WAPU defective……

Hi, after which the cause of my water loss was found, I would be interested to know how long the WaPu is taking part, I already get a new one delivered (manufacturer’s warranty), but I can hear such an unpleasant grind in the engine room, which gets louder every day. Can the WaPu take a few more kilometers, or rather not drive any more, I mean not a world trip, but you what is absolutely necessary.
