I just finished putting together a circuit, testing it and creating a video for an automatic bilge pump. This circuit can also be used to trigger a warning light or noise/sound.
Easy to build and inexpensive. The video shows the pump working. Enjoy!

Pump (3-5V submersible) - I see the same on Amazon (2 for $7 US) the link below. Temu is even cheaper.
TIP120 Darlington available everywhere (~1$ US).
Tubing is 3/16 inch dia. (Tygon, aquarium, etc) .
Resistor 2K ohm I used a 2.2 K ohm (OK).
Breadboard - most anywhere electronics are sold.
Wires, small gauge. I used only black and red pairs to keep wires together.
Connectors - common small red battery type.
Plastic parts - If anyone has access to an FDM 3D printer, I can send you the STL files via email.
