More Heating system help?
Seeing that there are a number of very knowledgable members on here, can anyone tell me what this is and where i might get another one?
It is my oil heating system, and is in the oil supply line, with a return from the boiler.
As you might see it has a crack in the plastic dome, and is very slowly leaking, not much at the moment, but I do want to replace it sooner rather than later.
I am sure I can do it myself, just need a new part, which is the same as the existing part.
