Frequently Asked Questions

Where is the best place to put the Vivint Water Sensor?

We have reviewed water loss claims data to help prioritize where water sensors should be placed to avoid the costliest home damage.

  • Near the sump pump if you have a basement
  • Behind the washing machine
  • Under the hot water heater
  • Behind the toilet
  • Under the kitchen sink
  • Behind the dishwasher
  • Behind the refrigerator
  • Under bathroom sinks
  • Under/near the AC condenser

While these are some of the most common sources of standing water and leaks, it’s not an exhaustive list — water damage can occur throughout your home from multiple sources. A Vivint professional will help you determine the best locations for water sensors in your home.

Are water leak detectors worth it?

Yes! Because water damage from appliances and weather incidents is common and expensive for homeowners, water sensors are a must-have. They detect water in your home where it shouldn’t be and send immediate alerts, giving you time to stop leaks before they cause serious damage. Learn more about how water sensors work.

How big is the Vivint Water Sensor?

The Vivint Water Sensor measures 2.5” h x 2.5” w x 1” d.
