While Most Homeowners Dread Damage from a Wild Storm or a Fire, Some of the Most Expensive and Frustrating Problems Can Be Caused by Water

Minor drips and leaks can be annoying, but they can also waste water and increase your water bill. Worse, a major leak can harm your home and your bank account. Thanks to technology, some of the costliest impacts can be avoided with the help of a leak detector that alerts you to the problem and, in some cases, shuts off the water to limit the size of the loss.

The Hidden Cost of Water Damage

Water damage is five times more likely than theft, according to the Insurance Information Institute. A small drip left undetected can cost thousands of dollars in damage. A report by Verisk Analytics found that one in 50 U.S. homeowners filed a water damage claim every year between 2013 and 2025, with the average claim reaching about $10,000 in 2025.

While major claims are dramatic, leak detectors can also address smaller-scale issues. The EPA’s WaterSense project estimates leaks in the average household waste nearly 10,000 gallons of water annually, with 10% of homes losing 90 gallons or more per day. Fixing common leaks can save homeowners roughly 10% on yearly water bills.

Devices With Leak Detection

Minor water leaks account for one trillion gallons of wasted water annually in the U.S.—enough to supply 11 million homes for a year. Leak detectors notify users when moisture sensors are triggered or abnormal water flow is detected. Advanced systems, such as the Flo by Moen Smart Water Security System, take a preventative approach by running daily tests to identify vulnerabilities like microleaks or pressure spikes, which could signal impending pipe bursts or mold growth.

Installation and Costs

Leak detectors are typically installed in high-risk areas:

• Under sinks
• Behind toilets
• Near water heaters
• In laundry rooms or basements
• Under refrigerators with ice makers

Individual sensors range from $50 to $100, while specialized detectors for drain lines or HVAC systems can cost $20 to $400. Whole-house systems like Flo by Moen start at $499 and require professional installation on the main water line. These systems monitor pressure, flow rate, and temperature, sending data to a smartphone app. If abnormalities are detected, the system can automatically shut off water to prevent catastrophic damage.

How Smart Leak Detectors Work

Smart detectors use sensors, Wi-Fi, and apps to:

• Alert homeowners via alarms, texts, or emails
• Shut off water manually or automatically
• Integrate with smart home hubs

Some insurance companies offer premium discounts for homes with leak detection systems, especially those featuring automatic shutoff valves. Check with your provider for eligibility.

Protection Beyond the Home

Advanced systems also monitor for freezing temperatures and high humidity, which can indicate pipe cracks or hidden leaks. For homeowners traveling, these devices provide remote monitoring and control, ensuring peace of mind even when away.
