How does it work?

The Leak Controller and the AquaGate sends a pulse every second through the two stainless steel probes on the bottom of the sensor and measures the resistance of the probes. In the event of a leak, the resistance across the probes drops, and the Leak Controller detects this and shuts off the water supply and sounds an alarm.

How do I test the Leak Controller and the AquaGate products?

To test your Leak Controller or AquaGate locate the sensor(s). Once you have located the sensor(s), there are two ways to test the product:

1) You can insert a coin into the slots located on the top of the sensor and wait for the
     valve to close.

2) You can wet the bottom of the sensor probes with your finger, a sponge, towel etc.

If everything is working correctly, the Leak Controller or AquaGate should beep 4 times, flash the LED, and close the valve. If it is not working correctly, change the batteries and retest. If the sensor test continues to fail, check the sensor connections to make sure they are connected to the probes and circuit board

How long do the batteries last? 

We have designed this product such that the theoretical battery life is 4 years.   The controller will consume more power during an alarm, and thus we recommend changing the batteries every 2 years.   Should you forget about the unit and the battery power reaches 85 % of capacity, the unit will alarm as if it has a leak.  Check for a leak, if the sensor is dry and there is no leak, it is time to change the batteries.  We have purposely allowed for adequate remaining power so the alarm will continue for months due to a low battery condition.

If the controller is beeping?

If theunit is beeping there are 3 possible causes: You have either had a leak, the batteries are low, or it has not been tested for two years. If you have had a leak, dry the sensor, fix the leak, and hold the button above the LED light down until the Light stays lit and you hear a beep. If you do not have a leak, and the Leak Controller has been in service for close to two years, hold the button above the LED down until the Light comes on and the Leak Controller beeps. If the leak Controller has been in service for more than two years and a leak is not present, change the batteries and return the valve to the green position.

Will the sensor detect a small leak? And how do I ensure against false alarms?

Each application is different and you should experiment with sensor placement to determine the best position.  This usually only takes a few minutes.  If you are unsure or you have a larger area to protect, we recommend using multiple sensors in series connected to one Leak Controller.  There is no limit to the number of sensors that can be attached to one Leak Controller.

If you wish to detect small leaks or there is an uneven surface, we recommend using the absorbent towel provided with the Leak Controller under the sensor. In our tests, the sensor easily detects just a few drops of water on the paper towel. If you are concerned about false alarms, use the sensor without the paper towel.

How do I ensure the sensor remains flat in a crowded under sink environment?

First, make certain the sensor wires are straightened to remove kinks from the shipping process. If sensor stability is still a concern, or there is concern for the sensor movement by the user, the sensor can be fastened to thesurface a clip that has double-sided tape on the bottom that you can slip the sensor wire through.  The clips can be found at most home improvement or electronics stores.  The fastening device should not be metal or interfere with the metal strips on the sensor.  Ensure that the sensor lies flat and is not raised off the surface once installation is complete.
