Although some water leaks are so slow that they are not detectable, some known leaks are being ignored by some home owners. This is due to ignorance to the fact that small leaks that keeps on leaking would sum up into thousands of litres in a year. Imagine if all home owners had that same attitude? Each one of us should make our best efforts in the conservation of one the most precious commodity here on our planet – water. Not counting the added expense to your water bill. One such effort is to watch out for water leaks in our homes, no matter how small those leaks might be. Moreover, water leaks not only contribute to water wastage and cost, but also cause damage to some parts of the house’s structure. Damages to the house structural elements could cause the house to deteriorate faster, collapse, and injury.

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.

Water leaks usually happen in areas where the water-consuming appliance and plumbing fixtures are located. Here is our water leak detection guide. Among the most obvious areas to look for water leaks are

  • Bathroom & toilet area (check for leaks on the shower head, taps, and water heating system).
  • Kitchen (check for leaks on taps, dishwasher, water heating system).
  • Pool and spa.
  • Patio.
  • Water meter.
  • Laundry room (check for leaks on taps, clothes washer).
  • Garage / basement area (check the evaporator cooler, hot water system).
  • Lawn (check the grass, low water use garden, irrigation system).

Water leaks only worsen through time; it would be wise for you to deal with it as early as possible!
