This is the “low water” alarm- the control box is detecting that the pump is using less power than normal ( pumping air ).

If your system is definitely pumping water, then it’s possible your irrigation pipes network isn’t putting enough pressure on the pump. You can turn the low water alarm off using the settings for that watering zone on the control unit dashboard.

Note that if you use a soaker or seep hose, with the WaterMate Pro pump, the pump will turn off when the pressure reaches 35psi, and turn on again when the pressure drops. This will cause the pump to cycle on and off, which will trigger the low water alarm. With this setup, turn the low water alarm off on the control panel.

If there is any other blockage to cause the pro pump to hit the high-pressure cutoff, you may get the alarm too.

Hi, I keep getting the 2 tone low water alarm whatever I do. I've tried recalibrating the pump back pressure as per the instructions, and nothing changes. Its pumping and the low water alarm is turned off and system is fed from a full waterbutt immediately adjacent, so theres no pipe or distance issues. Dashboard states back pressure is 1000/2000. Any ideas? Running the 4 season watermate mini.
