Zircon Leak Alert Water Leak Detector

Zircon Leak Alert Water Leak DetectorThis leak detector is operates on a direct contact sensor. These Leak Detectors are meant to be placed underneath u-bend pipes or near places where leaks can happen. When the leak detector comes in contact with water, it provides a 90 decibel audio alarm. Each kit comes with five individual water leak detectors.

The sensor consists of two external metal contacts that have a current running through them. When water completes the connection between the two contacts, the completed circuit causes the alarm to sound. The sensors are meant for multiple uses, and are powered by a 9-volt battery. To reuse them, simply try the contacts and replace them where you need leak detection.

Ideas for placement include laundry moves, the basement, a garage, or the kitchen or bathroom. Make sure that when you place the leak alert, the metal contacts are facing downward and touching the surface. Depending on the spacing of the fibers, this device will even work on carpet. When the alarm sounds, it will continue to sound for up to 72 hours. In the event of a flood, the device will float and continue to sound an alarm until the battery runs out of power. Operating temperatures for this device are between 20 degrees Fahrenheit and 120 degrees Fahrenheit.

Features:

  • Size: 4.3 (L) x 2.4 (W) x 1.4 (D) inches
  • Weight: 1.5 pounds
  • Placement Type: Ground near leak areas
  • Power Source: Single 9v battery
  • Notification Type: 90 dB alarm
  • Sensor Type: Electrical
  • Response Time: Immediate
  • Sensitivity Levels: One

Zircon Leak Alert Smart Water Leak Detector

Zircon Leak Alert Smart Water Leak DetectorThis leak detector is also based on a contact sensor. This leak detector is meant to be placed on a flat surface near an area where a leak could potentially happen. This leak detector has two sensor contacts that carry a small electrical current. When both contacts encounter water, the circuit completes. Just completed circuit and then sounds a 105 decibel alarm with flashing LEDs. An email notification is also sent to whatever email address what setup when the device was installed. Emails are sent every 10 minutes for the first hour and then once every hour for as long as the battery lasts.

This leak detector is different because it has a built in Wi-Fi unit. When you set up the leak detector initially, it will show up as a wireless access point labeled as “LeakAlertWi-Fi_123456_78“. The eight digits will be randomized and specific to your specific leak detector. Once the detector is connected, an email notification setup link is processed. You can set up to five different email addresses. Any email notifications sent will contain the detectors name and the local time of the alert.

Because every detector has a different name, you can set up multiple detectors throughout your home or different properties. You can also adjust the individual names so that you can more readily identify when you receive an email from a specific detector. Additionally, you can receive an event log summary every 6 days. What’s the configuration is successfully completed, a confirmation email is sent.

This device runs off of one non-chargeable 3 volt lithium battery. If power should go out and your Wi-Fi router should lose power, emails will no longer be sent but the audio and visual alarms will still function. Because this leak detector relies on moisture connecting the two contacts, you can reuse this detector over and over again. Keep in mind, that if the lithium battery installed begins to run out of power, it will start to chirp much like a smoke detector that has a low battery. If you hear this, it will be much quieter than the regular alarm but you should replace the battery as soon as possible.

Leak Detector Buying Guide

Best Leak DetectorsNow that you have read five leak detector reviews on the best units available, it’s time to talk about what you should look for when purchasing one. One of the first things that we should talk about is how Leak Detectors work, we will cover both gas and water so that you can make a decision as to which is best for you.

After that, we’ll talk about what a leak can potentially cost and why you should get a leak detector in the first place. Then we’ll talk about six of the most important features of a leak detector and finally cover what causes leaks and how you can fix them.

How Leak Detectors Work

Everybody knows what a leak is. Essentially in any sort of fluid circuit, when some of the fluid comes out when it’s not supposed to, that’s considered a leak. For example, in your refrigerator, the refrigerant should always stay in the system. If it leaks, then that’s a problem.

A leak detector is primed to detect the particular fluid that is in your fluid system. This means water or refrigerant. These specific types of detectors vary between liquid and gas. Here are the various types of leak detection methods for the two.

