Undetected water leaks rank among the costliest and most disruptive problems a homeowner may encounter. From burst pipes to leaky appliances, even a small amount of water can cause thousands of euros in damage. That’s why a water leak detector is one of the smartest investments you can make to protect your home and belongings.
In this guide, we'll explain how water leak detectors work, where to place them, and why they should be a key part of your home alarm system.
A water leak detector, also known as a water sensor, is a small electronic device designed to detect the presence of water in areas where it shouldn't be. These detectors are usually placed near appliances, pipes, or low points in your home where leaks are likely to occur.
When moisture or water is detected, the sensor triggers an alert. With smart systems like PhoneWatch’s Water Leak Detector, this alert is instantly sent to your phone and to a 24/7 monitoring centre, helping you act fast and prevent serious damage.
Most water leak detectors work by sensing conductivity between two metal contacts. When water bridges the contacts, it completes an electrical circuit and triggers an alarm.
PhoneWatch’s detector also includes smart capabilities that integrate with your overall alarm system. This means that if water is detected, you're notified immediately, allowing you to take swift action whether you're at home or away.
The sooner you detect a leak, the sooner you can act. Sensors catch even small drips before they become major issues.
Water damage repair costs can escalate quickly. A small investment in leak detection can save you from massive repair bills, insurance claims, and long-term damage.
Leaks often happen in places where valuables or electronics are stored, such as attics, basements, or near washing machines. A sensor gives you the chance to move items before they’re damaged.
PhoneWatch’s water leak detector connects to your monitored alarm system, providing around-the-clock protection and immediate alerts via your mobile app.
To get the most out of your water leak detector, placement is key. We recommend installing sensors in the following areas:
Unlike basic standalone sensors, PhoneWatch’s water leak detector is fully integrated with your home alarm system. That means:
Many DIY water detectors offer local alerts only. While these may beep if water is detected, they’re not helpful if you’re away from home. With PhoneWatch, any leak detection triggers a monitored alert so you can act quickly—or have someone respond on your behalf.
Professional installation also ensures optimal placement and sensor performance.
While most people think of home security as preventing break-ins, true home protection includes safeguarding your home from fire, flooding, and other emergencies. A water leak detector is a simple but powerful way to round out your system.
PhoneWatch’s water sensors come as part of our complete home alarm packages, offering multi-layered protection with expert installation and 24/7 monitoring.
Ideal spots include under sinks, near water heaters, behind washing machines, and in basements or crawl spaces where leaks are most likely to occur.
With smart systems like PhoneWatch, you’ll receive instant alerts on your phone and the monitoring centre will be notified for rapid response.
Professional installation is recommended to ensure proper placement and integration with your home security system, though some wireless models may offer simpler setups.
