Hi guys, I moved my boiler to a new location but forgot to mark pipes return and flow, now I have to connect it back but I have no idea which is flow or return, I am not sure if it is any help but I refilled the system to find out from which pipe the water came first that is the only thing I know, hope you guys could help thanks in advance
