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.

* Specific notification for DROP Water Softeners only.
** Specific notification for the DROP Home Protection Valve only.

    Drop products make it easy to manage your entire water treatment system. One of my favorites is the drop home protection valve. I have Honeywell Total Connect and we bridged it into this.

    In addition, they have recently integrated with Home Assistant and now Universal Devices EISY (pronounced EASY). I have other company sensors around the house and the EISY shuts off my water if those are triggered.

    Another feature is leak detection. I already had it tell me a toilet had a slow leak.

    Thank you DROP!!

    The DROP Home Protection Valve is the most fully featured smart valve that I’ve found on the market. The latest update to the HUB has enabled MQTT support for device information and local control. The protection valve pressure sensor has assisted with identifying PRV irregularities. I regularly use temperatures values, flow rate, and daily usage in automations. Despite further nuances, I highly recommend DROP products over current competitor products.

    Install was easy; however, a plumber replaced the home protect valve included plastic spring backflow valve with a brass one. The included plastic backflow had a high pitched whine when water was used at pressures above 55 PSI in my system.

    The valve motor is large. It may fit entirely in a 2×6 wall cavity, but I will need to fur my wall out a bit more to accommodate it. Pay attention to all dimensions so opening the box doesn’t lead to sizing surprises.

    The flow meter is not sensitive enough (or the software doesn’t show) to notice when my whole home humidifier is on. Pressure drops accordingly. This causes false negatives with the slow leak detection since flow isn’t detected, which returns the valve to service, but pressure continues to drop beyond the threshold.

    The slow leak action will try again later if water is in-use. This is generally great, though I wish I could set a specific time window to attempt retries. Some days, it will attempt a leak test almost all day as it constantly gets interrupted (working from home and weekends).

    I had my valve installed before my house inlet and my lawn irrigation. I did this to track accurate usage of water use and potential leaks in the yard. This comes with the caveat of the Home Protection mode scheduling. There are not programmable seasonal schedules, so I will need to adjust the protect mode settings with the change in seasons. This functionality is not controllable via home automation (at least not yet), and will probably not affect the majority of users. I don’t think I would buy a second at full cost just for irrigation.

    DROP support has been amazing so far. The app and web interface are functional. Monthly usage emails for trends are a nice touch. The app supports giving view access to others. My home insurance company does not support DROP yet, but DROP has the capability.

    Even with the minor usage nuances, I would not hesitate to recommend DROP products to others. I am eagerly awaiting a leak detection rope accessory for the leak detectors, and will continue to look for DROP products when needed.

    Solenoid controlled water shut off. It was able to shut off water supply when 8 gallons/min was exceeded.

    Excellent product! Design and fabrication quality are better than other designs I considered. Software integration is this products strong point. primary use is water pipe integrity and monitoring water pressure.

    Frost proof outdoor wall hydrant was covered by foam insulation “inside” the basement sill and wasn’t able to absorb heat. Unexpected freeze caused hydrant to fracture. The protection valve sent an alert and shut off the water preventing major damage and saving us thousands. Also, water pressure variations and alerts helped diagnose a failed expansion tank on the water heater.

    I have a customer that travels a lot, and liked the idea of remotely shutting her water off and her home being protected so I brought up the drop home protection valve, and instantly she wanted it! It works FLAWLESSLY.
