Flood Buzz
Flood Buzz Small Water Leak Detectors for Homes & Businesses - 6-Pack
Editor's bottom line:
“This water alarm is the best one we tested. In terms of quality, brand and price, we couldn't ask for more.”
Main Highlights
- NO SETUP REQUIRED - PLACE AND PROTECT: The Flood Buzz Small has a factory-installed, pre-tested battery sealed inside - no battery installation, no tools, no app. Open the box, set each unit on the floor near any water connection, and your home is protected from the first drip. Done in seconds.
- UP TO 95 dB ALARM RIGHT AT THE SOURCE: Flood Buzz Small delivers up to 95 dB at the leak location, comparable to an alarm clock. Best results come from placing it close to the water source inside an enclosed cabinet or under a sink. For whole-floor coverage, place two units together or upgrade to Flood Buzz Pro at 110 dB.
- FACTORY-SEALED BATTERY - UP TO 3 YEARS ACTIVE LIFE: The internal 12V battery is sealed at the factory and is not user-replaceable. This is a design feature: no battery compartment means no accidental installation errors. Each unit has a replace-by date stamped on the housing - your built-in reminder to swap in a fresh unit when protection is due for renewal.
- ALERTS AT THE FIRST DRIP - BEFORE WATER SPREADS: The moment water contacts the two metal prongs on the base, Flood Buzz sounds the alarm. Place prongs flat on the floor in the most likely path of a leak - directly behind a toilet, under a supply line, or at the low point of a drain pan - for fastest response to even a slow drip.
- PROTECT AGAINST $5,000+ IN WATER DAMAGE FOR UNDER $8 A SENSOR: A supply-line failure under a kitchen sink can lead to $5,000 or more in repairs, flooring replacement, and water damage restoration. This 6-pack covers three high-risk locations in your home, business, or RV for roughly $9 per sensor - protection that pays for itself at the first catch.
- COMPACT ENOUGH TO FIT WHERE WATER HIDES: At 1.75 x 1.5 x 1.5 inches, Flood Buzz Small fits behind toilet bases, beneath dishwasher kick plates, inside cabinet corners, and in HVAC drain pan channels where standard water alarm sensors cannot reach. After any leak event, wipe the prongs dry and the unit is ready to use again until the replace-by date.
- PATENTED DESIGN FROM A FAMILY-OWNED AMERICAN BRAND: Flood Buzz is a patented water leak alarm made by Archetype Ltd., a family-owned company based in New Jersey. Reviewers consistently describe the unit as well-made and solid for the price. The single-piece sealed housing needs no assembly and is reusable after every leak event - wipe the prongs dry, good until the replace-by date.
