I don't normally replace the olive unless I want to replace the nut as well (with a nice shiny new one) that you can't remove because of the olive.
To remove the old olive I use a junior hacksaw blade and cut through the olive as far as I dare, so the pipe is not damaged. Then using a suitable flat bladed screwdriver put in the slot and twist. The olive should then become free (as will the nut!).

So long as the fitting hasn't been over tightened I find you can usually get the old olive off by adjusting a large adjustable spanner to snuggly fit the pipe, and using it as a slide hammer on the nut of the fitting against the olive. But having got it off I wouldn't re-use it unless my back was to the wall (ie Sunday night everywhere closed and wife wants a shower!) and then I would aneal it (heat to red hot) before use.

IME if the fitting is done up properly and not distorted, there is no need to replace the olive.

On the issue of removing olives ( not required when reffiting existing compression joints..usually ) I noticed a plumber using an olive nibbler. Looked like a pair of pliers whith biting ends. Just cut through an olive in a second leaving the pipe intact.

I don't, often (almost allways) they are stuck to the pipe real well.
I just clean them up, and re-wrap with PTFE.

You probably don't even need the PTFE: I either use nothing but the olive or, if the joint is likely to be inaccessible, a bit of boss white. Seems to work pretty well!

Never had any problems with this method and no joints ever jumped apart!

I also use Andrew's slide hammer method. If the joint was made correctly in the first place and not over tightened, then the olive comes off fairly easily. If it does fit a new olive. If not then a few wraps of PTFE, or jointing compound.
If using jointing compound, for those who may not be aware, be sure it's fit for the purpose,especially if using compression joints on potable (drinking) water supplies. Boss White is not suitable for use on potable water.

If its the same fitting and pipe then clean up with wire wool then lightly smear with jointing compound. No problem.

Hi
OK you've convinced me, after all it'll save money reusing the olives. Now, I can understand cleaning them up with wire wool, though it seems a little fiddly for a 1 jar of olives, but what I dont understand is how you get the olives back after you've eaten them. Anyone?
