Yes, the Leak Defense System is adaptable to most residential and commercial applications. The Leak Defense System can be installed on pipe sizes up to 8” in diameter.

We suggest using the Control Panel to turn the water off and then back on monthly to ensure the valve is moving freely. We also suggest that an “Alarm Condition” be created occasionally to check the system's functionality. If you are using the Wi-Fi app, check to make sure you are receiving the notification that your system has alarmed via the app.

We recommend a Spring Check Valve is installed upstream of the Leak Defense System to stop backflow from occurring (which may lead to bounce). If you have a Spring Check Valve already in place, please call 1-866-410-1134, option 2 for technical support.

A complete installation of the Leak Defense System is comprised of three key elements. First, the plumbing must be completed; second, the wiring and programming of the system settings must be completed; and third, the installer must take time to explain the systems functionality to the owner. Obviously, all of this can vary from installation to installation. Two man crew installations seem to be most efficient. As you become accustomed to installing the Leak Defense System, the amount of time required for each installation will obviously decrease.

The majority of the tools and supplies needed to complete a Leak Defense System installation are items a plumbing/HVAC installer will typically stock in their service vehicle. You may view a complete list of Tools and Supplies on page 4 of the Installation Guide.

Yes. While the installation of the Leak Defense System itself does not involve wiring, some of the accessories require low-voltage wiring. This low-voltage wiring can easily be accomplished by following the steps in our Installation Manual. For additional questions or assistance, please contact 1-866-410-1134, option 2 for technical support.

Many Homeowners Insurance companies do offer premium discounts for policy holders who have leak detection devices installed in their homes. The discounts are determined by the Department of Insurance of each state. It is likely that your insurance carrier would offer one as well.

You can easily turn the water to your home off at the touch screen control panel, or from your Leak Defense System mobile app, by pressing "WATER" and "TURN WATER OFF". 

While in the HOME Scene, the Leak Defense System will start a warning cycle once the flow parameters are exceeded. It will close the valve for a moment, and you will feel the water flow drop and raise again as the valve is reopened. Without leaving the shower, you will have about 2 minutes to shut the faucet off yourself. Leave it off for about 30 seconds and the Leak Defense System will see that water flow has stopped and it will automatically reset itself so you may finish your shower. If water flow does not stop during this warning cycle or the system is in the AWAY Scene, it will fully alarm and shut the water off.

For panels purchased before mid-July 2020 or with blue background, press the time to the right of the applicable Scene name (HOME or AWAY), enter in the desired time (HH:MM), and press the upper right-hand box.

For panels purchased after mid-July 2020 or with black background, press the time in the lower left-hand corner while in the applicable Scene (HOME or AWAY), enter in the new number of minutes (i.e. for 1 hour, enter 60 minutes), and press the upper right-hand box.

For panels purchased before mid-July 2020 or with blue background, press the desired Scene name: Home, Away, or Standby.

For panels purchased after mid-July 2020 or with black background, press the Scene select button and choose your desired Scene: Home, Away, or Standby.

You can easily turn the water to your home off at the touch screen control panel, or from your Leak Defense System mobile app, by pressing "WATER" and "TURN WATER OFF".

1) Clear or silence the alarm (to disable the siren, press "SILENCE" or "CLEAR ALARM". Water will still be off). 2) Check for possible leaks (check faucets, toilets, and appliances). 3) Turn Water On (Keep an eye on the flow percentage after the valve is open). If your system is still showing flow, please call 1-866-410-1134, option 2 for technical support. 

Tap the "WATER" button and choose "WATER ON".

The first step in the process is to have an assessment completed at your home. A licensed plumber will fill out a one-page form with basic questions about the home and where various items are situated on the waterline. This will give us an idea of where the system will be installed and what items would need to be accommodated or bypassed (Like: determining cyclical water items, accommodating irrigation, filtration, pool fills, well equipment, etc). It will also give the plumber an idea of how the system will be installed, and what the labor proposal should include. For additional assistance, please call our office at 1-866-410-1134, option 1 for customer support.

We suggest the Control Panel be located inside the home near the most often used entrance/exit or near your security alarm panel. This allows for easy accessibility and interaction with the system during your daily routine. If you are connecting the Leak Defense System to a security system or using the app, the Control Panel may be installed in a mechanical room where it won't detract from the décor of the home.

The Leak Defense System will be installed on the main water line where it enters the home. A licensed plumber will install the system and they will determine the exact location during the pre-installation property assessment.

The Leak Defense System does not differentiate between regular water usage or water flow caused by a leak. When water begins flowing, the adjustable time parameter begins to count down. If water continues to flow without a break and it exceeds the user-set time limit, the system will alarm and shut the water off. The time parameters can be easily adjusted for both the HOME scene and the AWAY scene. 

The Leak Defense System can be integrated with most home monitoring systems using our All-Purpose Interface (API).

1) Take note of the current flow rate indicated on your control panel. 2) Press the "Water" button and turn the water off. 3) Press "MAIN" or "BACK" to see the home screen. 4) Has the flow rate dropped to 0%? If YES, you will want to investigate further to see if you can isolate the source. Consider checking for running faucets, toilets, showers, ice makers, and any outdoor hose bibs. If you still cannot find the source, please call 1-866-410-1134, option 2 for technical support. 

POLD's are great for any high-risk or high-value area, e.g. upstairs washing machine, water heater in the attic, refrigerator/icemaker, art gallery, or area with valuables that you don't want to take the chance of them getting wet, etc.

Once you have confirmed there are no active leaks, slide the battery cover open on the back of the alarming POLD and firmly press the internal reset button (models made before Jan. 2022). The POLD will stop "chirping" and you can then clear the alarm and restore water from the touch screen control panel. For troubleshooting assistance, please call 1-866-410-1134, option 2 for technical support.

If your system was purchased in 2018 or later, you can purchase POLD's directly from us and simply add them to your control panel. For details, please call 1-866-410-1134, option 1 for customer support. 

Since each home varies in levels of insulation, we recommend keeping the POLD within 100' of the control panel. This can easily be tested upon installation to make sure there is communication.

Yes. You will need an LDS-3-API (All-Purpose Interface) relay module. One of the technicians from your security company will need to complete the connection between the API to your home security system. For additional assistance, please contact 1-866-410-1134, option 2 for technical support. 

No, the Control Panel will need to be plugged into a non-switch non-GFI outlet and each sensor is powered by 2 AAA batteries.

 The POLD uses two AAA batteries. The average battery life is 2 to 3 years but may vary depending on conditions. When the battery life has dropped below a certain level, the control panel will display a low-battery alert and you will receive remote notifications if enabled through the Leak Defense System mobile app.

Up to 15 POLD zones can be handled on one Control Panel. Multiple POLD's can be handled in each zone.
