Water leaks can cause severe damage to your home and cost you a lot of money in repairs. The longer the water sits, the worse the damage will be. That’s why it’s so important to have a reliable way to detect water leaks as soon as they happen. See which water leak detectors we’ve chosen as our top picks for a variety of needs you may have in your home.

Article Overview

Why Do I Need A Water Leak Detector?

It makes sense to have a water leak detector in your home for several reasons. When you can detect a leak instantly, it will reduce the cost of your water bill, limit the amount of damage to your property and minimize the amount of work it will take to clean up the mess when a leak occurs.

It also makes sense to understand what homeowners insurance covers when it comes to water damage so you can best protect your home.

Consider These 8 Things Before Purchasing

Here are some factors and specific features you’ll want to consider when choosing a home water leak detector.

Google Home speaker
Some water leak detectors work with smart speakers like Google Home.
  1. Areas to monitor: Decide where you’ll need to place the water leak sensor or if you need something specific for a basement or to monitor water consumption.
  2. Battery or plug-in: Battery-powered wireless water leak detectors make it easy to monitor places that are far from outlets, while plug-ins don’t require you to change a battery for them to function.
  3. Built-in alarm: A detector with a built-in alarm will sound a siren so that you immediately pinpoint where the leak is coming from.
  4. Freeze sensor: Some detectors can alert you when they sense freezing conditions to help avoid pipes bursting.
  5. Alerts: Some water detectors can also alert you through a base station or an app.
  6. Smart-home integration: If you already have a smart home product, like Amazon Alexa or Google Home, you should consider a product that works with it.
  7. Installation: Will you install this yourself or need to hire a professional?
  8. Added costs: Be aware that there are often added costs if your detection system requires a base station or a professional monitoring plan.

Best Smart Home Water Leak Detector: StreamLabs

StreamLabs Smart Home Water Monitor Leak DetectorView on Amazon 

The StreamLabs Smart Home Water Monitor detects leaks and freezing conditions throughout your entire home with just one device. You can remotely monitor your home with 24/7 real-time alerts sent directly to your app, and this device is compatible with Amazon Alexa.

Not only will the device detect leaks and freezing, but it also monitors everyday water usage, which helps you track changes and keep water bills down.

DIY installation is quick and easy and doesn’t require any pipe cutting or professional installation. All you have to do is attach one monitor to your pipes. This plug-in monitor needs to be within 5 feet of an outlet, or you’ll need an extension cord. Also, it doesn’t have an audible alarm.



  • Tracks water consumption
  • Freeze and leak alerts
  • User-friendly app for Android and iOS
  • Smartphone alerts
  • 24/7 real-time monitoring
  • Built-in WiFi
  • Works with Amazon Alexa

Best WiFi Water Leak Detector: Honeywell Lyric

Honeywell Lyric Leak DetectorView on Amazon

The Honeywell Lyric WiFi Water Leak and Freeze Detector detects leaks, senses temperatures from 30°F to 150°F and sends alerts for humidity, which can help prevent mold formation.

You receive alerts through the smartphone app, text and email. There is also an audible alarm. WiFi is built-in, and this leak detector doesn’t require a base station. It also includes a 4-foot water sensing cable that expands the coverage of your water detection area. You can purchase additional cables to expand it up to 500 feet.

Even though you can place it in a variety of spots around your home, like the basement or garage, you must place it near potential leaks for it to be effective. They do not include batteries, and it gets complicated if you want to use multiple units around your home because the directions for installing multiple detectors are vague at best.



  • Alerts for water, humidity and temperature
  • User-friendly app for Android and iOS
  • Smartphone, text and email alerts
  • Built-in WiFi
  • Battery-powered
  • Built-in alarm
  • Flexible placement
  • Easy installation
  • Complicated setup for multiple units
  • Must place near a potential leak
  • Batteries not included


Best Water Leak Detector With Professional Monitoring: SimpliSafe

Our pick for best water leak detector with professional monitoring is the SimpliSafe Water Sensor. This leak detector stands out because it’s part of a home security system. You can add this to your existing SimpliSafe system, or you may want to consider adding a home security system to protect your home from perils beyond just water leaks.

When the water sensor detects water, an audible alarm sounds, and you will get alerts on your smartphone through the app, text and email. In addition to the water sensor, SimpliSafe offers a variety of sensors, and you can connect up to 100 sensors to the base of your security system.

Personal Experience

We have this home security system in our second home, and the most valuable part of it so far has proved to be the water leak and freeze sensors. Since the house is in a colder climate, we are commonly concerned about frozen pipes and knowing these are monitored so we can quickly respond if there is an issue. These sensors help us rest assured. – Michelle S., homeowner

Because this leak detector is part of a home security system, equipment costs are higher. And there’s a monthly fee if you go with professional monitoring. You can place the sensor in multiple locations around your home, but the sensor needs to be near a potential leak. You also don’t get alerts when the battery is low.



  • Smartphone, text and email alerts
  • User-friendly app for Android and iOS
  • Battery-powered
  • Built-in alarm
  • Flexible placement
  • Works with SimpliSafe home security system
  • Easy installation
  • Monthly fee if you choose professional monitoring
  • Equipment costs are higher
  • No low-battery alert
  • Must place near a potential leak


You can see all the options for pricing and packages on SimpliSafe’s website. You’ll have the option of several pre-built packages, as well as building your system a la carte.

Monitoring Options

You can purchase a SimpliSafe Security System without a monitoring plan, but you will only be alerted by local alarms. Adding the monitoring allows you to get the most out of this system.

Best Budget Water Leak Detector: Govee

Govee Water Leak DetectorView on Amazon

What’s great about the Govee Water Alarm is that you can use these budget-friendly alarms independently without a base station. Govee also sells a remote monitoring kit if you decide you want that option. But even the cost of the kit, which comes with one alarm, and adding a couple of extra Govee alarms is still less expensive than other products we review here.

One unique feature of the Govee water alarm is that there are 2 sets of water probes on the back and one on the front to detect leaks on the floor and drips that come from above. You will also enjoy the ultra-loud built-in alarm that you can hear from anywhere in your home. And the low-battery alert lets you know when to change the batteries.

Just keep in mind that you must purchase the remote monitoring kit, which has a WiFi gateway, if you want smartphone alerts for water leaks. Just like with Honeywell and Simplisafe, the location of the sensor is flexible, but you also must place it near a potential leak to be effective.



  • Can use with or without remote monitoring
  • User-friendly app for Android and iOS
  • Battery-powered
  • Built-in alarm
  • Flexible placement
  • Easy installation
  • No alerts unless you purchase the kit
  • Must place near potential leak
  • Requires WiFi gateway for remote monitoring
