The Buyers Guide To The Best Water Leak Detectors

Before we start diving into water leak detectors, we must understand what to look for. This is why I’ve created this buyer’s guide to help you on your way

Here are the things I looked out for before purchasing my very own water detectors.

Price

Water leak detectors can vary in price for a few reasons, it could be due to the branding, or because it offers more features than the rest. Either way checking the price will give you a rough idea of how the product will perform at detecting water damage.

Protocol

If you've already started your smart home, there's a good chance you already have a home hub. And if you want your water leak detector to link up, then you need to think about the protocols it accepts. For example, a Wink Hub would require a Z-wave or Zigbee protocol.

Hub Requirement

Some water leak detectors run solely through WiFi, which means no hub is required to get the devices up and running. If you don't have a home hub, then finding one that works without a hub will be the best option. Just make sure you check its compatibility.

Integrations

Some water leak detectors can integrate with third-party products like IFTTT, but why is this beneficial? Well, it can help you set up recipes; for example, if the alarm is triggered, you can have the lights turn to help you wake up. Or the best feature is having the sensor communicate with your smart water shut off valves.

Size

Depending on where you're planning to place your water leak detector will depend on the size you'll require. You'll need a water leak detector that is small enough to fit where ever necessary. Unfortunately, water leaks start in the most awkward places.

Siren

If you lose internet connection for whatever reason during a water leak, you won't receive any notification to your smartphone, which let's face it, isn't ideal. Having a built-in siren is very beneficial; you'll be notified of any water leak by a loud siren filling the room.

Extendable

It's never guaranteed that a leak is going to happen in a specific place, which let's be honest can be a bit of a nightmare. Luckily smart water leak detectors like the Honeywell Lyric can be extended, meaning you can cover the whole perimeter of the room or wrap it around pipes.

Additional sensors

Some leak sensors don't just detect water leaks; they can cover a whole range of conditions. Some of these include humidity sensors to help find moisture before mold starts to grow. You can also find temperature sensors to help you locate frozen pipes before they burst causing damage to your home.

The Best Water Leak Detectors

Hopefully, the buyer’s guide has helped you understand a little bit more about water leak detectors. Now it’s time to use this knowledge to choose to find your smart water leak detector.

What Other People Say

The device was a lot nicer than they expected and worked very well. They liked that the three probes were spring-loaded; it meant they were always connected to the floor. You could also hook up to a 12 v DC power source, although they hadn’t tried this yet.

Another customer loved how well it connected to their Samsung SmartThings Hub. It enabled you to receive text messages on their phone. They were having trouble with the battery life at first this use solved by placing a plastic sheet underneath. For some reason, their floor was draining the battery.

I choose this device for a couple of reasons, the first one being it could connect to my Samsungs SmartThings hub. This enabled me to set IFTTT recipes to turn on lights in my bedroom to wake me up when a leak is detected; it would also send me text messages to my phone.

You might be wondering why I didn’t choose the SmartThings smart water sensor, considering how much cheaper they are. Well, for me, this flood sensor outperformed them, the spring-loaded gold plates held to floor better, thus it could detect leaks easily.

Once the leak is dealt with, it will send you an “All Clear” message.

If you’re at home, there’s no need for messages; instead, you’ll hear a loud siren to give you warning of the water leak. 

The best thing about this smart water leak detector is, it can also detect humidity and temperature. 

This can help owners identify areas mold, or frozen pipes before they burst.

They had brought the devices six months ago after their basement had flooded. They placed their new device next to the sump. Fast forward, they received an alert saying water had been detected, they rushed home to find the water was one inch from the top of the sump.

#3 – Govee Water Alarm

BEST BUDGET

Govee Water Alarm 100dB

Their water leak detectors have two groups of smart water sensors, and theses can be found at the top of the water leak sensor and the bottom. 

This means the water sensor can detect drips from pipes at the top and floods at the bottom, giving you the possible protection.

The whole device is completely wireless, making it super easy to install.

It’s a simple case of pulling the blue tag out of the battery and placing it where ever you need it. 

And the small size means it can fit anywhere without taking up too much room.

The water sensor comes with a built-in siren, which releases a loud alarm at 100 dB, this is more than loud enough to be heard from the basement. 

Once the leak is found, you can press the mute button to turn it off. The whole unit is completely sealed and waterproof to give it a long life.

