When we talk about home security, our first thoughts go to burglary or fire. Yet, the disaster that affects the most households each year is neither one nor the other.
The most common everyday disaster
According to data from the Home Safety Observatory, as cited by France Assureurs, more than a million water damage incidents are recorded in France every year, which is about 4,160 reports per day. Water damage is presented as the leading cause of everyday incidents for the French, ahead of fire and burglary.
The difference between a leak caught early and one that takes hold
A leak under a sink or near a water heater only becomes a major incident if it has time to spread: a few drops at regular intervals during an absence of several days are enough to soak a floor, a wall, or the dwelling below. The difference between a minor repair and water damage that requires insurance intervention often comes down to the time that elapses before someone notices it.
What the observatory says about prevention
The same press release indicates that half of the water damage incidents observed inside a home can be avoided by applying simple preventive rules. The text does not detail these rules one by one, and it would be inaccurate to claim that it specifically recommends a connected detector. What is established is that a significant portion of these incidents stem from causes that could have been spotted before reaching such a scale, which is precisely the role of a device that alerts you upon the first contact with water.
Where a detector makes the most sense
Under a sink, at the base of a water heater, behind a washing machine, or in the bottom of a basement: these are the spots where a slow leak can go unnoticed for several days due to a lack of regular traffic. A detector placed directly on the floor in these locations reacts as soon as its sensors touch water, before it spreads any further into the room.
What to check before installing
Battery operation requires regular checks of their levels; otherwise, the detector will not fulfill its role when it is needed. Smartphone notifications require a stable WiFi connection in the chosen location, which is not always guaranteed in a basement or a utility room far from the internet router. A leak detector also does not exempt you from normal plumbing maintenance: it alerts you when an incident occurs, it does not prevent it from happening.
Multiple sensitive points, multiple detectors
For a home that has several sensitive points—water heater, washing machine, dishwasher, basement—it is possible to install multiple detectors rather than just one: each one monitors a specific point, and the alert indicates where it is coming from.
The corresponding product
The WiFi connected water leak detector from SentinHome sits on the floor and sends a local audible alert as well as a smartphone notification at the first contact with water. Find our entire selection on our home security page.
