Try tightening all the clips and having a good feel round all the pipes before condeming the pump. I would put money on it being a pipe.

Quite often the water pump housing will have a small hole drilled in the bottom. The idea is that if the bearings in the water pump break then water comes out the hole to warn you of the problem.
Do you have any noises from the water pump?
To check the pump try removing the fan belt and checking the water pump pully for movement and try turning it to check for smoothness.
Good luck.
