Dilema!!

[ruck'n'reefer]

I would like to remove a pvc reducer fitting from an existing cemented pumbing setup (actually a skimmer). Has anyone tried, or does anyone know if this can be done?

If so, any thoughts on how to do this. It is a 2"-1 1/2" reducer.

The main reason for this is that I have an unused 2" ball valve I would like to use and not have to buy a 1 1/2 valve.

Thanx
