The two holes you see in the water pump casting are called weep holes. The upper weep hole acts as an air vent. It allows air to evacuate the casting system and prevents the build up of humidity around the bearing. Also the vent allows atmospheric pressure into the pump and the seal remains seated. The lower weep hole exists to allow fluid to collect or drain out of the water pump to protect the bearing integrity. In a horizontal centrifugal pump there is little space between the bearing and the seal so fluid build-up could potentially threaten the bearing.
