Best For Septic Tank: Flotec Float shut off Switch

Buy on Amazon

It is a great automatic switch for a water pump without a switch. It includes a metal clamp (which you press the cord into, in lieu of a zip-tie), which requires a pump with a screw-in spot on its top. The switch cable is attached to the wall of the sump pit with a bracket. The switch requires 3.5" of play to function properly, but it doesn't need the full 7" from bottom to top to trigger. The extra long cord works out very well. The switch will open ( when it is angled downward far enough and the pump will turn off. The float is at approximately a 45 to 50 degree angle 'up' before it turns on the pump.

• A good design of float switch
• A good value for your pumping needs
• Can adjust to the water level you desire

Brody has been making great switch for years, thanks to a combination of clever design and appropriate materials. This pump controller will work effectively on a 12v solar array to power a Dankoff Slow pump. It allows electrical equipment to start and stop automatically (usually pumps, but also electric control valves, alarms, etc) with high reliability. It can be used with a sump pump to pump water that has risen to a certain level or can be used with a pump to fill up a storage tank when the water has fallen to a certain level. The lower switch is a safety to keep from burning up the pressure pump.

The other side of the relay will have the 2 110V leads going to your pump. They also have short actuation lengths, which means you have reliable switching no matter how much slack you give the switch. It is well built and made of quality materials.
