There are lots of smart water leak and flood sensors available now that can be connected to your smart home. These devices will quickly and accurately alert you to any potentially damaging water leaks but fall short in two key ways; they can’t do anything about the leak, and they only monitor a specific area where they are placed.

For a truly smart home response, we need a system that can intelligently take action when a leak is detected, and that’s where automatic water shut off valves come in. When my dishwater inlet valve cracked and started leaking into my kitchen cabinets I didn’t know anything about it until the floor on the other side of the wall became squishy.

Thankfully it was a slow leak and I was able to get things dried out, but it could have been disastrous. Since then I’ve looked at getting some wireless water shut off valve in place to prevent it happening again, or at least warn me something is up before it gets that far.

I’ve spent around 40 hours researching the various products on the market, and I’ve come up with the list below. Many of these products still fall short in key ways, but I’ve determined the best overall product, plus alternatives for WiFi, Z-Wave, budget, and outdoor options.

Importantly, I’ve split things into two distinct groups, as there are two very different automatic water shut off methods you can take here. Let’s start with defining those two approaches, then we’ll look at devices in each category.

Types of WiFi Water Shut Off Valve

Inline WiFi water shutoff valves

Arguably the best approach is that taken by inline smart water shut off systems. These are installed into the main water line into the house and usually include some sort of water flow monitoring and leak detection technology so they can respond on their own to automatically shut off the water supply with no dependence on anything else.

These systems have the key advantage of offering whole-home protection, in that they can detect a leak anywhere in the house pipework and shut off the water to all of it. This covers you not only for faulty appliances and taps, but burst pipes and leaks in other unexpected places. As a bonus they can also track water usage and provide reporting in their relevant app.

The downside is you really should have these professionally installed as you’re dealing with the main inlet line, and they can be quite expensive devices as well.

Add-on WiFi valve controllers

The cheaper, simpler approach is to use a WiFi valve controller to shut off the water supply. These devices sit on top of an existing quarter turn ball valve and can physically turn the lever for you by remote control. This obviously avoids the need for pipe cutting or plumbers.

They are dumber in that they just do the on/off part, and rely on connected leak detectors of some kind to alert the system to a leak. While you can typically have many such leak detectors, you’re still limited to responding to leaks in monitored locations, and a burst pipe in the ceiling or floor is unlikely to get noticed for some time.

This approach is not all bad though, as it provides less ambiguity as to when the water should be turned off. The leak detectors are accurate and that means the valve can be shut off in seconds without the system worrying about whether it’s normal usage or not, or shutting things off when you don’t want it to.

Best In-Line ValVe Overall

flo-by-moen.jpg

Flo by Moen

✔ Fits 3/4” to 1-1/4” pipe
✔ WiFi, no hub required
✔ Supports Alexa and Google Assistant
✔ Internal water leak detector
✔ Optional battery backup
✔ Outdoor rated (IPX5)

✘ Requires power outlet (25’ extension optional)
✘ Subscription required for detailed reports
✘ Internet required for app control

What I Like

After a lot of consideration I’ve given the best overall WiFi water shut off valve to Moen’s Flo system. It simply offers the most complete package with a good range of pipe sizes, smart home platform support for Alexa and Google Assistant with no hub requirements, battery backup, and outdoor capability. This also works with Ring Alarm which is a great addition for automated security responses to detected leaks.

It has automatic water leak detection built in, but also includes the option to use Moen’s leak sensors for extra protection and reliability. The automatic sensors monitor your water usage and try to detect unusual water flow that would indicate a problem.

This offers the advantage of being able to identify even slow leaks in toilets or hidden pipes that might otherwise go unnoticed for long periods, and presents it in a slick modern smart phone app with easy to use controls and event logging. You’ll also get very detailed and accurate reporting and analytics, but that comes with a catch.

Potential Concerns

That catch is that to get more than basic data reporting you’ll need to pay Moen’s monthly subscription. It’s not huge, but some people understandably see this as a cash grab given it’s an expensive piece of hardware already. Even so, Moen do throw in a deductible payment if you have an insurable incident, and an extended warranty for that extra fee.

A common concern with these inline water shut off valve types is their tendency for false positives. Like other models, the Flo uses pressure and flow rate sensing to ‘learn’ the normal usage patterns of your home’s water supply, and then alerts when something seems abnormal. Moen doesn’t offer any way to help this learning process, so you have to trust that it figures it out right, which it sometimes doesn’t, leaving you high and dry until you manually turn it back on.

