What's this on our external Firebird 2.2 oil fired boiler system? May be just a general component but it drips occasionally and I suspect when it isn't, air is being sucked in.

Pressure switch needs replacing
If you decide to do it yourself be very carefully brazed on connection very easy to snap/distort/cause to leak.

If I recall, I dont think the new boilers have these. If so, remove and plug it and make the circuit in the junction box.
Certainly the Grant combi's got rid of pressure switch couple of years ago .We take take them out as part of service now awful things and very easy to snap off!
Can't comment on Firebird's never fit them.

That's probably what I'm thinking about, but the principle would be the same. I'd remove it. Low pressure will present itself in other ways and will not suddenly render a system unoperable at the most inconvenient time.
How does it seal into the connection if I go down that route or what size plug and if doing that can I just make the circuit using the wiring from it?
Be slightly careful.
That connection uses a stainless clip which needs to be pulled out first.
Then the switch might rotate ! It is just pushed in and has one or two "O" rings as seals. It has a groove higher up into which the clip locates.
If you could get that far then you could clean up the male part and try to replace the "O" ring. Easiest to use a box of many different sizes to select one.
If you cannot or do not want to do that than you will have to engineer a bodge. I would machine a new plug with an "O" ring and a groove to fit the clip.
Other possibilities would be to find or make a brass plug and when dry to solder it in place.
With standard bits you would need to cut the horizontal tube and fit a new piece with soldered or compression fittings.
But there are two nutted parts on the vertical section. If you can get these apart a 1/2" male blanking plug will probably fit sealed with PTFE tape..

Wanted to take top of cabinet off for better access. Apart from the self-tappers presumably this bolt needs to be undone, seems to be just turning.
Ah it's OK, had enough jiggle space to get the sensor out. Will get some O-rings tomorrow and see if that sorts it
