Whether you're a homeowner or a renter, an automatic water shut off valve can help protect your property and minimize the potential for water damage.
These devices offer a simple yet effective solution, that, with just a touch of a button, or the help of a sensor, will swiftly shut off the water supply.
So in this guide, I'll be reviewing some of the top automatic water shut off valves on the market, considering their effectiveness, ease of use, and affordability.
What does an Automatic Water Shut Off Valve do?
An automatic water shut off valve is a device that detects leaks or excessive water flow and automatically shuts off the water supply to prevent further damage.
It helps protect against water damage by stopping water flow when it shouldn't be flowing, thus preventing costly repairs and potential flooding.
Types of Automatic Water Shut Off Valves
There are two types of products you can choose from when looking to automatically shut off water flow into your home
- An Integrated Valve Controller incorporates a valve mechanism to control water flow and can be directly installed into the pipes. Usually placed after the water meter or main supply valve, professional plumbers are best for the installation.
- Motorizing an Existing Levered Ball Valve: You can install this controller over the existing levered ball valve. They are less invasive and simply act as actuators that help turn the existing water valve. Installation is very easy and DIY-friendly. However, they need more clearance above the pipe and require a valve that has a long lever.
My Recommendation
My main recommended smart water shutoff valve is the Moen Flo Smart Water Shutoff.
This device monitors the flow rate and pressure of your home's water, detects leaks as small as a drop per minute, and can automatically shut off your water before a catastrophic leak occurs.
On top of that, it offers real-time alerts, tracks water usage, and provides unmatched whole-home protection.
The only downside to the Moen is it usually requires professional installation. So for the DIYer, as an alternative, I recommend the EcoNet Controls Valve Robot.
This device easily fits over an existing levered ball valve, eliminating the need for any plumbing. The Wi-Fi version of the EcoNet is probably the best for those without a Z-Wave network.