Best Value In-Line Valve

leaksmart-auto.png

LeakSmart Auto Shut Off

✔ Fits 3/4” to 1-1/4” pipe (different models)
✔ ZigBee - needs compatible hub
✔ Supports Nest, Wink, IRIS, SmartThings
✔ Wireless water leak sensors
✔ Included battery backup

✘ 120V power required
✘ Needs LeakSmart Hub for sensors
✘ Indoor rated (outdoor enclosure available)

What I Like

While also an inline system, LeakSmart’s automatic shut off system is simpler than the others here. It doesn’t use an internal leak detector and instead relies on their own brand of wireless leak sensors. These all talk to each other via the ZigBee protocol, which makes it compatible with any smart home hub that offers that communication.

You can use the LeakSmart System Hub to provide this connectivity and join it to your WiFi, or you can use your own if you have one. I like the flexibility this offers for smart home users over being stuck with the limited platform integration offered by just voice assistants.

While the device itself is not rated for outdoor use, LeakSmart do offer an enclosure you can use if you need to install it outside, and it also includes a backup battery like the Moen so you’re not stuck in a power outage.

Potential Concerns

Not having internal flow sensors does mean you’re not getting whole home protection with this one, but it’s also a lot cheaper, even with the other system components, and you can expand the number of leak sensors to better catch a water leak.

I’ve seen some customer reports that suggest it may not last as well we one would expect, but that’s hard to gauge from only sporadic records so I’ll just note it here.

Best Z-Wave In-line Valve

leak-gopher.png

Leak Gopher by Leak Intel

✔ Fits 3/4” to 2” pipe (different models)
✔ Z-Wave Plus - controller required
✔ 10 year warranty

✘ 110v power required
✘ Indoor rated only
✘ No built-in sensors

What I Like

If you’re after something to use with a Z-Wave system, the Leak Gopher is your best bet for an inline install. It’s reasonably solid with a strong motor and a 10 year warranty. Again, as it’s just the water shut off valve you’ll need some leak sensors connected to your Z-Wave system to trigger it.

While not WiFi and requiring additional infrastructure, Z-Wave still provides a wireless water shut off solution that offers some advantages over WiFi based models.

Potential Concerns

No whole-home protection here either, and some of the included valves have had poorly cut thread on the pipe connectors, leading to some installs being more difficult than they should have been. It’s also quite pricey for what you get, but there aren’t many Z-Wave options in the inline category.

Alternative WiFi Shutoff Valve for Outdoors

phyn-plus.jpeg

Phyn Plus

✔ Fits 3/4” to 1-1/4” pipe
✔ WiFi, no hub required
✔ Supports Alexa
✔ Internal water leak detector
✔ Outdoor rated

✘ 110V/220V power required
✘ Plastic fittings
✘ Internet required for app control

What I Like

The Phyn Plus is a slick looking automatic water shutoff valve, but more importantly it’s outdoor rated, which makes it worth a look if you need that. It can also handle a 220V outlet, which gives it a bit more flexibility.

Like the Moen it includes pressure/flow sensors and a learning system to detect leaks. Unlike the Moen Flo it does occasionally check with you if it’s correct with it’s assumption, and allows you to override. This could result in it better handling potential water leaks automatically without causing some household angst.

Potential Concerns

The additional user input to the learning system is welcome, but it still suffers from issues around false positives as with other flow based detection systems.

I’m also not a fan of it having plastic fittings on such an expensive device. These are so easy to damage during install if you’re not careful.

It’s also been noted that while it does have a manual override in the event of a power failure (there’s no backup battery here), it requires a fiddly insertion of a specific screw driver. This can be awkward to get to, and to get traction on the screw to turn it.

Alternative WiFi In-line Shutoff Valve

grohe-sense-guard.jpg

Grohe Sense Guard

✔ Fits 3/4” pipe (1” adapter available)
✔ WiFi, no hub required
✔ Internal water leak detector

✘ 110V power only (27’ extension optional)
✘ Indoor use only
✘ Internet required for app control
✘ No smart home integration

What I Like

The Grohe Sense Guard is a smart looking automatic water shut off valve with very clear status indication via the ring light around the top edge, and simple manual controls in clear view. You do get whole home protection, and it’s WiFi connected, so no extra hardware is needed.

It’s a quality device, with good fittings for the price.

Potential Concerns

There’s no smart home integration, so you’ll be using only the dedicated smartphone app for control and alerts. That would usually put a device out of the running for me, but as it still offers remote app control I’ve chosen to include it for those who aren’t so interested in an integrated solution.

You’ll also need to check your pipe size as the Grohe doesn’t support many options, just the 3/4” and a possible 1” adapter.

Best Add-on Valve Controller Overall

econet-bulldog.jpg

EcoNet Bulldog valve robot

✔ Fits 1/2” to 1-1/2” pipe
✔ Z-Wave Plus - controller required
✔ High torque motor

✘ 110v power required
✘ Indoor rated only
✘ No built-in sensors

What I Like

I’ve given the EcoNet Bulldog Valve Robot the top spot in the add-on valve controller category primarily because it is a well built device that will get the job done with the most powerful motor on the market, so it should be able to handle your water supply via your existing levered ball valve.