Gas Leak Detectors

Best Leak DetectorsThere are four primary methods of detecting leaks in refrigerant. These are Electronic Leak Detectors, halide, soapy water, and fluorescent additives. Depending on the type of refrigerant, a specific method may be better than others. The various types of refrigerants can be broken down into three primary types:

  • CFC: Chlorofluorocarbons such as R11, R12, and R502
  • HCFC: Hydrogenated Chlorofluorocarbons such as R22, R408A, R409A, R411B
  • HFC: Hydrofluorocarbons such as R404A, R407C, R410A, and R134A
    Here is a brief overview of each type of leak detector and the subtypes found within each of them.
  • Electronic – electronic leak detector basically uses a flow of current and looks for a change in that current to detect the presence of a leak. There are four specific types oh, each with their own advantage and disadvantage.

a. Corona – a Corona discharge detector essentially pulls air through the electrical field around a wire. This electrical field is known as a Corona. When refrigerant or other gases in the air passed through the corona their presents causes the current in a wire to change. When the current changes, the leak detector picks it up and sounds an alarm. The primary disadvantage to this type of gas detector is that it does not differentiate between any of the various types of refrigerants. Additionally, it can also pick up unusual and higher concentrations of other gases that caused the electrical field to change.

b. Heated Diode – a heater diet detector uses a ceramic diode to generate an electrical current when it comes into contact with refrigerants. This current is then used to power the alarm. The primary disadvantage to this type of leak detector is that the sensor is sensitive to contamination. Fingerprint oil, and moisture causes V ceramic tile to require replacement after about a hundred hours of you. However, this type of detector is very precise and works well with certain refrigerants. Some of the more expensive Leak Detectors actually test themselves to ensure that the ceramic diode is still working appropriately and alert you if it needs to be changed.

c. Infrared – an infrared leak detector operates off the principle that refrigerant well absorb a specific amount of infrared radiation. When refrigerant passes through a gap. Infrared radiation is being broadcast through it will absorb some of this radiation. The detector will pick this up and then sound an alarm. The level of the alarm can be adjusted based on the amount of infrared radiation being absorbed. Because the more radiation absorbed, the greater the concentration of the refrigerant.

Additionally, because refrigerant absorbs a specific amount and frequency of infrared radiation, this type of detector is extremely accurate.
d. Ultrasonic – an ultrasonic detector works because when gas escapes through a narrow hole it emits a sound. In most cases this sound is at frequencies above what the human ear can detect, normally around 40 kHz.

The leak detector however is cued into these frequencies and when it picks them up, it will sound an alert. In some cases the leak detector will amplify them through a process called heterodyning. By placing multiple leak detectors in an area, then the position and placement of the leak can be triangulated. This technology has been around for a very long time. However it isn’t until recently that it has been inexpensive enough to use in handheld detectors. These detectors can find leaks that are as small as 1 psi.

● Halide – hey how I detector is powders butane and works much like a Bunsen burner. As air is channeled through the flame, the color of the flame changes. When used with CFC and HCFC refrigerants, the chlorine portion of the gas turns a flame either green or bright blue depending on the concentration of the leak. However, because the chemical reaction of burning refrigerants creates extremely toxic compounds, care should be taken when using this. Additionally, this type of detector should never be used with HFCs or HCs.

● Fluorescent – a fluorescent detector is used when a specific attitude has been added to the refrigerant. Because refrigerants also have oil when they’re added to systems, any leak can be detected by using a UV lamp. The primary drawback to this type of leak detector is that it requires that the leak is large enough that oil also leaks from the system. This is most commonly used with automobile air conditioners.

● Soap & Water – a soap and water test is the simplest gas leak detector. A mild soapy is combined with a small amount of water until a stick soapy mixture is formed. This mixture is then applied around Benz and other areas where the leak is suspected to occur. If a leak is present, bubbles will appear under the sub solution. The primary drawback to this type of leak detection is that it will not work if your refrigerant is operating under a vacuum. If it is, then your lines will just suck the sub solution in at any leak point which causes its own problems.

Water Leak Detectors

Best Leak DetectorsIt may seem pretty obvious as to detecting a water leak. After all, if something is wet, then something is leaking. However, a water leak can quickly cause enormous amounts of damage so a leak detector or water focuses on fast detection and immediate notification. There are primarily two ways of detecting a leak in a system. These are by either measuring the flow and looking for unusual changes or placing a physical sensor on the floor. When it comes to water leak detector ratings, the best are one of these two types.

