Hello,

my pilot light no longer goes on (but it does spark) after the nice man at British Gas replaced the gas meter. After he left I managed to get the pilot on, and this was OK for a few weeks. Now it's gone off again.


I've checked the threads on this site, and on the troubleshooting flowchart on the back of the front plate of the boiler and would like to check the following:

- whether the thermocouple needs to be replaced. How do I check this?
- whether the pilot injector is blocked

I've taken a picture of the three pipes which are reponsible for the pilot. Could somebody be so kind as to identify which pipe is which?

thx.
