There is a method to check to see if your water pump is functioning. Take the pressure cap off. Remove enough coolant as to where you can see the top thermostat and the coolant has receded into the hose........Now start your car and stand straight up over the stat.........In a couple of mins you should see the stat open and the coolant being pushed through....If you hit the throttle gently you should see the coolant move faster into the hose....If you have no movement then its your water pump. But remember the coolant will rise, you should be able to tell the difference between rise and flow.....You could do this or remove the stat before you start the car instead of waiting for it to open.........
