Most smart water leak sensors are typically easy to install and provide an early warning system that can save you a bundle in water damage repair costs, and some even work with other smart home devices to help minimize the damage. The Peril Protect ($23.99 per month for the Essentials Package we tested) is a subscription-based detection system that uses multiple sensors and a cellular hub to generate text and email alerts when water is detected. It also notifies a 24/7 call center that will contact you if you don’t respond to a generated alert, and will put you in touch with a local plumbing service if repairs are necessary. The sensors performed well in testing and notifications arrived quickly, but this is standalone system that lacks the third-party integrations and voice control that you get with the D-Link DCH-S161 Wi-Fi Water Sensor ($50 each, no subscription required).

Design and Features

We reviewed the Peril Protect Essentials Package, which includes four water sensors and a hub for $23.99 per month. The company also offers a Preferred Package for $27.99 per month that comes with seven sensors and a hub, and a Premier Package for $31.99 per month with 10 sensors and a hub. If you want to add more sensors to your package, you’ll have to pay an additional $2 per month for each additional sensor.

At 0.8 by 2.7 by 2.7 inches (HWD), the sensors are rather bulky compared to the tiny Orbit B-Hyve Smart Flood sensors (0.5 by 1.7 inches). They use proprietary wireless technology to communicate with the hub and are powered by a sealed non-removable battery rated to last up to five years. When the battery gives out, Peril Protect will send you a new sensor. There are four water sensor terminals on the bottom of each device, and one side of the sensor holds an LED indicator, an on/off button, and a test button. 

The hub is a white triangular device that measures 1.0 by 6.0 by 5.0 inches. It has a single adjustable antenna, a power switch, and a power jack around back. Inside are cellular and RF radios and a rechargeable battery that will supply power for up to 18 hours in the event of a power loss. An LED on the front of the hub glows red when you first power it up, then glows green to indicate a good cellular connection (the company doesn’t indicate what cellular network it uses).

The Peril Protect system doesn’t interact with any smart devices such as smart plugs, fans, and thermostats, nor does it work with Alexa, Google, or Siri voice commands. It also eschews Android and iOS mobile apps. Instead, it uses a PWA (Progressive Web App) and a web console to let you edit your profile settings including your name, email address, location, and account and monthly billing information. There’s also a Devices screen that displays the hub name and all of your sensors by name. To edit a sensor name, tap the pencil icon and select a sensor location (toilet, sink, laundry, main valve, etc.) from the pop-up list. The Alert History screen contains a list of all leak events by date and time, and tells you which sensor was triggered, while the Insurance Info screen is where you go to enter your insurance policy number and policy type in order to qualify for possible savings.

Here’s how the system works: When water is detected, the Peril Protect sensor LED will flash green four times and then will flash red while the sensor emits a beeping alarm. It sends the alert to the hub, which will also emit a loud beeping sound and its LED will flash green and red. Text and email alerts are automatically generated and sent to your phone and email inbox using the hub’s cellular radio, and a notification is sent to the call center. If after several minutes you do not respond to the alert, a live agent will call to inform you of the potential leak and to see if you need assistance. At this point you can have the agent set up a service call with a local contractor to make any necessary repairs. 

Installation and Performance

The Peril Protect sensors are pre-paired at the factory, making installation quick and easy. Simply place the hub in a central location, plug it in, and wait a few seconds for the LED to turn from red to green. Then place the sensors in those areas that you wish to monitor, such as under a washing machine or water heater, next to your main water valve, or anywhere else where leaks may occur. Flip the switch on for each sensor and you’re good to go.

The sensors were very responsive in testing. I received text and email alerts immediately when a sensor detected water, and the beep alarm from the hub was loud enough to hear from the other side of my house. At first I wasn’t receiving calls from the call center when a sensor was triggered, but it turns out my contact phone number was incorrect. A Peril Protect spokesperson quickly rectified the issue and I received calls whenever an alert went unanswered. The call center personnel were always friendly and professional.

Conclusions

The Peril Protect is a good choice for homeowners who want a cellular-based water leak detection system that will continue to report leaks even if your house loses power. It’s easy to install and performed well in testing, but it requires a monthly subscription and lacks the smart features that you get with the D-Link Wi-Fi Water Sensor DCH-S161, including Google voice control and support for IFTTT applets that allow it to interact with other smart devices. If you’re looking for a more powerful smart water leak system, the Flo By Moen Automatic Shutoff will detect systemwide leaks and shut off your water when the pressure is too high or when it senses abnormally high usage. It also works with Alexa and Google voice commands and IFTTT applets, but it’s expensive ($499.99) and requires professional installation.
