Should I buy an automatic water shut off valve?
There are many reasons why purchasing a smart water valve is a good decision
Prevent Costly Repairs
Smart water valve controllers and water leak detectors work together to detect leaks, burst pipes or earthquakes and automatically shut off the water system to prevent further damage and costly repairs.

By using smart water management mobile apps you’ll be able to set water consumption goals. It’ll ensure that you do not need additional utility costs.
Automatic Water Shut Off Valve Features to Consider
Device and Installation Costs
It can cost between $300 to $600 for a smart valve based on features required and if professional installation is needed.
Alert or Action
Next on the list is what you want from your smart water system. Do you want it to simply alert you to the problem or do you want it to stop the problem from developing further by automatically cutting water supply?
The sensors and monitors will provide you with those smart alerts, by email or app. However to stop the problem from developing you will need an automatic water shut off valve.
DIY or Plumber Install
If you would like to avoid the expense of hiring a plumber, then a motorized bulldog valve is the best option as it can be DIY installed. Otherwise you will need a professional plumber to make some changes to your mains supply line to install the device.
Micro Leaks
Some devices are more sensitive than others. It's worth reviewing the granularity of leak detection as some devices can identify leaks as low as one drop per minute.
Integrating your Smart Water Leak Detector
Most of the devices listed above connect to Amazon Alexa at a minimum.
However, to avoid even more smart home apps, you can choose devices that integrate with your smart home hub/gateway (via Z-wave or Zigbee) or are IFTTT compatible.
Power outlet available
Automatic water shut off valves typically require a nearby outlet power. Some devices also come with backup batteries in case of a power outage.
Common Questions relating to Water Shut Off Valves
A water leak shut off valve can automatically detect water either by monitoring the flow in the supply pipe or by sensing water on the outer floor. When an irregular flow or moisture is detected, the valve instantly shut-off the water flow via an internal ball valve. This can prevent catastrophic water damage.
Water Leak Shut Off Valves can be installed by integrating a device into the main supply line or by motorizing an existing bulldog valve. The devices are then typically powered via a nearby power outlet and connected to your smartphone via the local Wifi or Smart Hub network.
There may be several problems that result in water leaks. Some of the most common causes of household water leaks are broken seals, clogged lines, corrosion, excessive water pressure, loose water connectors, and extreme temperature fluctuations.
For single-family use, you just need one. Place it next to your main supply valve as it can shut off the main supply line in case a leak is detected.