It’s exclusively Z-Wave controller, but uses the newer Plus standard for added security and reliability, and that also means you can create deeper integrations with your other smart home devices if you use that protocol.

EcoNet says it is rain resistant, but they recommend protecting it nonetheless. You'll also note the mounting bracket is around the valve body, not the neighboring pipe like other models. This is preferable as it eliminates undue stress on the pipe joints when the motor is operating.

Potential Concerns

The biggest issue with this one is that it’s only suitable for North America. This is due to the different radio frequencies used for Z-Wave around the world.

Best WiFi Add-on Controller

leaksmart-valve-controller.jpg

LeakSmart Valve Controller

✔ Supports Alexa and Google Assistant
✔ Included Battery backup
✔ Kit includes hub and sensors
✔ Easy snap-on install

✘ 110v power required
✘ Indoor rated only
✘ LeakSmart Hub required

What I Like

LeakSmart have a few products on the market, and we’ve already looked at their inline offering above. This automatic water valve controller provides an alternative solution, and while it’s not the powerhouse that is the EcoNet Bulldog controller, it does offer a comprehensive package through their starter kit. That includes the controller, the hub, and three leak sensors all for a pretty reasonable price.

Through the hub you get support for Amazon Alexa and Google Assistant, and the device includes a battery backup, which is always a welcome addition. If you’re not running a Z-Wave system, this is the most feature packed option.

Potential Concerns

You’ll need to ensure you have a free turning ball valve on your water supply pipe as the motor is not as strong, nor is the pipe mount. You’ll need to take care that it’s secured well to avoid issues.

Budget Add-on Controller

vaticas-smart-valve.png

Vaticas Water Valve

✔ Fits 1/2” to 1-1/4” pipe
✔ Tuya based (supports Alexa and Google)
✔ WiFi, no hub
✔ 12V DC 1.5A barrel plug

✘ Weak motor
✘ No built-in sensors

What I Like

For the truly budget conscious there is often a cheap alternative, and the Vaticas Water Valve is it. This is one of numerous, largely identical, generic automatic water shut off valves that are sold under various brand names.

They’re cheap, fit a variety of existing ball valves, and operate through the widely used Tuya smart home platform. Through Tuya you’ll get some degree of Alexa and Google integration, but it’s not going to be a lot.

Being simple WiFi, and offering a cable ending in a barrel plug you’ll be able to use these anywhere in the world with a suitable AC/DC power pack. It comes with a US style one, but it’s easily swapped out for another format.

Potential Concerns

Being a cheap product from an otherwise no-name brand you shouldn’t expect anything in the way of support. You’ll also not get a best of breed product, with customers noting the motor is pretty weak, and the clamp is also a bit simplistic and may not hold well depending on your install situation. At least it clamps to the valve instead of the pipe.

Best Outdoor Add-on Controller

fortrezz-valve.jpg

FortrezZ Valve Actuator

✔ Actuator only, needs custom valve
✔ Z-Wave - controller required
✔ Motor is outdoor rated (25’/50’/75’ cable options)

✘ North America only
✘ No built-in sensors

What I Like

I’ve included the FortrezZ Valve Actuator as a Z-Wave option that can be used outdoors, as there aren’t many for that use case. The FortrezZ system requires multiple parts, so it’s a bit complicated, and pricey, but if you need outdoor control for your water supply then you don’t have many options.

Shown is the control box, that has to be inside near a power outlet. You connect that to the valve motor via a cable that comes in various lengths depending on your needs. The motor is the outdoor rated part. The additional catch here is the motor doesn’t use existing ball valves. Instead you have to buy a suitably sized valve add-on separately and attach it directly to the motor unit.

Potential Concerns

It’s not clear if this is a Z-Wave Plus device, but it doesn’t look like it is to me. That’s a bit disappointing these days, so hopefully they release an upgraded version soon.

It’s also US-only due to the Z-Wave frequencies being used. The system doesn’t come with leak sensors of it’s own, so you’ll need to use other devices on your Z-Wave setup for leak detection to trigger it.

Alternative Add-on Valve Controller for Z-Wave

dome-shut-off-valve.jpg

Dome Shut Off Valve

✔ Fits 3/4” to 1-1/2” pipe
✔ Z-Wave Plus - controller required

✘ 110v power required
✘ Indoor rated only
✘ No built-in sensors
✘ Lacks torque for some valves

What I Like

The Dome Shutoff Valve is one of the better known valve controllers, and plenty of people swear by them. This is another Z-Wave Plus controller, like the EcoNet, but is strictly indoor use only.

