A water detector in the basement will save you a major headache — unless you’re not home to hear it. Leave on vacation for a week, and you could come home to a dead battery in your water detector, thousands of dollars of water damage, and a floating sofa. Like your basic water detector, a backup sump pump sounds a nice little alarm, but it also does something about the problem.
This pump from Wayne will sit quietly, charging a deep-cycle battery, until the power goes out and the water rises. Then the ESP25 system sounds an alarm and begins pumping water at up to 3,300 gallons per hour at zero feet, and over 1,000 GPH at 15 feet. It may not handle a full hurricane, but it should save you from most flooding problems. At $220, it might pay for itself with reduced home insurance premiums alone.
