Back to wall toilet too close to cistern?

[SpecialK]

I have a fluidmaster concealed cistern mounted right behind the panel that the roca back to wall pan is mounted to. I can't get the flush pipe to stop leaking. It is probably due to the pan being too close to the cistern? This has been installed for a good 5 years but sometimes starts leaking. I have already replaced the cone and given it all a good clean. Appears to leak from where the flush pipe enters the cone rather than the pan part.

Is there a way round this? Could I make up my own pipe that has less of a swept bend? I see there are some flexible ones but not sure how good these would be?

Thanks..

It's definitely a leak not condensation?

Oh yes it is piddling out every time it flushes

Should say the pipe is about 40mm both ends. Wondering if I can just make something up. The pan seems too close and the pipe is still on the bend bit entering the pan.

I wonder if this would work? "Ideal Standard Flushpipe Pack SV90567"

We had dripping under toilet from condensation forming on cistern.
I filled the inside with foam and it works although around January we still get a bit.
You can buy insulated cisterns or get a blender fitted so both hot and cold water fills cistern.

The pipe you refer to.
Is it this one? Here

You can cut to size.

That is the pipe I currently have - The problem is the bend sweep is too long so it is still thinner when entering the pan cone. It appears the ideal standard one is a straight 40 degrees. I might get a 40mm compression fitting to repair it temp and then get the ideal standard one

You could wrap PTFE tape around pipe to increase its width .

Get some self-amalgamating tape.
Stretch as you wrap around pipe so it amalgamates. Will thicken pipe diameter.
That will do the job as cone will seal

There is an aviation standard fixit tape that acts as a joining/amalgamating tape for aircraft parts, they literally stick it on the wing, but it is very expensive

If it's 1.5" then you can just make you're own flush pipe using a swept bend.
