the pump is unreliable (IMHO junk); Sensors are cheap, but serviceable

the pump does not work, "floats with oil" (see short video), makes unpleasant noises and after 10-20 minutes turns off the circuit breaker (it seems that it does not have one internal protection) . Oil also flows from it (photo). The sensors seem cheap but seem to work well.

Pros
