Install the New Pump Above the Sump, Run Water and Drain Lines
A battery-powered pump is a great backup for your main sump pump, especially if your house is supplied by a well. But if you’re on a municipal water system, a water-powered backup pump may be a better option (a well pump won’t work if the power’s out). The price you’ll pay for water consumption during a power outage is a pittance compared with the cost of a flooded basement. And, a water-powered pump never needs new batteries.
The pump shown here (Basepump RB750, from basepump.com ) installs on the ceiling above the sump. You’ll have to run a 3/4-inch water line to it and connect the remote float and tubing to the switch near the pump. Then run a separate self-draining pipe that drains outside.
