Default Coolant leak HELP!

Replaced my water pump and i got a leak at the inlet hose. The upper radiator hose that goes into the water pump leaks right at the end. I replaced the house and put a good "constant torque" clamp that really clamped it down. It did not cut into the hose and the hose is seated nicely. not sure what else could be the problem. its a slow leak but enough where i have to add a little coolant every couple days. any ideas?

I would get a pressure tester and pressurize the system with the car cold and look and feel for where the leak is exactly coming from.

Hmmm, I don't know, maybe its leaking and the water runs where the top of the hose goes. Other than that, I don't know why it's not sealing.
