It does sound like a venting issue. Try removing the vent cap on the roof and fill the tank from there, if the water soon backs up you found the problem.
I like the idea... Is there no sort of check valve in there though? In the bit I can find it is just a straight pipe to roof. So water in the vent should answer that question. Ear to the tank underneath should hear it hitting..
Worth a shot...
