Leaking Plastic Compression Joint

I think I've cocked up! I have installed a shower pump however the outlet valve of the pump is leaking. It connects to a copper pipe via a plastic nut and olive and I think I have overtightened this causing the valve to distort. I have bought a new nut and olive and tried fitting a new copper pipe but it leaks constantly. I have tried PFTE tape but this doesnt seem to do the job. Any ideas other than a new pump.

I have to assume this is taking place in the back corner of an airing cupboard and the pipe route is torterous. Try using plastic with a little give to allow you to get the fitting square on. First remove pump from tight corner and redress the thread with a brass compression nut with great care.
All the shower pumps that I've seen have flexible connectors from the pump outlets and inlets, typically with push-fit connections to copper or plastic pipe. Which shower pump is this?
sorry I was answering as though this was a dish washer, didn't read it properly. The Saniflow shower pump has flexible connectoir that fits solvent weld overflow pipe, you can buy a rubber bung which fits inside a 40mm push fit t which accepts the overflow pipe. Put that t on your washing machine waste before the trap..
