leakSMART Water Leak Sensor

leakSMART Water Leak Detection Sensors- Add Sensors to Your LeakSmart SystemIf there is one brand of manufacturers which has always been consistent with the kind of products they churn out, we would definitely have to go with leakSMART. Not only are their products reliable, safe and secure, they are also highly innovative and integrate some of the latest technologies. The sensor is fitted onto your main water supply where it can easily detect any sort of excess water. If it detects any unwanted water leakage, it immediately notifies the user and sounds an alarm.

If paired with the shutoff valve, the water leak sensor will automatically shut off the main water supply as soon as it detects a leak; if not, then you will have to manually switch the supply off. We would highly recommend you to buy and pair the shutoff valve with the leakSMART Sensor in order to fully utilize all facilities that come with the system. It will also help protect your house against potential floods.

One of the useful aspects about this best leak detection equipment is that it is compatible with other smart home devices such as Samsung SmartThings, Nest, Wire and so on.

The Best Water Detection Kits: Buying Guide

Most water leak detectors work by using a water sensor. If the sensor gets wet, the device will send an alert and/or set off a water alarm. This is the case of a majority of the leak detectors. However, not all of them have the same features, characteristics, warranty and return policies, and lifespan. Here are a few things to always keep in mind when buying leak detection kits.

Number of Sensors


Some people might only be willing to afford just one sensor, and that’s okay. But most people would do better off with more, at least two sensors. Usually, one sensor in the main supply line can be sufficient, so you might not need any excessive products. But a general rule of thumb, one sensor per room is the most optimal. Most people choose to just install one detector for their bathrooms or kitchens, while others get the entire supply line rigged. Nevertheless, more sensors mean more security. But if you’re tight on the budget, we would recommend just getting one water leakage alarm for either your main line or just the bathroom/kitchen, more optimally in places which have a history of leakages. Water sensor alarm like the Buoy Water Leak Detection Equipment is a great choice as just one unit is sufficient for any household.


You don’t want to hang around with 32 leak detectors that weigh a ton. A good detector should be small,portable and only weigh around 5 pounds, even the bigger ones like the Buoy Detector. If the product is too heavy, then it will weigh down on the piping and might actually become a source of leakage. We don’t recommend buying one which weighs more than 7 pounds. Smaller sizes are much preferred, as they cost lesser too, and can easily be installed hassle-free.


It finally comes to this that even the best water leak alarms do not last forever. Every piece of equipment loses its efficiency over time, including water leak sensors. Almost all leak detectors last up to 5 years, although some newer and more modern ones claim to function for a whopping 10 years or more. It usually depends on the technology used. Detectors made of metal are prone to rust, and if the rust infects the water, then there are chances of contracting tetanus and other diseases. The best water leak detectors are made of resilient plastic, and do not degrade over time or contaminate the water. We recommend choosing one which has some great leak detection reviews, or has many certifications.

AC And Refrigerant Leak Detectors

After all, the plumbing isn’t the only thing that leaks. Coolants and freon can leak from AC and refrigerator pipelines too, and for that you don’t know how to detect leak in those appliances. Some newer but admittedly costlier models work as both ac leak detector and refrigerant leak detectors. These can be a bit more costly though, and AC and fridge leakages aren’t even fatal most of the times. But if you’re feeling comfortable with the extra feature and the price, then by all means buy one that works as best refrigerant leak detector with AC leakage detection function as well.

Auto Shut-Off Mechanisms

Automatic Shutoff Valve

We seriously recommend buying a sensor with an automatic shutoff mechanism. This might just save your life. So say you aren’t attending your phone at the moment and you a get an alert for a critical leak in your piping. If you don’t tend to the leak quickly, then things can get disastrous. An automatic shut-off mechanism keeps everything secure and completely shuts off your water supply is the leak is fatal. Many auto shut-off valves can be manually operated as well. Some may even let you add a water usage limit and shut off the supply if too much water is used. This is a great new addition, and a large number of brands sell the valves either separately or in packages. Getting a discount off of these will definitely be a plus.

The Software

The sensors and valves are just one half of a full water leak detection kit. The other half is the software. Older models only used to sound an alarm, but nowadays ever detector sends an alert to your personalized app. The software varies from brand to brand. Some provide a whole lot of features, such as temperature, water pressure, and valve regulation. Others allow you to shut off the supply with just a tap. We like those which provide a combo of a number of features and statistics. Some of these apps are paid for, and some require you to pay for a monthly subscription. If you’re low on cash, use the ones which have free apps and subscriptions. Don’t let capitalism compromise on your safety.


For most people, a good leak detector with awesome features is useless if they know they can’t afford it. Before going overboard with the price and buying something that you financially can’t afford, try going over all of your choices. The cheapest ones can cost as little as $20, whereas the highest ones can go up to 6 thousand dollars. But of course, most of the features on those are redundant. A decent sensor should cost around $50 or $100. Any more than that and you risk going over budget. If your budget is tight, then buy the ones which fall right under your limit. But be warned: a higher price doesn’t necessarily mean higher value. Many brands can cost a fortune and be pretty useless.

