Hi Bryn
I had the same with mine it seems to be a common fault,what I have done is sleeved it with a piece of plastic piping and jubilee clips and it works fine in fact when I had my last service he commented on what a good idea it was and saved a lot of stripping down to replace the whole pipe.
You won't get it leaking there again if you look at the rest of the pipe I think you will see the rest is fine.
Brilliant suggestion, much appreciated!! The breakers are all asking around £100 for a replacement so will definately try your idea
Cheers, Bryn
Just a quick upadate. The corroded section was chopped out replaced it with a flexible pipe/jubilee clips.
It's been on a week, no further leaks.
Thanks again to Norlec and Tigerfish
Bryn
