There is a sump pump in the basement, in a basin, with a power cord going into it, and a pipe going out of it. How can I test the various kinds of functionality of this setup?
I can put a bucket of water into the sump and see if the pump starts - I suppose that tests the float switch, etc. How low should the water level in the sump be before it turns off?
But how do I actually test that it is doing its job of keeping water out of where it's "not supposed to be"?
