An overflow or a leak from an aquarium or it's equipment can cause a huge mess if not caught right away. The Watchdog is a stand alone leak detection alarm that will give a very loud audible alarm in the event water comes in contact with its sensor pads. It is extremely sensitive and we have found they even work with RODI water. The Watchdog monitor is small enough to slip between sumps and stands, or the wired sensor can be placed in even tighter locations. A single 9V battery (not included) will keep the Watchdog running for up to 24 months, standing by to alert you of the smallest drop of water that comes in contact with its sensor. The minimal investment in a Watchdog Leak Detector can save hundreds if not thousands in damages.


Placing the Watchdog in your stand, next to your RODI system, or any place where a leak could cause a catastrophe can help safeguard your home from water damage. The Watchdog Water on Floor Sensor will report a super loud audible tone to alert you in the event of a leak. The unit comes with a 60" lead to mount the extremely sensitive conductivity sensor securely wherever you may need it.

Pro Tip: By placing a paper towel under the sensors can help wick water towards the sensor for faster alerts, however the paper towel should be replaced every now and then for best performance.
