How To Remove A Garbage Disposal
Sometimes customers like me to remove and do away with their old garbage disposer.
There are various reasons to remove a garbage disposal from your kitchen sink permanently. Problems with old drain lines are perhaps the most common reason to remove a garbage disposal and use a basket strainer instead.
With old drain lines, even small pieces of food can build up in the pipes and cause kitchen stoppages. If you are good at remembering to throw away kitchen scraps and you are tired of frequent kitchen sink stoppages, you may choose to remove your garbage disposal.

Disconnect the Garbage Disposal
To remove a garbage disposal begin by unplugging and disconnecting the disposal. First, unplug the garbage disposal from the wall.
Next, you will have to remove the drain trap which connects the garbage disposal to the drain pipe. Place a container under the trap so you can catch any water that drains from the pipes.
Using pliers remove the two trap nuts and pull the trap pipe straight down. Remove the continuous waste by removing the nuts with pliers and pulling the pipe out.Continue to 3 of 8 below.

Remove the Garbage Disposal
Insert a flat screwdriver into the lower mounting ring and turn it 1/4 turn counterclockwise to unlock it. The disposal will come straight down so be ready to catch it.
What is left is the mounting assembly. To remove it loosen the three screws first, then use a flat screwdriver to pop the snap ring out of position. The rest of the mounting assembly will come off easily, and you can pull the top piece out from the top side of the sink.

Install the Basket Strainer
There are many types of basket strainers to choose from. Each basket strainer will have installation instructions so follow the directions of your strainers.
Make sure to put a ring of putty around the sink strainer before inserting it into the sink opening. Put the rubber washer first then the bottom mounting cup before the mounting nut. Tighten the mounting nut until it is firm. Remove the excess putty from the top of the sink.Continue to 6 of 8 below.

Attach the Drain Pipe and the Dishwasher
The basket strainer is connected to the drain with a flanged tailpiece. If you have a dishwasher, you will need to use a flanged branch tailpiece which has an additional inlet for the dishwasher drain line.
The flanged tailpiece screws directly onto the basket strainer. Make sure to use the tailpiece washer that should have come with the basket strainer. Also, it is recommended that you put a pinch of putty on the nut between the tailpiece washer and basket strainer.
Re-install the dishwasher tube onto the branch tailpiece using pliers.Continue to 7 of 8 below.

Install the Continuous Waste
Install the continuous waste pipe. The pipe will likely need to be cut to size. To get the measurement put one end of the pipe in place and make a mark where the cut needs to be made.
The continuous waste pipe should have a mid downward slope from the trap to the drain. Keep that in mind when you measure and cut the pipe.
Once your continuous waste fits right, you must tighten both nuts making sure the slip joint washers are on facing the right direction. The washers should be tapered down toward the threads.Continue to 8 of 8 below.

Install the Trap
Finally, install the trap and trap arm. You may have to lengthen the pipe with an extension tailpiece to get it to line up correctly.
Cut your pipe to suit and tight all the nuts making sure the slip joint washers are on facing the right direction. The only part you do not need a slip joint washer is where the trap and trap arm come together.
Tighten all the nuts by hand and check both sides of the sink for leaks by filling the sinks up and draining them. If one nut leaks, then tighten it just a little extra with pliers.