Extra Features

A leak detector that only detects water leaks is of little use. Newer models now feature temperature regulation, water pressure monitoring, usage and wastage monitors, and even allow you to customize the suitable temperature for the water. The most common one is thermal leak detector, which alert you when the temperature gets too high or too low, to avoid overheating, cracking of the plumbing, and frozen pipes. Some include pressure sensors too, to alert you of too much pressure, which can essentially lead to leakages. WiFi water sensor use a wireless connection and a specialized app to keep you safe and secure.

What’s in A Water Leakage Detection equipment Kit?

Although the parts can be bought separately, a whole kit usually includes:

  • Water leakage sensors/detectors (usually 1 or 2) (others can be bought separately).
  • A hub which connects the sensors and you.
  • Automatic shut-off valve.
  • Remote control (optional).
  • Sensor range extender.
  • User’s manual.
  • Warranty card.
  • Batteries (Lithium-ion or other).
  • Software (to be downloaded).

For a leak detection kit to work properly, however, the following is required:

  • A smartphone which can support the software (usually Android 4 or iOS 5).
  • A decent Wifi connection (specifications vary).
  • A specific power supply between 100 and 240 V.
  • A DC or AC transformer.
  • Above ground water supply line (some work as underground waterleak detector too).

The main sensors work by detecting even the tiniest bit of moisture. They either alert you throughyour phone or by sounding an alarm. Some also detect the temperature and pressure, and monitor water consumption and wastage. The sensors are the main detectors in these kits, and their efficiency depends on power, support, and mechanism.

The hub is a communicating center between you, your sensors, and the auto shut-off valve. It takes in wireless input from the detectors and transmits it to your smartphones. A broken hub can mean bad news, so be very careful and cautious when handling one. If the hub is broken, then no leaks will be detected, and you might be under potential threat.

The auto shut-off valve shuts off the water supply in case of a critical leakage or water loss. This is a very handy equipment, as most owners are not around to always fix a leak immediately. Most valves can also be remotely operated and controlled manually.

The leak detector range extender works by amplifying the signals of the sensors to broadcast them across a wider range. This device is entirely optional and only a few brands, such as LeakSmart, provide it. The extender helps to allow you to control valves and detectors at even larger distances, and is perfect for buildings with multiple floors or more average.

The batteries are usually included in the packaging and are typically Lithium Ion. The power and voltage differ, but most are suitable for small products like the sensors and the hub. Some require the product to be plugged in into an AC or DC power supply source or adapter.

The software is a great way to monitor your water consumption. Not only does it send alarms and alerts to your phone, but it also gives you proper statistics regarding the temperature, usage, wastage, pressure, and sometimes even potential hazards based on readings from each and every sensor.

Why do I need a water leak detection system?

Although they may seem innocent, even the tiniest leakage in the water supply system can develop into a flooding. If you’re having second thoughts, then you might want to also consider the fact that a leaking pipe can lose up to 20 gallons of water per day, which can lead to severe water wastage and water loss. Leak detectors are a great choice for anyone. Smart leak detectors connect directly with your phone, whereas the regular version just sets off an alarm.

How long should I use a sensor for?

Although brands may claim that their products can last for a decade, we recommend getting your system checked every month, and completely replacing it every year or so, or whenever you find convenient. Remember that this is no ordinary appliance like a washing machine or a bathtub. This device is meant for your security, so replacing every year is the best choice.

Are automatic shut-off valves necessary?

While not entirely required, and many users can overlook them due to budget, we find that buying one would definitely be in your favor. For one thing, they do the main job for you: prevent a disaster. They can be very handy for when you’re not attending your phone, or when the hub stops working or the app malfunctions.

Where can I get a decent leak detector?

You can order online, either through the official website of the company or through Amazon. If you go order from the website, you know you will have the authentic product and might even avail some discounts. Amazon also offers some great options like free delivery and occasional discounts.

Following the multiple flooding and water loss incidents, companies started making leak detectors, and we can’t be more thankful for that. Leak detection is just as important as smoke or carbon monoxide detectors, and they have changed our lives in so many ways. You can read more water related product reviews here.

For those people who think that it is useless and unnecessary to have a leak detector in the house, consider the fact that water damage is 5 times more likely to bankrupt you over robbery and fire damage. And almost 40% of all homeowners suffer from excessive water loss, which makes their household water bills skyrocket. This, in turn, makes them lose their focus in other parts of their lives, such as their work, school, college, social life, and of course, mental health.

If you plan on not buying a detector because you think you will save on money, then you’re wrong. The initial cost may be frightening, but sure enough, you will save tons on insurance, water bills, wastage, and most importantly, human lives. So don’t just sit there and wait for a disaster to come gushing out of your plumbing. Get a spectacular water detection unit right now and save tons of bills and money.
