way to handle this is using the Schedule 40 to CVAC Pipe Adapter. It may be a little loose on the wide side but using plenty of glue should do the trick. Once the adapter is on your wide pipe you can use regular central vacuum pipe to continue the run. You can use another adapter to go back to the wider pipe.
