Smartphone app notifies homeowner of water infiltration

One small leak at your house can result in big difficulties and thousands in damage. You must protect against this danger; luckily, there’s a simple way to accomplish this. A water sensor is a simple, effective, and economical solution. See how they work and why you should integrate water sensors into your Lexington smart home.

How water sensors shield Lexington homes

Water infiltrates homes in many ways, whether from a broken appliance, plumbing failure, storm-related incident, or human error. No matter how it takes place, you must know at once, and this is why water sensors are important. But how do they really work? 

Most water sensors are conductive and function with corresponding electrodes. When water reaches the electrodes, an electrical circuit is created, triggering your alarm. You’ll also come across capacitive sensors that emit an electrical field. Your alarm sounds when water reaches the conductive surfaces of these components and interrupts the field. Optical sensors utilizing infrared LED light are another option.

Certain innovative water sensors offer even more defense as they have built-in temperature sensors. This is an exceptional benefit in preventing pipe freezing. If there’s a drastic decrease in temperature, you’ll know immediately. Taking steps before pipes break will protect you from water infiltration and costly repairs.

Why integrate water sensors into your Lexington smart home? 

When water issues occur, you have to be alerted immediately. You can reach this aim by incorporating water sensors into your smart home. Whether you’re home to hear the alarm or somewhere else, you’ll be sent an immediate notification on your smartphone. As an added benefit, your round-the-clock monitoring specialists will be informed. Every moment is critical in a water emergency to limit the damage and interruption to your household.

Where should you install water sensors?

Any area at risk of water infiltration is an ideal place for water sensors. Put them in these spots:

  • Bathrooms: Place behind toilets or near bathtubs.
  • Basements: Water commonly infiltrates lower floors through cracked walls or because of excess rain or malfunctioning sump pumps.
  • Around water heaters or appliances: Any water-utilizing appliance could leak in time.
  • Below sinks: Water sensors are ideal for discovering plumbing leaks in locations hidden from view.
  • Attics: Identify roof leaks early and prevent expensive repairs.
