Is a water sensor better than a backup sump?
There is the secondary sump pump option in case the first one fails. Then there is the battery backup option which seems like it only works for a short period if the power goes out. I'm not sure either is worth it because in the rare instance of a failure or long power outage, my water sensor should go off and I can go down and manage the water myself.
Part of the reason I ask all this is I am also looking to get my radon mitigated because I am averaging about 100.
What do you think?
