Leak Detector Operations

DROP Leak Detector Overview

DROP Leak Detector

The DROP leak detector is designed to detect water leaks and temperature conditions that can cause water leaks. It is powered by 2 AA batteries, which under normal circumstances will last for many years of operation. A leak detector monitors its leak probe input for water. If water should come in contact with the probes, the leak detector will immediately report the leak to the DROP system. The DROP system will immediately send a notification of the leak (if connected to DROP web services) and will shut the water off at the DROP valve. Shutting the water off can optionally be turned off if your leak detector is not monitoring a system component that is affected by normal source water (such as a condensate pump). The leak detector that sensed the leak will then chirp every 16 seconds and the yellow leak light will flash every 2 seconds.

DROP Leak Detector Placement

In order to reliably detect a water leak, it is very important that the location where the leak detector is placed is well thought out. First, when considering where to place leak detectors think about the locations in your home that use water. Next, think about what locations are most vulnerable to problems. For example; appliances that use water and run unattended, pipes that are more susceptible to freezing, or toilets that are known to overflow or leak.

Also, think about the consequences of water in those areas. Maybe monitoring a water heater in an unfinished basement isn’t as important as monitoring a bathroom on the second floor of a home. Prioritize the locations that need protected the most. Also, keep in mind that if more leak detectors are needed, you can add up to 32 leak detectors to your DROP system at any time. Finally when you place the leak detector we recommend that you test where water will tend to accumulate by purposely spilling a small amount of water in that area. Once you observe where water naturally moves to, you should accordingly place your leak detector in that location. Don’t forget that you can name your leak detectors according to their location in the app, on the SYSTEM > STATUS page. This will help you locate a problem quickly if a leak does occur. Leak detectors can obviously be placed in the location that you want to detect leaks.

However, there are available accessories for leak detectors to allow more flexibility in their placement and use. A wall mount bracket and a leak detection extension cable are available and can be used to securely mount your leak detector and permanently mount the leak probes exactly where they need to be located.

DROP Hub Connectivity

DROP Leak Detector Operations

Once you have placed the leak detector in the location that you would like, press the “Check/Silence” button. After a few moments, the green okay check mark should light up indicating that it was able to communicate with the Hub. If the red no network light turns on instead, then the leak detector is too far from a powered DROP component on the DROP device network. Any DROP device that is powered with a wall plug power supply can repeat the messages to the Hub.

The options for helping a leak detector connect to the Hub are:

  1. Move the DROP Hub to a more central location in your home.
  2. Move another DROP powered component closer to the leak detector you are trying to connect to.
  3. Add a DROP network extender to your network in-between the Hub and the leak detector that you are trying to connect to the system.

DROP Leak Detector Settings

DROP Leak Detector Settings

Leak detectors are ready to use as soon as they are connected as a device to your DROP system. If you have not yet connected your Leak Detectors to the system, please see the section “Adding devices to the DROP system”. Once connected, by default they will shut off the water when a leak is detected and set a notification.

By going to the Devices menu on the left side of your app and then choosing a particular leak detector, you can decide for each leak detector if it should shut off the water, or just send a notification. Leak detectors also monitor temperature. High and low-temperature set points can be set for each leak detector. If the temperature should surpass the set point a notification will be set.

Reporting Operation

DROP Leak Detector Settings

Leak detectors report to the Hub every 10 minutes under normal circumstances. If the leak detector does not succeed in checking in, it will try again once a minute until it succeeds. When the leak detector has missed a check in, it will flash its network light until it is able to connect to the Hub again. If it has not succeeded in checking in with the Hub after one hour, the Hub will send a notification that the leak detector has lost connection. If this happens regularly, you may need to help improve the DROP network as indicated at the end of the section Leak Detector Placement.

If a leak occurs, temperature changes significantly, or temperature surpasses a set point, the leak detector will report to the Hub immediately.

Battery Operation

Leak detectors use 2 AA batteries to operate. The detectors typically sleep most of the time and therefore use very little power. Under normal operating conditions, they will operate for several years on the same set of batteries. When they do get low the low battery light on the leak detector will begin to flash and the leak detector will chirp once a minute (but only outside "Quiet Time" hours). A low battery notification will also be sent by the DROP system.

Leak Detector Factory Reset

It is recommended that before performing a factory reset, that you remove the leak detector as a device on any DROP system that it might be attached to. This can be done while using a local connection in the App and going to SYSTEM > ADVANCED page. On that page, you will see “Manage Device Components” Find the leak detector in that list and press the “Remove” button associated with that unit. Once it is removed then perform the factory reset.


To reset a leak detector and cause it to forget any DROP network that it has been connected to, press and hold the button while inserting the batteries. Continue to hold the button for 15 seconds. During this time all the lights will be on solid. Once the button has been held for 15 seconds, the lights will begin flashing once per second. At this point the leak detector is armed for reset, release the button and then press it again to cause the leak detector to be reset.
