Water pumps fail for three main reasons (although there are other mitigating circumstances): use of the wrong coolant, failing to purge and replenish coolant that has been in the system too long, or simply wear and tear over years of use.
Whatever the reason, the best results can be achieved by renewing as many parts of the assembly as you can afford. Check also the radiator, hoses and ancillary parts - new parts are always beater than reusing the old items!
