Carbon build-up at gas valve

[TonyJMB]

What causes the build up of carbon deposits at the inlet side of the gas valve (i.e. upstream of the mesh filter)?

Is it a symptom of a problem somewhere or merely a regular service requirement? If the latter, how often should it need to be done?

TIA

Yes, also one of the disadvantages of some these forums is that one often gets wildly conflicting opinions from the 'Experts'
You still have to assess which is the most likely one to trust.
I hope you make more progress than I did.

I've just read you're 'sooty thermocouple' thread. Basically, you were advised to stop messing with it and get someone out. You may not have liked that advice, but it wasn't that hard to understand.

Its not soot it is something the shippers put into the gas network to help seal leaks and comes through the pipework and is caught in the filters of the gas valves

Pay attention namsag I never said it was soot. I was replying to digital des' whinging that he never got very good advice.

Thanks for the sooty build up link.

I am not sure that the deposits I have seen are like this, but it is difficult to tell from the picture.

Blue/black colour, almost the size of large grains of rice (can't think of any other way of describing them).
