Thanks managed to top up my condensing boiler,,however a tip for other guys is to make sure the return valve is off is to take the hose off the cold feed and make sure there is no flow,, i had a small trickle so stuck a pan underneath and turned the valve till it stopped,,,, also if you over fill the system you can drain from here too ,, watch this valve as it does go both ways !!
