Description of Flood Detective Water Leak Sensor and Alarm

Stop flood damage and toxic mold before it starts! The Flood Detective is the economical and reliable solution to detect water leaks before they can cause significant damage and costs in the home or office. Once detecting as little as 1/32" of water, the Flood Detective will sound a 92 dB alarm which can be heard over common household noise. The remote sensor can be placed as far as 8 feet away from the alarm device. The Flood Detective conveniently uses either A/C, battery or A/C with battery backup. Simply put, the flood detection can be placed almost anywhere in the home or office including in and around basements, dishwashers, toilets, washing machines and hot water heaters. Its solid state circuitry and fail-safe technology informing of A/C power loss or low battery levels ensures reliability and confidence. The Flood Detective is an easy to install and operate device that is a must for those concerned about water damage and mold growth.

Flood Detective Water Leak Sensor and Alarm are ideal for someone who...
  • Wants a reliable audible alarm alerting you at the first sign of a potential water issue.
  • Would like a flood detector that can be powered either using a battery, A/C adapter or combination of A/C with battery backup.
  • Wants a flood sensor and alarm device that is easy to install virtually anywhere in the home or office.

Features of Flood Detective Water Leak Sensor and Alarm

  • Detects as little as 1/32" (.8mm) of water and will sound an alarm for sufficient time to alert you to a problem (will sound for 10 days with a fresh battery)
  • Features an alarm siren loud enough to be heard over common household noise: certified at 92 dB by an independent professional testing laboratory
  • Remote Sensor can be placed as far as 8 feet away from alarm. Sensor is wafer thin for use under carpets or small spaces and has an adhesive strip so it can be fixed firmly in place.
  • Can be used almost anywhere: uses either A/C, battery (not included) or A/C with battery backup
  • Easy to install and includes a wall mount bracket
  • Incorporates an accessory output which can connect to a master alarm system or other control devices, such as signal devices for the hearing impaired or remove sirens for detached buildings
  • Fail-safe technology informs you of A/C power loss or low battery levels
  • Will protect multiple risk areas: uses patent pending technology to allow the user to connect multiple sensors to one alarm unit, permitting low-cost yet effective protection of adjoining high-risk areas. Each optional sensor is equipped with 8 ft. of flexible, low-impedance corrosion-resistant wire with a two-prong jack on one end. The sensor itself has a corresponding two-prong receptacle that mates to the jack. This unique design in sensor topography allows multiple sensors to be daisy-chained to a single alarm unit, offering unrivalled flexibility in sensor placement and flood warning coverage. In theory, there is no limit to the number of sensors that can be daisy-chained to a Flood Detective alarm unit. However, it is recommended that you connect no more than five sensors per alarm to help determine which sensor has been activated in the event of an alarm condition.

  • Parts of the home you could protect with the water leak detector alarm:
    • Lowest part of your home and basement: Even if you don't have a water leak detector everywhere in your home, water will always collect at the lowest point.
    • Under the bathroom sink: leaks in cabinets underneath sinks are a common source of water damage. Cabinets are expensive to replace.
    • Behind a leaky toilet: A leaky or overflowing toilet can cause significant floor, wall, and cabinetry damage.
    • By the water heater: You can detect water at the first sign of leakage and prevent your water heater bursting.
    • Under a dishwasher: Water leaking out of a dishwasher is hard to detect before it ruins your floors and nearby cabinets.
    • Under the refrigerator: Like the dishwasher, water leaks out of refrigerators in hardly noticeable amounts until it's too late.
    • Under the washing machine: One of the most likely to leak home appliances. Let our alarm let you know when your washing machine has a leak.
    • Under the kitchen sink: Leaky pipes under a kitchen sink can cause just as much — and just as expensive — damage as bathroom sinks.
    • In the attic: How often do you go in your attic. If your roof was leaking it could do major damage before you noticed it.
    • Other areas including: indoor and outdoor hot tubs, irrigation systems, guest bathrooms, sump pump overflow, in skylights and by windows, beneath aquariums

It's always essential to know of a water leak before potential water damage occurs. Lack of early detection of water leaks can reduce the chances of collecting from an insurance company since insurance claims are frequently denied if the cause of the damage has existed for more than 24 hours. The Flood Detective water detector alarm is a no-risk, affordable device that is a must for any home or office. We found that it takes just seconds to install and can be placed virtually anywhere! Some examples of placement include in basements that tend to frequently flood, water heater rooms, laundry rooms, around toilets and other plumbing areas and near pipes that could potentially burst during winter months. It's a versatile device which can be powered by an A/C or by a 9 volt battery in case there is no power source nearby. For added security, one can power the device using both the A/C with battery backup in case there is a power outage or the power source is damaged. When we put it to the test we found that the sound level of the alarm was loud enough to be heard throughout the entire office and could also easily be heard throughout common household noise and multiple floors. Flooding incidents and much time and money spent on repairs can quickly be averted by placing this simple device in the home or office. The Flood Detective is thoughtfully and thoroughly designed to keep your mind at ease.
