And you were obviously correct but the difficulty was that it was only blocked occasionally and has to be running to block itself (if you know what i mean); which made checking with the flexible rod that i used a pointless exercise. Plus i didn't really know what i was looking for. Anyway thanks for all the help from everyone.
I need someone to open it up and fix it now. Not my bag.
