There are several types of sink drain stoppers, including pull-out, twist-and-pull, and pop-up. Pull-out sink stoppers can be removed by pulling on the stopper until it comes out of the drain. A twist-and-pull design requires lifting then turning the stopper to lock it in an open position and the opposite action (turning, then pressing down) to close it. A pop-up sink stopper works by pushing down the drain cover to open or close the passageway. 

Because plumbing repairs are wide-ranging in scope, job completion time may vary from a few hours or several days. Simple jobs such as clearing a clog, replacing a garbage disposal, or repairing a toilet will only take an hour or two. Large jobs that require digging up yards and checking pipes may take upward of one or two weeks.

To avoid the high costs of plumbing repairs, watch for potential problems. If you see any signs of a leak, consider hiring a professional plumber. A pro can assess the level of damage and make the appropriate repairs.

Plumbing leaks are always better tackled immediately. You can also fix any minor repairs yourself or ask the plumber if they can use less expensive materials.

Once you have your garbage disposal disconnected, you can remove the mounting bracket by unscrewing the bolts that are holding the bracket. You can back them out just enough to pop off the snap ring, which prevents the bottom portion of the bracket from disconnecting from the top when you unscrew the bolts. Use a regular screwdriver to pop off the snap ring, and the rest of the components should fall off by themselves.
