PVC Repair - Pool Equipment

[gswhiteley]

I am replacing an in-line chlorinator for an outdoor pool system. It's on a 2" PVC line, and the old chlorinator I'm cutting out butts up against an elbow. Any ideas on how I can cut the 2" line up next to the elbow and replace the new chlorinator when I'll have an old pice of the 2" PVC pipe in the elbow?
