Shopping guide


If you don’t know much about this equipment, this guide to buying the best leak detector probably contains relevant information that can help you choose a device that is easy to install, use and timely when activating its alarms.

Leak detection system

When you come across any comparison of water leak detectors, you will notice that there are teams that use different methods to do the job, so it becomes one of the main features to review before purchasing any model.

Equipment for domestic use to detect water leaks can be direct contact or through hanging sensors. The former have detectors on their legs, so when they come into contact with water, this activates alarms and notifications. They are one of the easiest systems to use, as well as to configure to install them at home.

The second are detectors that have sensors connected by a cable. In general, these types of models are installed near the dishwasher or washing machine, for example, taking care that they are at the right height so that the sensor has contact with the floor. If one of these machines suffers a spill, the water will reach the detector and it will emit the signal.

On the other hand, if you are interested in acquiring a model for professional use or to identify leaks in internal pipes, you may have to consider ultrasound or vibration detectors, since with these systems it is possible to identify internal breaks for repair.

detector design

The design of the water leak detector is relevant if it is going to remain visible and, if this is the case, you can find options that have a discreet aesthetic to be installed in the kitchen or bathroom, for example.

The models for domestic use are usually made of plastic, since it is a durable material, resistant to water and easy to maintain so that you can have your detector in good condition at all times. In addition to this, you cannot ignore details such as its size and weight, since they are decisive in finding the right place for its installation.

Manufacturing materials

When it comes to water leak detectors, it is very important to consider the manufacturing materials of the device, precisely because it is designed to detect this type of incident.

Water can be corrosive, so a metal leak detector, for example, is more prone to wear and rust after a while, so options made from plastic or stainless steel are the most recommended in these cases.

Now, if you are purchasing an ultrasound water leak detector, in these cases, we do advise you to choose equipment that offers a robust and ergonomic casing. These systems are more complex to use, so they can have a big impact on how much a detector costs. However, these types of models are designed for professional use and hence their capacity and price.

Alarms and notifications

Since we are talking about water leak detectors, it is important to consider one of their main functions: to warn that the incident is taking place.

Today’s water leak detectors can be equipped with various notification systems, which can be visual, audible or remote. Some models even have all of these methods to ensure that the person has been notified of the situation.

In this sense, detectors for domestic use have alarms that could be regulated in terms of volume, as well as light indicators that can be turned on or off as desired. In addition, if the system has a large capacity, you could also determine the level of water that it must detect to activate the alarm.

Units capable of sending alerts remotely cannot be overlooked either. These detectors are linked to your home network in order to synchronize with special applications, responsible for sending notifications directly to your mobile phone in case you are not at home.

Installation requirements

Finally, we advise you to study the installation requirements of the water leak detector before investing money, since, depending on its model, it may need particular inserts or locations to work.

Likewise, you should also bear in mind that they can use batteries, rechargeable batteries or connect directly to a power outlet to turn on, so it is essential to have these elements on hand to avoid inconveniences during assembly.

Frequently asked questions


Q1: How to use a water leak detector?

Domestic water leak detectors are very easy to install, since they usually have an adhesive on the back that allows you to place them on the wall so that the sensor can be raised to the required height. Afterwards, all you have to do is turn it on and adjust the volume of the alarm or any other notification system it has.

In the case of water detectors that do not have hanging devices, these can be placed directly on the ground, since the sensors are located at the feet of the equipment. These, when detecting the presence of water, will be activated, either by sound or light warnings or messages to the mobile phone.

Q2: How does an ultrasonic water leak detector work?

An ultrasound water leak detection system uses ultrasensitive detectors capable of identifying frequencies greater than 20 Khz, which are impossible for the human ear to detect.

This type of detectors have an ultrasound sensor that must be placed on the wall or the floor depending on how the internal pipe is installed. In the event of a leak, the vibratory oscillations of the change in the water flow can be identified by the equipment.

Thanks to this information, you will be able to follow the wave oscillations to find the origin of the frequency alteration, which, in turn, will allow you to find the fault to solve it.

Q3: Where to install a home water leak detector?

Water leak detectors designed for domestic use are usually designed and recommended to be installed in places where there may be water spills.

For example, you can install your detector near the washing machine to prevent any spills, as well as in the kitchen in case the dishwasher does not work properly or the refrigerator defrosts without activating this function. On the other hand, many users also choose to place it near the waste water outlet of the air conditioning system to know when to empty the tank before it overflows.

In this case we are focusing on detectors that have sensors, which can be placed directly on the wall as long as the sensor is at the right height to detect the leak.


Q4: How far away does an ultrasonic water leak detector work?

Water leak detection systems that use ultrasound can vary in terms of the identification distance, since this value depends on the sensitivity of the sensors, which can range from 1 meter to more than 10 or 20 meters in some cases.

Q5: How to calibrate a water leak detector?

The calibration of this type of instrument must be carried out by a technical staff that has the knowledge and the necessary equipment to do it properly. If not, there is a risk of damaging the detector, as well as affecting the components that work with the sensors responsible for identifying faults in the installations.

Therefore, if you consider that your water leak detector is out of calibration, it is best to contact customer service personnel, so that they can give you instructions on where to take the equipment or if they will come to your home for its correct calibration..


Q6: What is a WiFi water leak detector used for?

The models of water leak detectors that have built-in Wi-Fi wireless connectivity give you the possibility of receiving alarms directly to your mobile phone.

These types of detectors work with an application that you must download to your smartphone and then synchronize it with the equipment. In some cases, the app will give you options for managing the sensor, either by turning it on, turning it off, or changing any of its settings.

At the same time, synchronizing the device with the phone will help you to register it with the home network, which is necessary so that it can send notifications when the sensors are activated.

Q7: Which is better, ultrasonic or conventional water leak detector?

The answer to this question will depend exclusively on your needs as a user.

In the event that you want a water leak detector for domestic use, you can consider the conventional models that are installed on the wall and have hanging sensors or also those that can be placed directly on the ground to detect the presence of water in your floor.

On the other hand, the models that detect leaks using ultrasound are more focused on commercial use, that is, for people who work in the plumbing and plumbing industry, since this tool has a greater capacity and is designed to identify internal leaks.. This type of leak requires more restoration or maintenance work depending on the severity of the break.
