Water free falls through the debris filter diverting leaves and twigs. Water then flows underground through 8 feet of PVC pipe to the bubbler pot. As water fills up in the bubbler pot the lid raises up to let water evenly overflow onto your lawn.


The UnderGround Downspout works well with either downspout or sump pump discharge. Keeps ice from backing up and burning out the pump. Offering the UnderGround Downspout system with your program will give your salesmen an edge over the competition!
