It could be it Depends who's doing it.
Sorry to be a pain but where is the sump where am I looking?
- I can see the water coming from the sump in your pictures. Get somebody else in, who is familiar with the boiler
Thanks I'm torn now do I get the guy out or call someone new . I can't keep chucking money at it lolThat black plastic thing on the bottom of the heat exchanger is the sump. The bit with the 2 screws in is the sump cover. If the previous engineer has been heavy handed tightens these 2 screws too tight it can crack it. But they have been known to just crack anyway (personally never seen one yet). It could also just be the gasket not sitting properly.
