The danger with pipes bursts is that they can flood your house in seconds. Those accidents cause on average $5,000 in damage on average.

There is a simple way to avoid this and probably the idea with the return on the investment.

How does it work?

Install an automated shut off valve linked with leak sensors that would stop the water supply immediately at any sign of water.

  • Place leak sensors to all wet areas. This is generally under each sink and bathrooms/laundry rooms
  • Shut off valve should be installed on mains (recommended) or in each wet room
  • Plumbers support is recommended when installing mains water shut off valve

TIP: You can use the water shut off valve to switch on and off your mains remotely when leaving for a long time. Perfect for holiday homes or for peace of mind

What do you need? (And How Much It Costs)

DeviceOur RecommendationPrice

IR hub

A dedicated bridge
that emulates your
IR remote
$10 - $30

RF hub

RF bridge that emulates your Remote


  • Sonoff RF Bridge ($23.99) is our favourite RF bridge. The first thing you need to do is to flash it with Tasmota. This will allow you to connect to your bridge but also just control the bridge better.
$20 - $30

Shut off valve

A valve that will close and open water supply
  • leakSMART Water Leak Detection Kit ($365.72) is a more expensive option. It has all you need to set you up shut off valve. There are some negative comments on the hub but it works well in general.
  • Grohe 22503LN0 (from $14.00) is even more expensive. For the additional price, you have flow sensors capable to detect the pipe bursts without the sensors and better overall build quality. At the same, it has fewer options for integrating with your smart hub.
$99 - $400

Door/Window Sensor

Reports if a door or window is open or closed
  • Zigbee:  SmartThings Multipurpose Sensor ($19.81) is the best sensor by Samsung. Reliable, good battery life and looks amazing