These are reliable and straight forward to use, so they’re certainly worth including here.

Potential Concerns

The biggest drawback, and why the EcoNet Bulldog rated better, is the motor size is considerably smaller (and thus weaker) which means it may not work well in your situation. You’ll want to check your water supply valve operation beforehand to see if it’s going to put up too much resistance.

Alternative Add-on Valve Controller for Wifi

guardian-leak-prevention.jpg

Guardian Leak Prevention

✔ Fits 1/2” to 1-1/2” pipe
✔ WiFi, no hub
✔ Easy clamp install

✘ 110v power required
✘ Indoor rated only
✘ No built-in sensors
✘ No smart home integration

What I Like

For an alternative that doesn’t need Z-Wave, the Guardian Leak Prevention system offers a solid WiFi only option. It has the benefit of securing with easy to install clamps at BOTH ends of the device, which ensures you won’t have any rotational slippage problems. Those clamps also support a good range of pipe sizes, more than many other models do.

A water leak will be identified by Guardian’s own wireless leak detectors which offer a 15 year battery life, and you get these included in the pack.

Potential Concerns

With no smart home integration you’ll need to factor in enough of these to cover your risk areas, and it’s only rated for indoor use.

Questions you may have

What is a WiFi water shut off valve?

All homes have a main shut off valve that can isolate the house from the water supply. A smart water shut off valve combines some sort of sensors to detect potential leaks and allow a motorized valve to automatically shut that supply on it’s own.

The term ‘wifi’ in this case refers to general wireless communication, which could be conventional WiFi or another radio protocol such as Z-Wave. It simply refers to the device being wireless and not requiring any sort of signal cabling.

These devices can provide valuable protection from major or minor water leaks in less visible places, or when you are out of the house and unable to respond to an emergency.

Some systems use flow and pressure sensors to try and guess ‘abnormal’ water use, while others use a number of individual leak detectors that can be placed in areas of concern, such as the laundry, basement, kitchen, etc.

Are wireless water shut off valves worth it?

Yes. 37% of US homes have suffered water damage, with an average insurance claim of over $6000. 14,000 people every day suffer a water emergency, and that’s just the serious ones. Even if you don’t suffer a damaging event, leaks from US households are common, and 10% of homes leak over 90 gallons a day. Freezing temperatures causing pipe bursts, corrosion, and valve wear can easily end in an unexpected water leak.

That adds up to a lot of wasted water consumption, and money. Even the highest priced automatic shut off valves will pay for themselves fairly quickly, and you may even get a discount from your insurance company for having one installed.

You can get some peace of mind from smart water leak detectors, but these will only tell you there is a leak. You’ll have to be in a position to stop it yourself, and that’s not always possible in time.

How much does it cost to install an automatic water shut off valve?

Wireless water shut off valves can vary significantly in price, from around $50 all the way up to nearly $1000. On top of that, you may need to pay a plumber to install it if you got for an inline model that can protect the whole home. It’s not usually a big job, so you’re probably looking at an additional $100-$200.

What happens if your internet is down?

WiFi based smart valves will typically rely on the company’s servers for remote control via their app. This is not ideal as you are dependent on a third party for your product to work properly, or at all. Thankfully the basic shut off functionality of all of the valves in this list will still work if your WiFi is down, but you won’t have manual control via the app, or any alerting notifications.

Valves that use a dedicated smart home communications protocol, like ZigBee or Z-Wave, will fare better as they communicate directly with your smart home hub and any sensors you may have connected to it. These systems provide ‘local control’, which means they don’t need the internet at all to function. You will still lose alerting notifications when you’re away from home if your internet is down, as they still need a way to get that data to your phone.

The Wrap Up

If you’re looking for a comprehensive solution for leak detection and whole home protection, the Flo by Moen system is the best WiFi water shut off valve option. Comprehensive features, indoor and outdoor usage, and the option to use either the inbuilt flow sensors or enhance it with water leak detectors as well. Moen are the only brand to go with a subscription model so far, but you can use the system just fine without one, you’ll just lose some of the detailed usage reporting functionality.

If the subscription or the price puts you off, I’d recommend the LeakSmart Automatic Shut Off system. While not a whole home solution, it provides more smart home integration options, and an extensible sensor network for a much lower price.

Moving away from the inline options, you can utilize your existing ball valve with a motorized valve controller from EcoNet. Their Bulldog valve controller is tough and well built, but does need a Z-Wave controller to be of use.

If you don’t have Z-Wave, then I’d look at the LeakSmart Valve controller instead, it uses their LeakSmart hub to provide plain WiFi connectivity, and can tie into the same sensor system as their inline model.
