A water pump is a shaft through a sealed bearing with a propeller on one side to move water around with and a pulley on the other side to take power from a belt. The seal can fail. This will create a water leak, usually slow or unnoticeable. Water on the bearing eventually corrodes the balls or rollers. This causes them first to squeak, then break down to the point where they can't hold the shaft straight any more or create so much friction that the belt slips. If it's not making noise, a properly tensioned belt doesn't slip, and it isn't leaking, don't worry about it. If you take all the tension off the belt, turn the waterpump pulley by hand, and don't feel something scraping or wobbling, your problem is elsewhere.

Well, a couple of things to watch for....and it could fail without ANY warning..
1, Is it NOISY? The noise usually means a bearing failure.
2, is it leaking? many water pumps will leak when they get ready to fail.

when water pumps fail, 2 things will happen
1. it will actually start leaking water though internal seals
2. the car will begin heating up
a free computer diagnostic may, maybe, will tell you if you have a bad pump, im not sure if it will but it might
free comp diagnostics are given at autozone

could be making squeeling noise or starting to leak around the weep hole at the bottom of it or your car could be heating up some.

it will leak,the bearing will make a racket and sometimes the propeller will break and make your car heat up.
