If the water pump bearings are worn to the point of allowing a tight belt to start it leaking, it's probably in need of replacement. Stop leak can/will gum up the entire cooling system eventually. It might be worse than the leak. If you used the stop leak, and then decide to replace the pump, make sure you flush the cooling system really well before refilling and returning it to service.
