The Smart Water Sensor catches water where it starts and pushes alerts into the Grand Alarms app so the right people can act fast, even after-hours.

Not Just Reports It
Notifications are great. Containment is better.
If you pair flood detection with a compatible water shutoff valve, Alarm.com rules can trigger automatic shutoff when water is detected.
Sensor Placement
Where Water Will Show Up First
The Smart Water Sensor shines when the leak source is tight, tucked away, or low, and you want the transmitter mounted higher.
Top business placements:
✔ Mechanical rooms near boilers, pumps, expansion tanks
✔ Water heater rooms and hot water tanks
✔ Under sinks (washrooms, staff kitchens, janitor closets)
✔ Commercial kitchens near dishwashers and ice machines
✔ Laundry and utility rooms (washers, mop sinks)
✔ Sump areas and low points (probe low, transmitter higher)
✔ Storage rooms near plumbing lines
✔ IT rooms that sit adjacent to plumbing runs (yes, it happens)

Sensor vs Tile:
Which One Do You Actually Need?
Smart Water Sensor
✔ Best when the transmitter needs to be mounted higher and protected
✔ Great for sump areas, mechanical rooms, and under-sink plumbing
Smart Water Tile
✔ Best for ultra-low clearance areas where a probe is awkward
✔ Great under appliances, behind equipment, and tight corners
Built for Set-It-and-Forget-It Installs

What Customers Like About Flood Detection

Ziad – Port Perry, Ontario
“Installed near the dishwasher and ice machine area. Caught a leak early and avoided damage to the flooring. That alone paid for it.”

SMART WATER SENSOR
Water Damage Is a Silent Budget Thief
Leaks do not announce themselves.
After-hours exposure time is where the costs explode.
Repairs are expensive, downtime is worse.
One leak can impact multiple suites, floors, or tenants.

How It Works
Sensor Event → Alert → Your Team Moves
When water is detected, the sensor reports to your panel, then Grand Alarms notifies the people you choose.
You can route alerts differently for each location, so the right staff get the right messages.
