Dumb Plumbing Question

[Victorp]

Is it possible to change the pvc size for instance the pipe is 1/2" but the pump's output is 1" do I use a compressor or adapter or something like that? Another question I have is how do I get rid of a glued pvc pipe or unglue it? \
And can anyone recommend an external pump with 1" inlet and 1/2" outlet?
Thank you

You can get a pvc reducer or adapter from Home depot or Lowes very cheap.
To "unglue" a couple of pvc that are glued together, you can sometime twist and pull them apart. If that does not work, cut them off, pvc is very easy to cut, any saw will do the job.
