I have a potterton suprema 30 boiler and in the airing cupboard I have a stopcock which is on a small gauge pipe than the rest of the setup. It goes from output side of pump before actuator valve to the pipe coming out of the bottom of the tank. Is this some sort of bypass and should it be turned off or on? Sorry for my non technical explanation.
Also I have a Myson CP53 pump, what flow rate should this be set too, thanks in advance.
