@chad Thanks to excessive paranoia about water damage, I've got a primary pump, a backup pump, and a water level monitor (submersible pressure transducer feeding data to Home Assistant) with various alerts.I've done nothing to deal with a rapidly filling sump during a power failure though.

@chad @javensbukan I’m hoping to make that one, but I have a work program that afternoon a bit earlier, so it is a bit up in the air.
