- 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.

- PROTECT AGAINST $5,000+ IN WATER DAMAGE FOR UNDER $10 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 3-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.
- COST-EFFECTIVE PROTECTION NOW OR THOUSANDS LATER: A small water leak can cause $5,000 or more in damages. Each Flood Buzz Pro delivers up to 3 years of always-on protection with no battery to buy or replace - sealed and ready from the moment you place it. The easiest insurance you will ever buy.
- HOME, BASEMENT, ATTIC WATER ALARM: Place a Flood Buzz Pro in any basement utility area, or anywhere indoor flooding starts. The 110 dB alarm triggers instantly when water reaches the contact prongs - no app, no hub required. Catch leaks before damage spreads.
- 110 dB ALARM: Flood Buzz Pro sounds at 110 dB the moment water contacts the sensor prongs - as loud as a car horn. Loud enough to carry across adjacent rooms and through most single-story spaces. For multi-story homes, place one unit per floor near high-risk appliances to stay in earshot wherever a leak starts.
- PLACE IT ANYWHERE WATER CAN REACH: Under kitchen and bathroom sinks, behind toilets, next to water heaters, in basements and attics, beside dishwashers, washing machines, and inside RVs. The compact 2x2x3-inch sealed body fits tight spots most alarms miss. Wherever pipes or appliances can fail, a Flood Buzz Pro belongs.
- UP TO 3-YEAR BATTERY WITH REPLACE-BY DATE ON THE UNIT: The factory-sealed battery is already installed and ready. The replace-by date is stamped directly on each unit - no guessing, no maintenance schedule to track. Sealed design means no battery-lid frustration and no dead-battery risk between routine checks.
- 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.

- UNDER $20 TO PROTECT AGAINST ONE OF THE COSTLIEST HOME LEAKS: Water heater failures are among the most common causes of residential water damage. Early detection gives you time to replace the heater before water reaches flooring or adjacent walls. Flood Buzz Blue owners report catching failures early enough to avoid major repair bills - small alarm, large save.
- LOUD ENOUGH TO HEAR FROM UPSTAIRS: Up to 110 dB alarm triggers the instant water contacts the two-prong sensor. One small alarm placed in your water heater drain pan alerts the whole household the moment a leak starts, day or night.
- BATTERY STAYS LIVE UNTIL THE DATE STAMPED ON THE UNIT: The battery is factory-installed and sealed at the factory - no batteries to buy, insert, or check. Every unit arrives with a replace-by date stamped on the housing, typically 2 or more years from when you receive it. The alarm stays ready until that date.
- CONTACT SENSOR WITH NO MOVING PARTS: Two metal prongs on the base detect water the instant it bridges the circuit. No calibration, no adjustable sensitivity, nothing mechanical to fail. The sealed battery compartment protects the electronics from moisture, keeping the alarm ready for multi-year, always-on monitoring.
- NO WIRES, NO APP, NO INSTALLATION: The factory-installed 12V battery means the unit is ready the moment you open the box. Place it flat in your water heater drain pan and monitoring begins immediately. No tools, no connectivity, no programming. Set it and forget it.
