WATER PROTECTION · BUYING DECISION
Where to place water-leak detectors
Put sensors where a leak is likely to begin, where water will collect first and where an unnoticed escape would cause the most damage.
The short answer
Put sensors where a leak is likely to begin, where water will collect first and where an unnoticed escape would cause the most damage.
Start with the highest-consequence risks
Prioritize the water heater, washing machine, dishwasher, refrigerator supply line, HVAC condensate equipment and the cabinet below each frequently used sink. In a multistory home, give extra weight to fixtures above finished rooms.
Match the sensor format to the space
A point sensor works best where water will reach one predictable low spot. A sensing cable covers a longer edge or perimeter, which can help under appliances or along a utility-room wall. Do not place either where routine splashes will create avoidable alarms.
Test the complete alert path
After placement, use the manufacturer's test procedure to confirm the local alarm, app notification and any linked shutoff automation. Record who receives alerts, label each sensor by location and repeat the check after battery or network changes.
