Solution to my leaking water pump weep hole?

Water pumps are actually designed knowing you can get a smidgen of coolant past the seal. The cavity ahead of the weep hole is intended to be large enough such that the coolant dries up before it ever comes out of the weep hole. If you've got coolant coming out and even enough to go onto the floor, that seal is leaking way more than intended. Bad deal but a replacement looks like is in your future...
