Ultra-compact wireless water leak detector engineered to sit unnoticed in the places leaks actually start — under sinks, behind washing machines, beneath water heaters, in HVAC drip pans. LeaksProtect’s 14mm-thin profile fits where standard leak detectors won’t, and once placed, it works for years without maintenance. The detector senses water through two corrosion-resistant contact pads on its base: the moment both pads bridge with liquid, an alarm fires to the Ajax app and the hub triggers the system response — including automatic water shutoff if the property has an Ajax-controlled WaterStop valve installed on the main line. It pairs with the Ajax Hub 2 over the encrypted Jeweller radio protocol at distances up to 1,300m line-of-sight, runs up to 5 years on two AAA batteries, and includes tamper detection that alerts you if the unit is moved or removed. IP67 rated against full water submersion (so it keeps signaling while the flood is around it), operates from 0°C to +40°C. Ideal for kitchens, bathrooms, laundry rooms, basements, server rooms, and any spot where a slow drip or sudden burst can go unnoticed for hours.
