Review on Battery Outdoor Alarm Back Up Sump by Ognjen Cao

This is a top-notch sump backup alarm that has kept my basement free of water damage .As a result of my tests I determined that it can last for 12 hours without power. The setup is straightforward and the alarm sounds when it detects water. The only downside is that it doesn't come with batteries, but that's a minor issue. Overall, this backup alarm is dependable and gives me peace of mind during heavy rains..
