What is the difference between a reverse rotation and a standard rotation water pump impeller?
Reverse rotation water pumps turn in the oposite direction of the crankshaft and are typically used with surpentine belts. The back (smooth) side of the belt is routed around the water pump pulley, thereby rotating it in the oposite direction of the crankshaft.Standard rotation water pumps turn in the same direction as the crankshaft and are typically used with V-Belts.Turning a water pump in the wrong direction will cause overheating.
After changing the water pump why wouldn't you be able to get the water to run through the engine?
Bad new water pump, thermostat installed upside down, hoses reversed, slipping water pump belt, system needs bleeding and has an air pocket. You must bleed the cooling system of all the air. Set the heater control to hot also when this is done to remove all the air in the system

How you can stop reverse rotation of cw pump?
Are you sure it's pumping in the wrong direction? It should be pulling water from the radiator through it's lower hose. Water will be returning to the radiator through the upper hose past the thermostat after it warms up. If your water is flowing the wrong direction and you have a mechanical pump ( one with a belt on it ) you will have to replace it. If you have a uni-belt setup (serpentine belt), it may be on incorrectly. If you have an electrical water pump ( probably aftermarket ) reverse the polarity on the power connection.
