Hi all

I have a newly fitted heat only boiler that is leaking at the point where the condense pipe enters the rubber fitting under the boiler. The siphon is not blocked and runs freely.

Any ideas?
 
It was only installed yesterday. My initial thought is a partial blockage in the condense pipe. Is that possible? Maybe water is backing up as the leek only happens when the heating kicks in on the initial fire up then stops. I had the thing running for over an hour yesterday with no problems whilst commissioning.
 
Solved!
As I suspected. Cut the condense pipe under the sink, outcomes the backed up water and what looks like grit, not my doing as always plug to stop that happening.
Drain clearing spring down the condense towards the kitchen sink waste and hey presto!

Hello I have a condensate pipe that appears to be leaking at the joint. How do I fix the leak? Would something like plumbers putty around the joint work or does it need to be some other compound? Can I simply pull the pipe and joint out and then put the compound round it Thanks
