Filling loop on boiler?

are you sure you have filling loop valve turned off?
turn off mains and then remove loop to check which end water is coming from,if it's coming thro valve it needs to be replaced,don't have to drain system for this end just turn mains off and fit new valve try and get direct replacment then it should be easy.
