No more overflow issues

Saved me from flooding my basement. The sensitivity is adjustable and the build quality feels durable for the price point.

Wire length insufficient

Functionality is good and the sensor detects water accurately. However, the probe wires were too short for my deep tank and I had to extend them.

Great automation solution

Installed this on my rainwater tank and it works flawlessly. The pump turns on and off exactly when needed without any manual intervention.

Reliable for pool top-up

Been running for 3 months now to keep my pool level stable. No false triggers and the relay clicks cleanly every time.

Works well, instructions vague

The module works perfectly for controlling my sump pump. I wish the wiring diagram was a bit clearer for beginners, but once set up it is solid.

5 FAQ

Q: Does it stop the pump automatically?

A: Yes, the module is designed to cut power to the pump when the high water level is detected and resume when the level drops.

Q: Can this handle 220V pumps directly?

A: No, this is a 12V control module. It controls a relay which can switch higher voltages, but the module itself requires 12V DC input.

Q: Are the probes food grade?

A: The probes are made of Stainless Steel 304 which is non-corrosive and safe for water storage, but we do not certify it for direct drinking water contact.

Q: What is the max cable extension?

A: You can extend the probe cables up to 10 meters without significant signal loss, provided you use proper insulated wire.

Q: Is the controller waterproof?

A: The controller box is IP65 rated, meaning it is protected against water jets, but it should not be fully submerged underwater.
