SmartLeak™ Automatic Water Leak Detector
Water damage is the #1 home insurance claim in America. Now there's a smarter way to stop it before it starts.
The SmartLeak™ Automatic Water Leak Detector silently monitors your home 24/7 — under sinks, behind toilets, near water heaters, and anywhere water shouldn't be. The instant it detects moisture, a piercing 100dB alarm sounds and an instant alert hits your phone.
Protect What Matters Most
<Every year, water damage costs the average homeowner $11,000. It starts small — a drip behind the washing machine, a slow seep under the kitchen sink. By the time you find it, the damage is done.
SmartLeak™ catches it first. In under 15 seconds. Before it becomes a claim.
How It Works
- 💧 Place it — Set the sensor on any flat surface near water sources. No tools, no wiring.

- 📱 Get alerted — The moment moisture is detected, an 85dB alarm sounds and a push notification hits your phone instantly.
- ✅ Act fast — Stop the leak before it spreads. Protect your floors, walls, and wallet.

Marcus T.
Verified PurchaseCaught a leak before it became a disaster
Set it up under my kitchen sink in minutes. Two weeks later it went off at 2am - found a slow drip from a cracked fitting. Saved me from a flooded cabinet and probably thousands in damage. This thing pays for itself instantly.
Jenna R.
Verified PurchaseSuper easy setup, totally worth it
I was skeptical at first but literally took 60 seconds to place. The alarm is loud - you WILL hear it. I bought three and put them under every sink and near the water heater. Peace of mind for the whole house.

Verified PurchaseLandlord approved, tenant loves it
I am a property manager and put these in 4 units. Clean design, no drilling, no setup headaches. Tenants appreciate that I care about protecting their belongings. Already prevented one water incident in a bathroom.

Verified PurchaseBest money I have spent on this house
After coming home to a flooded laundry room two years ago, I swore I would never let it happen again. SmartLeak sits right behind my washing machine now. Knowing it will alert me gives me so much relief. Sleek design too.
David P.
Verified PurchaseCompact, accurate, and fast
Tested it with a few drops of water and the alarm triggered in under 2 seconds. I have tried cheaper sensors before that failed - this one feels built to last. Battery life seems solid too. Highly recommend for anyone with older pipes.

Verified PurchaseGift it to every homeowner you know
Bought one for myself, then immediately ordered 4 more as housewarming gifts. Everyone who received one messaged me later saying how much they love it. One of those products you did not know you needed until you have it.
