Can I use Silicone to seal my intake trumpets?

Hi Daz,

Now I've got your attention, can you do me a favour and tell me what this is and if I can just blank it off? It leaks a drip at a time.




Cheers!

Purely a guess, but it looks like a pressure relief valve, especially if it's next to your boiler. If it is, highly inadvisable to blank it off.

It is indeed next to my boiler - have to find a replacement instead then I guess.

Most plumbing supplyers would sell them . Yes it is a safty releif valve . If your system has an open vent over the header tank do away with it ,, Dont plug it with an iron plug get a brass one . You will have to drain the heating system to do it ...
