Yes — as long as the water passes through your main water line, Droplet can detect it.
Droplet doesn’t rely on spot sensors. Instead, it uses ultrasonic flow sensor to measure all water activity in your home, even if the leak is:
Hidden under the floor
Behind a wall
Buried in a slab
Running quietly (like a refilling toilet or dripping faucet)
💡 If water flows through your pipe, Droplet will see it — no matter where it ends up leaking. But Droplet cannot tell you where the leak is - only that there is a leak.
