Hi guys i have another question for you
I have what apears to be some type of bypass valve fitted staight after my pump that feeds back to the return to the boiler . It has a knob on the end and can be adjusted .
please can you tell me what this does and what ideal position it should be in or if it even needs to be there i have heard it could be using up more gas by having it
Cheers
Darren
