Hi,
Finally got around to looking at a leak near the boiler that has been annoying us ever since moving in. I removed the offending component and, having googled, it appears to be a Spring Safety Valve.
Now, having tried to replace like with like but having no luck at the sheds, I have temporarily stuck a stop end in the place that the valve used to be. Having thought about it though, I don't see any reason not to leave it there, as the system is vented so I can't anticipate any need for a safetly valve.
Having pondered what to do I thought I would ask the kind chaps here to see if anyone can come up with any strong reasons why I should go to the lengths of getting a new one and fitting it.
Thanks in advance, Ric.
