Avoid Water Damage and Keep Your Home Dry with One of These Water Leak Detectors

Home water damage is one of those things you think will never happen to you, until it does. And, should that be the case, you’ll be kicking yourself for not having invested in one of the best water leak detectors.

Water leak detectors are small, easily installed devices with a relatively low price tag, especially when you consider the protection against water damage they offer. Not only can they help detect leaks and floods before they reach the point of no return. They can also help to detect other water-borne problems like mold, even in the very early stages. 

When shopping for your new water leak detector, it’s important to consider these features:

  • Sensor – Whether the sensor is connected directly to the alert device will depend on the make and model of the water leak detector. Some are connected with a physical wire whereas others use WiFi connectivity to transmit information to a dedicated central hub or smartphone. There are also detectors that feature tiny pins for extremely precise readings. These sensors are particularly effective on wooden floors and surfaces.
  • Display – Ensure the information from your water leak detector is communicated in a way well suited to your understanding. If you’re confident using a smartphone then they are a fantastic way to monitor any potential leaks in your home. Smart detectors usually come with their own app to download which can be paired with the supplied sensors. Alternatively, you’ll find a number of more basic detector styles which offer a digital display reading, loud alarm or both.
  • Noise – While advances in technology can offer varying ways to deliver information straight to a smartphone, there are few things more reliable than a loud alarm. It’s best to ensure your alarm has a level of somewhere between 90-130 decibels, similar to a standard smoke detector. 
  • Power – Most water leak detectors are powered by batteries rather than plugging into a socket. This provides greater freedom when choosing where to place them. However, this means it’s important to make semi-regular battery checks.

You don’t need to be a plumber to identify the most leak-prone areas of your home. As a guide, you should prioritize the following areas when deciding where to place your water leak detectors. These include:

At under $13, the Basement Watchdog Water Alarm is a budget-friendly answer to detecting water leaks. It’s capable of sensing as little as 1/32 inches of water, and, when it does, produces an impressively loud 110-decibel alarm. For greater convenience, the water alarm incorporates a six-foot-long wire which allows you to mount the sensor away from the alarm. Additionally, if six feet of wire is insufficient, it’s possible to extend with up to 100 feet of additional wire.
