Where Water Strikes First

Six Places Every Home Should Watch

UPSTAIRS BATH LAUNDRY ROOM KITCHEN & SINK HVAC & UTILITY WATER HEATER SUMP PIT DRAIN PAN 1 2 3 4 5 6
1

Water Heater

Tank failures flood fast and cause major baseline damage.

2

Washing Machine

55% of washer claims are caused by burst high-pressure hoses.

3

Kitchen Sink & Dishwasher

Slow hidden drips quietly rot cabinets and subflooring.

4

Upstairs Bath

Overflows soak through floors and ruin ceiling drywall below.

5

Sump Pit

Pumps fail most during heavy storms when you need them most.

6

HVAC Drain Pan

Condensate drain lines clog quietly and back up unexpectedly.

Most homes have six or more leak zones. Since each standalone alarm protects one dedicated location, we recommend covering the areas with the highest repair costs first: the water heater, washer, and kitchen sink.

Saved my basement from a $5,000 disaster.
I placed one by my water heater and another near the sump pump. Last week, a small valve leak started while we were asleep. The 90dB siren woke me up immediately before water could even reach the drywall. Simple, loud, and worth every single penny.

Zero app hassle. Just drop and protect.
I hate smart devices that require a hub, Wi-Fi passwords, and endless app notifications. These Blanco sensors are pure peace of mind: you pop in the battery, put it under the sink, and it just works. Bought the 3-pack for my kitchen and bathrooms!

Covered all 5 leak zones in our house
After reading about how expensive water damage repairs can be, we bought the multi-pack to cover our water heater, dishwasher, washer, and upstairs baths. Best investment we’ve made for home maintenance

Extremely loud alarm – exactly what you need.
Tested it with a wet paper towel first to see how sensitive it is. It sounded the alarm instantly! You can easily hear it through closed doors and from the upstairs bedroom. Put one under the washing machine hose right away.
