well pump safety device

They also protect your pump from burning up if the well goes dry.

Only if you happen to still be using water when the well pumps dry. If the pump is just refilling the tank when the well runs dry, the pressure will not drop and the low pressure cut off switch will not protect the pump. Something like a Cycle Sensor that reads amps instead of pressure will protect the pump from dry run even if you are not using water at the time. But it will not shut the pump down for a leak in the system.

There are variable frequency drives custom built for well pumps as "constant pressure". Iirc some will sense high flow and low pressure from a pipe break and shut down.

Cycle Stop Valves and Variable Frequency Drives both deliver constant pressure. The VFD does it by slowing the motor rpm, and the CSV does it by slowing the flow in the line. But either way the leak needs to be large enough for the pressure to drop. With a small leak neither the low pressure switch on a CSV system nor the computer program on a VFD system will shut the pump down.

I have a floor flange for a toilet piped into my basement slab. It is piped through the slab, directly into the septic. I installed this when I built my house. How can I use this as a safety to drain basement water in an emergency. I'm not planning on installing a toilet soon.

Your question was BAD LEAK *
The Sq D devices are just for that!

* like frozen pipe or a solder joint that lets go.

The water cop is expensive, of course money well spent to prevent a basement flood.
What I'm looking for would be a water sensor, connected to the pressure switch of the pump. When it detects water, it cuts off juice to the well pump. Seems real simple, can't find anything like that.

I think you could use the Water Cop for that. Just connect it to a relay that cuts power to the pressure switch instead of connecting it to an electric valve.

Looks like it would work, I'm leaning toward a DiversiTech WS-1 Wet Switch Flood Detector, 24volt transformer, and a relay wired up to the pump stair switch.
