Why Should You Install a Water Leak Detector?
Water leak detectors are crucial to preventing water damage that could cost you thousands, or even tens of thousands, of dollars. But there are other reasons as well. Here are the main benefits of having a water leak detector.
Avoid Expensive Repairs
So this benefit was already mentioned, but it doesn’t hurt to say it again. Water damage is expensive and common, so why not do everything you can to prevent it? Even if you don’t get a water leak detector that will shut off when there is only a slight hint of water, you could still prevent excessive damage by shutting off the water before the water builds up.
Avoid Costly Water Bills
A leak isn’t always bad enough to cause water damage or even to be noticed. But a slow leak will still impact your water usage and attack your wallet. A water leak detector can help you detect leaks both big and small so you can avoid using too much water.
Water can be a significant safety hazard. If it gets bad it can cause structural damage. It can also be conducive to mildew and mold that can cause a plethora of health problems. But the primary safety concern is electricity. If water flows around appliances and outlets, it can harm you and your home.
Whether you are sitting at home or driving a thousand miles away, your water leak detector can alert you of a leak. This can help you prevent flooding and other water related problems.
How Does a Water Leak Detector Work?
There are different types of water leak detectors. Some use sensors, some measure water flow, and still others use ultrasonic waves. It is important that you weigh the pros and cons of each type and know how they work.
The first type of water leak detector uses a mechanical turbine to measure the amount of water that is flowing through your pipes. When there is a significant deviation from the normal water flow, a signal will be sent so that it closes the valve. Usually this type will be installed at the water’s entry point into the home. This ensures that the water will be cut off no matter where the leak is.
This type of water leak detector will send ultrasonic waves up and down your pipes. This will record the flow rate and give it to the system. Then, this information is sent to your Wi-Fi router and smartphone. The ultrasonic waves detect higher water flow and will close a ball valve. This stops water to the home.
A sensor based water leak detector typically consists of two parts, the transmitter and the sensor. The sensor is the part that detects water, and it may be a good idea to place multiple sensors around your home. The sensor alerts the transmitter as soon as it detects water. The transmitter will then sound the alarm.
Sensors should be placed in any location where a potential water leak can occur. The more sensors, the more protection you have against water leaks. Places where water leaks are common include:
- Around Dishwashers and Refrigerators
- In the laundry room
- In bathrooms (especially around the toilet)
- Around the water heater
- Under sinks
What to Look for in a Water Leak Detector
Different models of water leak detectors have different features that you should be aware of depending on your specific needs.
Different detectors sound the alarm with different amounts of water. Some will alert you as soon as a single drop hits the sensor, while others take more. Some models even have adjustable sensitivity so that you can configure it to suit your specific home.
This feature can be extremely beneficial, especially if a leak occurs while you are away from home. It works by closing a valve on your waterline as soon as the sensor detects moisture. It will also send you an alert or sound an alarm, but takes the stress away from worrying about turning off the water supply yourself. This feature usually costs additional money, but it can save you on expensive repairs in the future. The cost may also be worth your peace of mind.
Most water leak detectors only use a battery so that the sensors will alert you of a leak even during a power outage. However, some also need to be connected to your water supply to access some features, specifically automatic shut-off.
Battery life is important to consider. Some last up to 10 years while others may only last three. It is also good to make sure a water leak detector has a low battery warning. You never want it to run out of batteries without you knowing.
Not all water leak detectors will send you an alert on your smartphone, but a lot of them do. This is a feature that you should look for. If you aren’t home and your detector doesn’t have this capability, then what good if the water leak detector in the first place?
This feature is especially important for those who live in very cold climates. It can alert you of freezing pipes so that you can avoid a burst. Some models will even let you know before the pipe freezes so that you can take the necessary precautions.
