First unplug your current garbage disposal, then assess what tools you’ll need to remove the pipes.

Plastic slip nuts can be turned by hand, but steel requires a pair of slip joint pliers.

A plastic tub to catch water and a few rags are also useful.

Next, begin disconnecting the plumbing lines from the disposal.

Then using a screwdriver you could remove the old mounting bracket and attach the new one.
