I need to swap over my bypass valve and just wondered if the differential valve is the same thing?
Basically it sits between flow and return of the two manifolds in my bore system! It has been leaking and the pipes are extremely hot after the bypass valve meaning water is getting through, this in turn means my heated water is circulating straight back to the boiler and overheating the boiler!
I think this valve was blown due to expansion vessel having no air in it!
Expansion vessel is now sorted so I'm hoping replacing this valve will stop the water circulating back to boiler and enable it to travel down the notorious to the roads!
When looking for a valve, differential is coming up, seems to be a similar valve but just wanted to make sure they are the same thing!
Thanks