  • Water Flow

A water flow sensor is a sensor that attaches near your water meter. It can use either ultrasonic or magnetic methods to track how much water is flowing past a certain point. These types of detectors are extremely accurate and can provide real-time tracking of how much water is being used by your system at giving given point in time. They detect leaks by looking for unusual activity. This can be either a large amount of water passing through because of a big leak, or a smaller constant and steady flow. Because you will know when water should be flowing because of your usage, any unusual water flow will alert you to the possibility of a leak. Of course, the primary drawback is that it doesn’t tell you where the leak is, just that one is present. As an added bonus, if you live in an area where water theft occurs, this type of leak detector would alert you to that as well.

  • Direct Contact

A direct contact leak detector is essentially an uncompleted circuit. A battery is attached to two leads which have a gap between them. The wires are attached to two metallic sensors on the surface of the detector. As water Flo’s and bridges the connection between the two contacts, the circuit is completed. Once this happens then the alarm goes off. These Leak Detectors can be as simple as just sounding an audible alarm, or they can be as complicated as alerting you through push notifications on a smart device.

The Hidden Costs of Leaks

Best Leak DetectorsYou might be wondering if you actually need a leak detector. After all, what’s the worst that can happen if a leak occurs? And in case of a water leak, if you have a leaking pipe, it can cost about $350 to fix it. That is just for the pipe itself. If the plumber has to accept it through drywall and cut a hole, that can add about another 200 to $500 depending on the location. However, if a pipe bursts, then you are looking at up to $4,000 in water damage and cleanup fees.

A water leak doesn’t just damage the floor. It also damages the drywall, the baseboard, and anything that you have on the floor, as well as cause mold in your home that can lead to bad air quality in your homes climate. If you have those issues you might want to look into getting professional help and invest in a good air purifier for mold to reduce the risk of the mold affecting the health of those living in your home. And when it comes to replacing the drywall, a 2 inch deep flood from a burst pipe can wick up the walls as high as 1 foot. That means you need to replace drywall about 18 inches high around your entire affected area. That cost is not insubstantial compared to the cost of detecting and isolating the initial leak. While homeowner’s insurance may help cover the cost of the repair, you have to then worry about the resulting increase in your premiums as well as the risk of even having your homeowner’s insurance cancelled.

When it comes to refrigerants, the danger is a little more insidious. Refrigerants like HCFCs and (in older systems) CFCs are toxic. They can poison you, your loved ones, and your pets if left unchecked. Breathing in Freon can kill you. Additionally, refrigerants are also extremely bad for the environment if left to leak unchecked.

But beyond the health and environmental dangers, a system that runs with a leak will start to encounter multiple problems. Low refrigerant can cause icing on air conditioners and excess wear and tear on the compressors. This means you will have to replace your air conditioner or your refrigerator’s compressor months or years before you should. In more extreme cases, you may need to replace the entire appliance.

Seven Important Features of Leak Detectors

When looking for your next leak detector, there are some things that you should be considering. Here are the top seven different features that are most important to us and to most users that we have spoken to. These features range from how portable a unit is or how easy it is to install. Cost was also a factor as well.

1. Portability

If your leak detector isn’t going to be installed permanently, then you want it to be as portable as possible. Nobody wants to lug around a fifty pound leak detector, no matter how accurate or sensitive it is. And even if your leak detector is permanently installed, such as a flow meter for water leaks, you want it to be able to be easily carried to and from the installation site.

2. Notifications

It doesn’t do any good to have a leak detector if it doesn’t tell you when one is happening. A notification should be loud or bright enough to attract attention. If the alert system is an LED, then it should be located on the face of the unit where you can see it clearly. If the system is audible, then it should be at least 80 decibels so that you can hear it from anywhere in your home. It should also be continuous until you manually turn it off. Some leak detectors use email or an app on your smart device.

These push notifications should be bright and urgent enough to attract your attention. Email should be insistent as well. With the amount of spam that we receive daily, a single notification can be lost in the flood.

3. Smart Home Integration

A great way to take advantage of a leak detector is to integrate it into your smart home. You can use this integration to monitor different detectors or even different properties. By naming the various detectors, you can have your Alexa or Google device tell you in plain English what location is being affected. This can help increase your response time exponentially.

4. Placement

The placement of a leak sensor is important. Some flow sensors are designed to be placed on the water meter, and others are designed to rest directly on the floor. If you place one on the floor, then you should make sure that it can be placed somewhere that it won’t be knocked away or moved easily.