  • Built-in 100 dB siren
  • 6-Month battery life
  • Dimensions: 3.5"×1.8"×0.9"
  • Detect water height: 0.5mm

What Other People Say

They used the device in the basement as a “just in case” measure. They were very pleased with how easy it was to set the leak detector up. To get all set up on their phone, they had to purchase the smart water leak detector kit, but this allowed them to pair multiple devices.

Another customer was also pleasantly surprised by how easy it was to set up. The device was small enough to place anywhere, and it was highly sensitive to water leaks. They were more than happy to recommend this device to friends and family.

Final Verdict

For the price, you really can complain about this device. Yes, it may not have all the fancy features, but it does exactly what it says on the tin. It could detect leaks efficiently and quickly and produced a loud siren that can be heard from the basement.

It would have been nice if you could receive notifications to your mobile phone without having to buy a secondary device. But, as I said, the price is ridiculously low. Once you’ve added the adapter you can get full updates to your phone, this will set back a further $20.

What We Liked

  • Loud alarm
  • Works in dual mode
  • The battery lasts 6-months

What We Didn’t Like

  • Requires a kit for phone monitoring

They promise to deliver a reliable and well-performing piece of kit that helps to keep your home safe of damage. It’s powered by a battery and uses low energy consumption.

They claim their water sensor can operate in standby by for over six months before they need changing, but this does depend on how many times it detects a leak.

#5 – SmartThings Leak Sensor

They designed the SmartThings leak sensor to give you instant alerts to your phone at the first sign of a leak. 

It helps you get on top of any leak quickly and efficiently before your home starts to flood. 

Once a leak has been detected the siren is activated to alert you. The sensor uses a Zigbee protocol to connect to your smart hub quickly and efficiently.

By combining the sensor to your smart hub, you can program your smart lights to turn on when the alarm has been sounded. 

All of these features are designed to give you the best chance of catching the leak before it gets too bad.

The SmartThings leak sensor doesn’t just detect leaks; it will also monitor the temperature too (operating temperature of 32°F to 104°).

The SmartThings leak sensor can shut down all your smart devices when moisture has been detected for an added sense of security.

Key Features

  • Zigbee protocol
  • Working range: 50-130 ft
  • 1-Year warranty
  • Operating temperature: 32-104°
  • Dimensions: 2.3” x 1.5” x 0.9”
  • Needs a SmartThings Hub

What Other People Say

One customer had placed the leak detector next to the sump pump in their basement. And when the sump stopped doing its job, the alarm has set off, and push notifications were sent to their smartphone. The alarm was more than loud enough to wake them up; this allows them to check the water leak before any water damage occurred.

Another customer couldn’t believe how easy the device was to set up, although additional programming features got a little tricky. They have had the device for a few months now, so far, no leaks. But they know the device works due to the alarm getting set off when the cleaning lady mops the floor.

Final Verdict

Here’s the thing, the device isn’t bad; it’s just not great; it’s a relatively simple water leak detector; you shouldn’t be too surprised when you notice the low price. The other thing is you need a SmartThings hub to control it. So, if you don’t already own the hub, that’s another additional cost.

I personally wouldn’t suggest it to someone that hasn’t already got the hub, but if you have, they are pretty solid devices. It has no trouble picking to detect leaks or detecting humidity. So, if you have the SmartThings Hub and you’re looking for a cheap and straightforward detector, this might be the device for you.

What We Liked

  • Great third-party integration
  • Easy to install
  • Works with Alexa
  • Good battery life
  • Temperature and leak sensor

What We Didn’t Like

  • Requires a SmartThings Hub
  • The siren isn't audible
  • No humidity Sensor

But, This Is The Best Water Leak Detector

The best water sensor has to be the Honeywell Leak & Freeze Detector. 

It offers a whole range of capabilities, from geofencing to humidity detection. 

One of my favorite features is being able to extend the leak detector. With the right attachments, you have the potential to detect leaks in a 500 ft perimeter.

Honeywell Wi-Fi Water Leak & Freeze Detector

The water sensor was small enough to fit under all washing machines, and the 4 ft extender could wrap around the pipes to detect water leaks.

Another standout component was the App; it warned you quickly when a leak is detected and was intelligent enough to know who was the closest person to your home. As it goes for battery life, it was the best performing; the battery could last three years on standby.

There you go, if you’re looking to protect your home, then these water leak detectors are a great way to go. If you think I missed anything out, comment below, and I’ll get back to you.
