|The Portable Water Alarm is an early warning system for your home to help prevent water damage and mold from leaking pipes and appliances. The alarm sounds with a 100dB volume, assuring you are alerted in time. No installation is needed. Simply place the sensor on a dry surface in the bathroom, basement, laundry room, under the sink, attic, or garage. When the battery runs low, the alarm will let you know.|
Works As Advertised8/22/2013
Ordered four. Installing 9-volt batteries took some finesse, as wires can make pushing battery into compartment tricky--once in the cover closes just fine. Tested all on wet paper towel, and they worked as advertised. Loud. Have yet to hear "low battery" chirping. Supply hoses to clothes washers, toilets, and sinks can blow at any time. Being alerted as soon as they do might save you hundreds or thousands of dollars. These alarms are well worth the price.
