How Do Water Leak Detectors Work?
Water leak detectors – also known as leak monitors – are a fantastic way to reduce your bills, ensure a functioning household, and prevent thousands of dollars of water damage. And all that without breaking the bank as these nifty gadgets are often very budget-friendly. But how do they work exactly? The main design feature of water leak detectors is the ability to monitor the flow of water through a pipeline and detect any irregular flows or leaks. The next step depends on the brand and the design: some detectors will notify you of the leak in a variety of ways, giving you a precious head start to react and prevent major damages; while others will automatically shut off the water flow and immediately contain the leak. The basic, affordable designs work on a simpler principle: they have placed at all key locations where leaks can occur, and when they come in contact with the water – they let you know. Such sensors can be placed beneath the sink, by the washing machine, or near a washbasin: that way you are first to know when the water is where it shouldn’t be.
And then there are the advanced designs that follow a modern set of features and can give you absolute control over your house water systems. Such detectors usually connect to the water meter or directly onto the water inlets and monitor the flow of water through the pipes. Depending on the design, they can give you all the necessary information on your smartphone: giving an important insight into your water usage data, and other important tidbits. Of course, when the flow of water becomes indicative of a leak, you are quickly notified and can react. In several designs, the detectors can shut off the water supply on their own – this is most common in washing machine leak detectors. Needless to say, this is the ideal solution that contains the leak before it can do irreparable damage to your household.
In the end, water leak detectors are a great gadget to have no matter which design you opt for: their ultimate result is all the same. Whether you want more control over the process or want a more affordable yet reliable alternative, you’ll still get the same advantage of knowing when a leak happens- and that alone is priceless.
