Installing safety measures, such as security systems and smoke alarms, is the baseline for protecting a home. And while leak detection systems aren’t commonplace in most homes, they definitely should be. According to the Insurance Information Institute, about one in 60 insured homes has a property damage claim caused by water damage or freezing.
“Water leak detection systems can be pretty affordable, especially when put up against the damage to your home if you have faulty plumbing, a burst pipe, or a leaky toilet,” says Adam Bakonis, Director, Product Management. “These systems can identify water problems early and help homeowners reduce out-of-pocket costs and claims that can cause their insurance premiums to rise.”
What Is a Water Leak Detection System?
A leak detection system monitors your water pipes or other high-risk areas for leaks to prevent or lessen water damage in your home. There are three main types of smart leak detection systems: point-of-use sensors, whole-home water-flow monitors, and automatic shutoff devices.
How Does a Leak Detection System Work?
Water leak detection systems vary by brand and type, and their components and capabilities differ. Depending on the system, sensors may detect moisture in a specific location or monitor water usage for unusual patterns that could signal a leak.
When a system detects water or unusual activity, it may sound an alarm or send an alert to your phone. Some devices connect through a central hub, while others communicate directly through Wi-Fi. Devices with temperature sensors may also identify conditions associated with frozen-pipe risk. Automatic shutoff systems can go a step further by closing a valve when they detect a potential leak.
Where Should You Install Water Leak Detectors?
Whole-home water-flow monitors are typically installed at or near your water meter so they can monitor usage across your property. Automatic shutoff devices are installed directly on the main water-supply line where it enters your house. If you have a water filtration system, follow the device manufacturer’s placement instructions or consult a qualified installer.
Point-of-use detectors should be placed in high-risk areas where problems are more likely to start. Common locations include under kitchen and bathroom sinks, near toilets and water heaters, behind washing machines, around dishwashers, and in attics, basements, or crawl spaces where pipes are exposed or water can seep in during wet weather. These small sensors provide an early warning before a minor issue turns into a major repair.
Benefits of Installing a Leak Detection System
Leak detection systems offer many benefits, including:
- Prevent costly water damage: Early alerts can help you respond before a leak spreads. Automatic shutoff devices can also stop the water supply to help prevent major structural damage to floors, walls, and foundations.
- Catch hidden leaks early: Not all leaks are visible. Small drips behind walls, under floors, or in rarely used areas can go unnoticed for weeks or months.
- Conserve water: Fixing leaks promptly helps reduce unnecessary water waste, whether it’s a dripping faucet or a malfunctioning irrigation system. Even small leaks can add up over time, so early alerts help you use water more efficiently.
- Protect your home environment: Moisture from undetected leaks can lead to mold growth and poor indoor air quality. By addressing leaks quickly, you can help maintain a healthier living space and avoid long-term damage to your home and belongings.
Can a Leak Detection System Lower Your Homeowners Insurance?
Installing a leak detection system may help lower your homeowners insurance premium by reducing the risk of water damage claims. Mercury currently offers eligible homeowners a discount of up to 4.2% for qualifying devices such as whole-home water-flow monitors like Flume or shutoff devices that can be installed by Beagle Services.
To see if you qualify for a specific savings opportunity, check with your insurer or Mercury agent. They can help you find available discounts and any requirements your system needs to meet.
If you want to protect your home from catastrophe, installing a water leak detection system is a great place to start. Certain systems can be big investments, but they’re worth it to prevent or mitigate water damage and expensive repairs.

Types of Water Leak Detection Systems
Not all water leak detection systems are the same. Here are the main differences among point-of-use sensors, whole-home water-flow monitors, and automatic shutoff systems.
Step 1: Point-of-Use Water Leak Sensors
Point-of-use leak detectors are the equivalent of smoke detectors for water leaks. Typically, you install them under a sink, near a toilet, or near appliances that could leak, like a fridge or washing machine. When these detectors sense water, they sound a loud alarm or send an app notification.
Point-of-use sensors are generally affordable and easy to install, but they only detect water in the locations where they are placed. They typically don’t shut off the water automatically.
Step 2: Whole-Home Water-Flow Monitors
Whole-home water-flow monitors track usage patterns across your property to spot unusual activity, such as continuous flow or sudden spikes that may signal a leak. They can help identify hidden or slow leaks and provide detailed water-usage information.
These systems send alerts to your phone but typically don’t shut off the water automatically, so you’ll need to respond to the notification.
Step 3: Automatic Shutoff Systems
Automatic water shutoff systems monitor water flow and can automatically close a valve if they detect a potential leak, helping prevent extensive damage. Many also send alerts to your phone and allow you to control the valve remotely.
These systems provide both leak detection and mitigation, but they tend to cost more and often require professional installation.
How to Choose a Leak Detection System for Your Home
Here are some considerations when choosing the right water leak detection system:
Step 1: Determine How Much of Your Home You Want to Protect
Whole-home water-flow monitors track water usage across your property, while point-of-use sensors focus on high-risk areas like under sinks, behind appliances, and near water heaters. Automatic shutoff devices provide broader protection by stopping the water supply when a potential leak is detected.
Step 2: Look for Features That Match Your Needs
You might want real-time alerts, smartphone notifications, and the option for automatic water shutoff if a major leak is detected. Installation requirements also matter. Some systems are professionally installed at the plumbing entry point, while others are simple plug-and-place sensors you can install yourself.
Step 3: Consider How the System Tracks and Reports Water Usage
Detailed monitoring can help you spot unusual patterns early and better understand your household consumption.
FAQs
Can leak detectors find leaks behind walls?
Some leak detection systems can identify hidden leaks behind walls by monitoring changes in water flow or pressure that don’t match normal usage patterns. While they may not “see” the exact location of a leak, they can alert you to abnormal activity so you can investigate before the damage becomes visible.
Are water leak detectors worth it?
Yes, they can catch small issues before they turn into expensive repairs or widespread water damage. Early alerts and automatic shutoff features can significantly reduce the risk of structural damage, mold growth, and costly insurance claims.
How much does a water leak detection system cost?
The cost of a leak detection system can vary depending on whether you choose a simple point-of-use sensor, a whole-home water-flow monitor, or an automatic shutoff device. Basic standalone sensors are often available for less than $100, while whole-home systems typically cost several hundred dollars before installation. The total cost will differ depending on the system, your home’s plumbing, and the complexity of installation.
Shutoff devices installed directly on the water line are typically the most expensive option, but they also offer more features and the ability to shut off the water automatically. Flume is a whole-home water monitoring solution that homeowners can install themselves. Mercury customers can purchase it for $99 upfront, plus $49 per year for continued service. The average premium savings with Flume is around $75, although actual savings vary. For some customers, the discount may cover the device cost within one to two years.
