The one at the rear by the heat exchanger is leaking slowly. Tool station sell them for a couple of quid, but cautious about replacing one in the boiler after 20 years of use.
Do they unscrew easily and is the sealing compound adequate to seal the housing onto the pipe boss?
I have tried unscrewing so far to try to flush out debris, and that has helped. does that usually work, could try unscrewing more to flush more?
