Water Heater Leak Alarm – Flood Buzz® Blue (1, 2 & 4 Packs)

Most water heaters don't fail all at once. They drip into the pan for weeks before anyone notices, and by then the floor, drywall or finished basement is soaked. The Flood Buzz® Blue sits in your water heater's drain pan and sounds the moment water touches it, so you catch a small leak while it's still a cheap fix.

Why it's worth it:

• Up to 110 dB alarm — loud enough to hear from upstairs
• Slim design (4" tall, 5/8" deep, 1-3/4" wide) made to stand in a water heater pan
• Prongs sit 1/16" off the ground to catch the first water
• Battery pre-installed and lasts several years — nothing to wire, plug in or set up
• Reusable: wipe the prongs dry and set it back down

How to use: unwrap it and place it in the pan. Test any time by touching the two prongs with a damp cloth. Replace by the "Replace by" date printed on the unit.
