Air block on hot tap problem

[maximus]

Hello all, i have just replaced my toilet and basin/taps in my bathroom upstairs, I have run the system and all other hot feed taps are fine in the house but I cant get a drop out the one ive changed, ive checked all valves and had the mixer tap off and apart. One thing to mention is I previously had the same fault on the water feed in question when I first bought my house, I had a plumber in who re piped a section of it and he said the previous owner had tapped off a vent? He held his finger over the tap and it started to back feed in to the tank? Anyhow when he'd finished all was right, for months, untill now. Any help would be appreciated.

Thanks for your reply, sorted it now, tried the finger over tap trick but to no avail. Managed to suck it through by mouth in the end, got rather light headed but all is now as it should be
