The size of the motor in the garbage disposal directly correlates to the units grinding ability. Garbage disposals typically have between 1/3-1 horsepower motors. Choose the correct horsepower based on the waste that you need to remove. 1/3 horsepower units will help tackle tasks like grinding vegetables easily, but more power is recommended if disposing a large quantity of food waste such as, vegetables and harder to grind meats.
The easiest way to apply that force is to squeeze them together using tongue-and-groove pliers, such as Channellocks. You’ll need medium or large pliers to do this. Unlike prying on the lower ring with a screwdriver or hex wrench-the method recommended in most instruction sheets-squeezing can’t disturb the position of the sink flange and cause it to leak. Plus, it’s easier on the wrists.
Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
