Water leak detection can either be done by periodically checking the areas and components of the house’s plumbing system or by installing a commercially available water leak detection device.
There are mainly two types of water leak detection system
Passive Leak Detection Systems. These are usually stand-alone battery-operated devices that produce alarm sound when its moisture sensor becomes wet, these alarms enable the home owner to locate exactly where the water leaks are and do the necessary repairs. Since these are battery-dependent devices, its battery should be checked regularly.
Active Leak Detection Systems. These also sound an alarm when it detect water leaks, and will automatically stop the water flow. It may use a moisture sensor or a flow sensor in monitoring any water leaks. There are two types of Active Leak Detection System
Whole House Systems – monitor leaks in the whole house and shut off the main water supply to the house should leaks be detected. A Whole House System is composed of several moisture sensors which send signal to control valve via radio signal or wiring connections.
Individual Appliance Systems – monitor leaks from a single appliance and automatically shut off water supply should leaks be detected.
Every house is unique and has a special situation to determine what type of water leak system is applicable. Some simple systems may be installed by the home owner, but complex systems should be done by qualified plumber.
If you don’t have a water leak detection system device installed in your house, you can always check your house periodically for any water leaks.
