Every now and then a garbage disposal will need to be replaced. It doesn't happen very often, but occasionally a solid object will get wedged inside the disposal's mechanisms and cause it to break. There are a few key factors in choosing the right garbage disposal replacement. Stainless steel parts mean no corrosion, and the disposal should have no less than a 1/2 horsepower motor. Whirlaway garbage disposals are one of the more popular brands. They come with stainless steel parts and have finely tuned motors. If you have a broken Whirlaway garbage disposal, read the following steps on how to remove it in order to install a replacement.
Twist off the lock-nut on the top of the disposal and the bottom of the drain pipe.
Wiggle the drain pipe so it loosens from inside the garbage disposal.
Insert a screwdriver into one of the metal flanges on the top of the disposal. Slowly unscrew the top clockwise. Because it is only a rubber gasket, be careful not to tear it by unscrewing it too fast. Once it is loosened, finish untightening the unit with your hand.
Pop off the Whirlaway garbage disposal from underneath the sink.
Disconnect the dishwasher drain line at the garbage disposal. If there isn't a dishwasher, then no line needs to disconnected.
Unbolt the electrical outlet from the bottom of the Whirlaway garbage disposal. Use a wrench to unscrew the nut.