5. Passive or Active Detection

A passive detector is one like a water flow monitor that will simply tell you when something unusual is going on. An active detector is one that you place where a leak might happen and it then notifies you when a leak happens. Deciding which is best for you will depend on multiple factors. For example, if you’re in charge of several buildings, you may want to install several passive detectors at the water line entry to each building. You can combine this with active sensors in vital parts, such as in the basement by the hot water heater. In some higher end active detectors, there is an automatic valve shutoff system that will shut off the water main if a leak is sensed.

For a gas or refrigerant detector, most detectors are passive, in that they will notify you of a leak in the area. It’s up to you to use the detector to narrow down where the leak is happening.

6. Power Source

If you use a battery powered device, look for ones that are rechargeable. If you can’t use a rechargeable integrated battery, then using rechargeable batteries for the detector will likely be your best bet. That means looking for detectors that use batteries that can be recharged, such as AAA, AA, or 9 volt systems.

7. Cost

Many people are concerned about the total initial cost of a system and what the annual costs are. An annual cost can be the cost of batteries or the cost of the electricity to operate it. Additionally, maintenance costs on leak detectors are a thing as well. Gas leak detectors should be calibrated regularly, and if you have a corona or heated diode, those sensors will need replaced.

Primary Causes of Leaks

Best Leak DetectorsWhen it comes to leaks, you might wonder how they come about. After all, shouldn’t a well-designed system have no leaks? Well, certainly, but in some cases, the compounds in the system will naturally create conditions that contribute to leaks. Here are some common causes of leaks according to either water or refrigerants.

  • Refrigerant Leak Causes

The most common cause of freon leakage from an AC or refrigerator is metal erosion. Formic acid or formaldehyde forms naturally as time goes by. This acid eats away at the metal of the AC or refrigerator loop over time. As it gathers in specific places like bends or at valve junctions, these areas are most vulnerable to leaks. Repairing this type of leak can be as simple as replacing the affected area or as complicated as replacing the entire unit. This type of leak is most common with copper coils, which is a major reason why most manufacturers have moved to aluminum for replacement coils.

Another cause of refrigerant leak is a defect in the manufacturing. A valve that is installed slightly cocked can cause problems that don’t appear until 5 or 10 years after initial installation. In these cases, finding the leak and having it diagnosed by a licensed HVAC technician is important.

The final cause of a refrigerant leak is just normal wear and tear. As time goes by, seals and gaskets wear out. There are rubber seals that are located near valve stems that wear out. Rust can form on the exterior and cause breaks in the system. These leaks usually won’t show up until near the end of the useful cycle of the refrigerant unit as long as the system has been taken care of. In this case, it’s usually recommended to have the remaining refrigerant vented and disposed of and the entire unit replaced.

  • Water Leaks

A water leak in your home can show up for a wide number of reasons. Here are a few of the reasons why you may find water on your floor unexpectedly.

o Freezing – When water freezes, it expands. Normally, this is a wonderful phenomenon, but if it happens where the water comes into your home, it’s anything but. A frozen pipe can burst outward, and when the inevitable thaw comes, that’s hundreds of gallons of water waiting to soak your basement and home. These bursts can happen before your primary shut off valve, which means that there’s no way for you to stop it when it happens other than shutting the valve off at the street.

The best way to keep this from happening is to either maintain a flow of water through your pipes or to heat your home to about 40 degrees Fahrenheit at all times. A small flow of water will prevent icing from happening under normal conditions, and keeping your home minimally heated when unoccupied will help keep ice from forming.

o Corrosion – Water and ferrous metals can cause rust, which eats away at pipes and can cause leaks. These are usually small at first, but as the corrosion gets worse, it can grow from a pinhole to a flood. Do yearly inspections of your home’s water lines to check for any discoloring. If you have an older home, it may be worth the expense to upgrade from cast iron or copper to plastic lines rated for potable water.

o Tree Roots – Tree roots love water and they can find their way into the tightest of valve gaps. A tree can infiltrate a water line and as the roots grow, they will split and burst the line. If you notice a wet spot in your yard and a significant drop in water pressure, it might be worth it to do a camera waterline inspection.

While these aren’t the only causes of leaks by far, these are the most common. In any case, if you notice that your water pressure is fluctuating or that your refrigerator or AC are working harder than normal, hiring a plumber or HVAC technician for an inspection may save you thousands of dollars down the road.
