Best Smart Water Leak Detectors for Apartments (No Drilling & Easy Setup – 2025)

Why Every Apartment Renter Needs a Smart Water Leak Detector

Water damage is one of the most expensive and disruptive problems renters face — and it can happen fast. A small leak under the sink, behind the toilet, or near the washing machine can cause hundreds (or thousands) of dollars in damage, and renters are often responsible for notifying the landlord before a small leak turns into a disaster.

That’s where smart water leak detectors come in. These small, wireless devices detect moisture immediately, send real-time alerts to your phone, and help you catch leaks before they cause serious damage. Best of all — the ones we’ve picked for 2025 are:

✔️ Drill-free and renter-friendly
✔️ Controlled by apps for instant notifications
✔️ Affordable and easy to install

Here are the 5 best smart water leak detectors for apartments in 2025.
