Things You'll Need
The Badger 1 is a under-the-sink garbage disposal manufactured by the InSinkErator company. The device is operated via a wall switch that activates a motorized wheel and grinds up food into small particles. The particles are then flushed down the waste water line. Over time, a Badger 1 can begin to leak, which is usually the result of a faulty or disintegrating seal inside the top of the device.
Stop Leaks at Hose Connections
Move your hands over the surface of the Badger 1 to identify the location of the leak. Feel around the waste tube at the bottom of the unit and at the dishwasher connection tube on the side of the Badger 1. Not all Badgers are connected to a dishwasher.
Disconnect the leaky tube. To disconnect the waste tube, remove the two screws on the faceplate. To disconnect the dishwasher tube, loosen the screw in the metal ring fastener and pull the fastener off the end of the tube.
Wrap the leaking tube connection location on the Badger 1 with plumber's tape, then reconnect the tubes to the disposal.
Test for leaks by running the water in the sink and turning on the Badger 1.
Replace a Faulty Seal
Turn off the power supply to the Badger 1 at the main fuse box for the house.
Locate the electrical connections on the bottom of the device and use a screwdriver to loosen the screws holding them in place.
Locate the tube that connects to the Badger from the dishwasher, if applicable. Remove the metal clip that holds the tube onto the Badger by loosening the screw on the clip. Pull the hose away from the unit.
Locate the waste tube on the bottom of the Badger 1 and use a screwdriver to remove the two screws in the face plate. Pull the waste tube off of the device.
Grasp the sides of the Badger 1 with both hands and turn it counterclockwise, using firm pressure to unscrew it from the top mounting brackets.
Remove the screws located at the sides of the Badger 1 approximately 6 inches from the bottom. Pull the plastic cover off of the bottom of the unit.
Look inside the disposal unit to locate the seal, which looks like a thick, round, rubber circle. Pull the seal out and take it to a hardware store to purchase a replacement.
Insert the new seal into the unit in the same position as the old seal. Reinstall the Badger 1 by reversing the steps taken to uninstall it.
