thanks steve
so why would they fit them then if not necessary?? just as an over precaution for if the vent or feed got blocked?

Never understood why they were fitted if you have a 22mm open vent, they usually drip after time and I have removed many of them and replaced with a iron plug. But then I've never understood why an auto bypass valve is fitted to a system with a 3 port spring return valve?
