Are Water Sensor Systems Right For You?

Common water damage from plumbing systems cost homeowners, renters, and landlords billions of dollars every year. Plumbing problems such as leaking or damaged tubs, sinks, and showers, leaky rods, washing machines, water heaters, and frozen pipes result in thousands of water damage insurance claims annually.

No matter how prepared you are for flooding or water damage, you can’t be everywhere water might make an unannounced, uninvited appearance. This is one reason many people have invested in water sensor systems.

What Is A Water Sensor System?

A water sensor system is built to alert a homeowner of potential water damage before it gets out of hand. They are typically placed on the floor where leaks are likely to occur and detect water.

Types Of Water Sensor Systems

There are a few different types of water sensor systems including:

  • Automatic shut-off systems – The key word here is “automatic”. When a sensor is set and detects water, is wirelessly instructs a shut-off valve mounted on your water main to shut off water supply. The system promises 24/7 vigilance, even when you’re not at home. Because automatic shut-off systems require no human interaction and shut off water right after detecting a leak, they are potentially the most efficient way to prevent the most water damage.


Before you go out and purchase one of theses systems, there are a few things you should keep in mind:

  • Automatic shut-off systems cost around $1,000
  • You will need enough sensors to cover all leak-prone areas
  • Any water the sensor detects may trigger a shutdown, regardless if the water is from an emergency leak or a small amount of water that landed on the sensor.
  • Remote Alarm Systems – Remote Alarm Systems typically use more sensors to detect not only water but temperature fluctuations and power outages. Once the system detects any of these things, it automatically dials your phone number to report the problem.


Things you should consider before purchasing this type of system include:

  • Does not completely shut down water supply.
  • There’s no guarantee it will detect every little water leak.
  • It is hundreds of dollars less than automatic systems.
  • Local Alarm Systems – Local Alarm systems are the simplest, low-cost options for preventing water damage. They often integrate into other home monitoring devices. These do not require professional installation, you manually put the sensors near leak-prone areas.


Things you should consider before purchasing local alarm systems:

  • Typically under $50
  • May not catch every water leak, so you may still end up paying for costly water damage.
  • You won’t hear a local alarm if you’re not at home.
  • They may not be as sensitive to water detection as the more sophisticated systems.

Water sensor systems are not guaranteed to detect all water leaks within your home. Even the most robust and well-planned water system is not foolproof. To be on the safe side, it’s best to purchase property insurance that will help you cover water damage costs if by chance, your water sensor system fails to do its job.
