Old flushpipe to new toilet

[adamtw36]

I have replaced my downstairs loo, new basin, tap, toilet and tiles, and I'm very proud of it all, however I have fallen at the last hurdle.

When connecting the pan, the flushpipe leaks. The problem seems to be that the old concealed cistern has a flushpipe which is 38mm OD whereas new flushpipes and my new swanky toilet seem to need a 40mm OD flush pipe.

I've tried two different flush cones, one rubber (fits well in the loo) and one PVC (just keeps popping out no matter how far in I manage to push it.)

I've also tried plumbers mait but it STILL leaks when I flush.

Is there any way of connecting the 38 to the 40mm? I'm happy to use solvent, as I have some. I need to know if there's any tricks of the trade before I call a plumber out.

Thanks all.

If your pan is suitable for an external flush pipe connector I find they work better, not all pans have a suitable connection though.

Such as http://www.ebay.co.uk/itm/Toilet-Fl...682?pt=LH_DefaultDomain_3&hash=item19f6a2dfe2

Clean around where the connector sits with meths first. The pvc ones I find are not worth bothering with.

Heat from a heatgun or Very Gently from a blowlamp on the 40mm to form a socket by pushing in the 38mm let cool remove and solvent weld

Can you solvent weld a flush pipe? Wrong material surely. Not being argumentative - serious question.

If the flush pipe is not absolutely square as it goes into the pan, it will tend to leak.
