Water dripping from flue casing - Worcester Bosch Greenstar CDi

[Lottie]

Hi

On our Worcester Bosch Greenstar CDi boiler the flue emerges from the top, through a 90 degree bend and exits through the wall (at a v slight incline) about two feet away to one side. One section of the flue inside the house has 3 small pop rivets in it and water is dripping from the rivet at the bottom. I have collected 175ml from it in last 20 hours. This happens whether its raining or not. I could probably stop the rivet dripping but the water will then presumably run back into the boiler. Should there be water in the outer ring of the flue which I understood was the air intake? Should I worry about this and get it looked at or just put a blob of silicone or something on the rivet to stop the leak? The boiler was fitted in 2008 and this problem has only just started.

edit: There are only 2 rivets (I assumed one round the back but there isn't). Here is a picture (if I've managed to get it up...):

Lottie, if you have gone through the replies you will see that this situation is serious enough for experienced proffesionals to tell you not to use the boiler until it has been checked by a GSR engineer

Thank you for that advice. May I ask you please to explain precisely what a GSR engineer is? Does that differ from anyone who advertises themselves as qualified to install and service gas boilers.

Re other points raised in the thread:

The flue is not horizontal. It slopes up from the boiler to the exit through the wall as I think I said originally.

Its a bit dark out there but this is what is on the outside (if this attempt to post pictures works). I removed the protection cage to photograph it.

Its got the right terminal atleast. GSR is Gas Safe Registered. I strongly advise you to turn the boiler off until that flue has been checked out, its not been joined correctly and more than likely is leaking fumes.

sorry Lottie
GSR gas safe registered engineer

when the engineer does arrive try and get a photo of where the 2 pipes join if possible, then post on this thread

Might be worth a quick look under the rubber gasket round the flue to see if its been sealed correctly.

A said it doesnt look like a WB flue? the pipe on the left looks like a different coulor, the pipe on the left looks like WB and the pipe on the right doesnt, have they just jammed in a extension from another boiler? dont reley on your co alarm, new flues for this boiler are cheap enough, still available and easy enough to fit.
