New to Prime Day? We’ve got everything you need to get started . Sales information is accurate at time of publication, but prices and availability are subject to change.
If you own a home, you’ve probably learned to fear water—I certainly have. Not only has my home flooded several times due to natural disasters, but I’ve also had to deal with unseen leaks from old plumbing. And these unseen leaks can cause a lot of damage if they’re not caught right away: They ruin the structure of your home and invite mold and insects to grow.
That’s why I learned a long time ago that installing leak sensors (aka water alarms) throughout my home is a necessary step if I want to sleep peacefully at night. If you haven’t already, now’s the time, because this awesome three-pack of leak sensors from Treatlife is a whopping 75% off for Prime Day. That means you can get twelve sensors for the price of three, and protect your entire home from water leaks — from toilets, dishwashers, water heaters, kitchen appliances, crawlspace pipes, walls or basements, washing machines, and under sinks. Plus, these sensors can warn you of roof leaks before they become noticeable, saving you from serious damage.
The alarms connect to your Wi-Fi network and are controlled via an app on your phone (they’re also compatible with voice assistants like Alexa and Google Home). Simply insert the batteries and discreetly place them near potential leaks. When they come into contact with water, they’ll sound a loud — and let me tell you, these alarms are LOUD — alarm and send a notification to your phone at the same time. This is important because it allows you to react to a leak while you’re away from home. The app will also alert you when the batteries need replacing, so you don’t forget.
These Treatlife WiFi Water Leak Detectors are 75% off and are a great investment in the safety and security of your property. I have them all over the place and for the price, they are the perfect way to keep your home leak-proof.
