We now offer the LeakSmart Snap-On Valve to protect your home from leaks for good. This valve snaps onto your existing system, no matter what type of valve you have. Then it shuts off your home’s water supply at the first sign of a problem.

What does LeakSmart provide?:

  • Total home water protection
  • Automatic five second shut-off
  • True 24/7 leak protection system
  • Advanced water flow analytics
  • Tracks daily, weekly, and monthly water usage

Not home? No problem. Download the LeakSmart app and connect it to your system. It can let you know if the system loses communication, like in the event of a power outage, and permits you to turn your water off from anywhere. It will also tell you if the system detected a leak and shut your water down.

If you have had a water leak in the past, you know how much damage they can do. Protect yourself today – you won’t be sorry!
