Why worry about water escape, when a simple leak detector can prevent the problem? Our compact, easy-to-install, battery-powered leak detector provides peace of mind - and is perfect for domestic appliances such as the latest filtered/hot water taps, dishwashers and washing machines. PEACE OF MIND. The leak detector features an integrated automatic shut-off feature - so if the worse happens and a leak is detected - the leak detector will automatically shut off your water system. The leak detector will also alert you to a leak by emitting a beeping noise and displaying a blue, flashing light. NO POWER SUPPLY REQUIRED. The leak detector uses a 9V battery. And don't worry, there's no need to worry about forgetting to replace the battery as, just like a smoke alarm, the detector will shut-off your water supply when battery power is low, too. It'll also alert you by beeping and displaying a red, flashing light. RETROFIT WITH EASE. It's really easy to retrofit the leak detector - so it's just as suitable for older homes as new ones. NO INSTALLER NEEDED. There's no reason why a competent handy person wouldn't be able to fit the leak detector. However, if you are uncertain about any aspect of the installation, we would always suggest you engage the services of a qualified professional installer. Please note the leak detector comes with full installation instructions and all fixtures/fittings., Manufacturer: BWF
