The Benefits of DROP

The DROP App contains a robust amount of notifications to keep you informed. Everything from Leak Detection to Low Salt notifications, DROP has your back for all system events and items. They can be configured to push notifications, text messages, and emails.

Below is a list of all of the unique notifications available to you.

Automatically Respond to Detected Leaks

Worried about water leaks and damage to your home? With DROP Leak Detectors, you will never have to worry about that again! These sensitive devices can detect small traces of water where there should be none. You can configure these leak detectors to notify you of the issue as well as automatically shut off your water through your softener, filter or home protection valve to prevent further leaks and damage.

Long Flow Notification

Has someone left a sink running? This notification will inform you if water is running longer than expected based on your preferences.

Valve Error Notification

Has your softener or filter control valve malfunctioned? This notification will provide you with the correct information to help assess any valve issues in your water softener and/or water filter control valve.

Component Communication Lost Notification

DROP constantly communicates with its device endpoints. If your system is having trouble communicating with one of the devices, you will be notified and able to fix the problem.

Low/High Temperature

DROP Leak Detectors have the ability to notify you of temperature changes based on your preferred temperature ranges. If you lose heat in your home, your DROP Leak Detector will notify you.

Low Salt Notification*

Is your water softener running low on salt? With our patented DROP Salt Sensor, you will be notified if more salt is needed to continue providing softened water.

Slow Leak Test**

This unique test provides the status of your water system overnight by checking for small water leaks. By depressurizing your water pipes while you sleep, we can detect even the smallest leak in your system and help you identify where that is.

Filter Cartridge Notifications

Is your Whole House Cartridge Filter in need of a cartridge replacement? This notification will inform you to replace your cartridge to continue filtering and cleaning your home water.

Power Loss/Restored Notifications

Ever lose power to your important electronic devices and not know about it? This notification will notify you of this event. Never fear, as DROP uses battery backups on nearly all of its devices to continue operating without power.

Low Battery Notifications

DROP Leak Detectors and other DROP components operate on batteries using very low power consumption capable of lasting for years. If these batteries run low in power, you will know when to replace them.

Leaky Toilet Notification

Our technology is able to detect whether your toilet is leaking or not by pinpointing how much water is used during and after a flush.

Water Usage Surpassed Setpoint

Want to know when you have used a certain amount of water? This notification will let you know when you have crossed water use thresholds based on your preferences.
