Uwe: not sure what your experience has been, but in a previous life looking after a Capital city's electricity infrastructure here in Oz, the observation from users that emergency equipment was faulty invariably came after the emergency event. Of course, the appropriate time for such findings should happen long before event - and that's the purpose of routine maintenance testing!Well, this is not good. Sump pump in the office basement isn't pumping:
No, as far as we were able to see, the pump never ran at all. And yes, it had power.It might have been the case that the pump capacity was insufficient for the size of the deluge - but this shouldn't cause the pump to fail.
He's gonna replace the pump.I hope said building owner was suitably contrite?
