Whole-Home Water Leak Alarm Kit – Flood Buzz® Small (6 & 12 Packs)

The calls we hate most start with "I didn't know it was leaking." A slow drip under a sink, behind a toilet or under the dishwasher can rot a cabinet or subfloor before you ever see it. This kit puts a small, loud leak alarm at every one of those spots for less than the cost of one service call.

Where to put them: under the kitchen and bathroom sinks, behind each toilet, under the dishwasher and fridge water line, next to the washing machine, and by the sump pump.

Why it's worth it:

• Compact — 1-1/2" tall, 1-3/4" deep — fits in tight cabinets
• Up to 95 dB alarm the moment water touches the prongs
• Battery pre-installed and lasts several years
• No moving parts, no wiring, no app, no Wi-Fi to set up
• Reusable: wipe the prongs dry and set it back down

How to use: unwrap and place it where a leak would show up first. Test by touching the two prongs with a damp cloth. Replace by the "Replace by" date on the unit.
