I have now registered - but previous thread is closed therefore, as I cannot reply, I'm starting a new thread...
Rckape, thank you for your prompt response, very helpful.
Plumben, also thank you.
Your responses make sense to me, however….
I have contacted 2 other heating installers to request a written report.
But Oh dear!
I have only had a brief conversation on the phone with both:
One knew immediately the green was flux. But then tells me that I need the whole heating system flushed as the flux will also be on the inside of the pipes and will continue to cause corrosion to pipes and radiators.
The other didn’t mention flux. He said it could be a bad batch of pipes. They will come and check the quality of the pipes.
I don’t think the quality of pipes in the issue.
However now I am concerned about corrosion on the inside of pipes and radiators.
I am not sure with this conflicting information.
The system was flushed after the installation. Will that have flushed out all the internal flux? Or is there a possibility that the radiators and pipes could corrode internally.
If there is, then should I request the installers to flush the system again?
In addition:
Some of the green cannot be accessed – pipes are right up against the wall, down the wall through the floor and down behind the boiler.
If the green is not cleaned off will it continue to corrode the pipes?
I’m still trying to work this out with the installers.
Initial post under previous thread:
Pipes are showing a lot of corrosion, 18mths after installing a new heating system and water pipes, in airing cupboard. There is corrosion around most of the joins of the pipes. Also spots and patches of corrosion on pipes. There is also corrosion on the gas pipe to the boiler. The corrosion has been cleaned off as it is on the outside of the pipe.
The cold water pipe to the shower pump has already had 3 pinhole leaks – it seems the corrosion was on the outside of the pipe – but I’m not sure. The pipe has been replaced.
I have read about excessive flux causing corrosion where the pipes have been soldered. Could this have caused the corrosion around the joins? However I don’t understand what the other spots and patches of corrosion are.
Would any one be able to offer any more information about how the corrosion could have occurred.
So far the current remedy of the installer is to clean the pipes.
However:
In my view this is not a permanent solution
Will the corrosion come back?
Will more corrosion occur in the future?
If the corrosion is not cleaned off I am assuming the pipe will corrode through to cause a leak?
Would there be corrosion on the inside of the pipes?
What is the solution? Should ALL the pipes which are showing corrosion be changed?
