to prove its the water pump, remove the t-stat and run it with top radiator hose removed. water pump should gush water out the top hose. you can do this with engine cold. stick garden hose in the radiator to keep it full of water. as said, its rare for the wp impeller to rot away.
just a by the way, on the silly radiator drain, turn it 90* then pull out to drain. turn it another 90* and pull out to remove it.
