Thanks for the advice but it's actually leaking around the coupling

Yes, I can see that. I didn't mean remake the compression joint (which
you'll have to do anyway). I meant undo the flange fitting, clean up,
apply sealant, redo.

I had a similar problem where on mine the flow and return pipes in to the
cylinder were leaking .I had to undo the connection and got rid of the crud with
a wire brush then do it up again using tape and also some heat resistant
silicone I got from Screwfix .Hasn't failed yet and that was about 2 years ago .
