Installing a new garbage disposal is a simple DIY (Do-It-Yourself) task and this article describes how you can do it.

Garbage disposal is a kitchen appliance used for disposing of garbage. It runs on electricity and is attached to the drain of the kitchen sink. It is used for the left-over remains from a meal or other waste down the sink.

Step 1: Buy a New Garbage Disposal System

While buying a new garbage disposal system, you need to be aware of the different horsepower ratings for this system. The general horsepower ratings are 1/3 HP (light duty), ½ HP (medium duty) and 1.0 HP (heavy duty). You should also check the different brands and prices that are available in the market. Decide on one that meets your budget. You will need to know the dimensions of your kitchen sink so that new garbage disposal system will fit under it.

Step 2: Assemble Tools

Get all the tools that you need and have them within reach. If possible, remove the cabinet doors under the sink. It will make your job easier.

Step 3: Clean

Disconnect the waste assembly and remove it from the sink flange. Make sure that a mess is not created by putting a bucket on the floor to collect the waste that may come out. Clean the area out with old rags.

Step 4: Flange

Install a new flange over the sink hole. Apply plumber’s putty on the flange. Remove the entire mounting assembly from the garbage disposal. While holding the flange in place, attach the sink flange to the upper mount assembly. Follow the instructions and put the gasket in place. Slide the mount ring over the flange. Tighten the screws. Do not use unnecessary pressure as this can cause damage. It must be tight enough so that the assembly is secure in its place.

Step 5: Attach Disposal to Sink

Adjust the disposal so that the drain tube is lined up with the drainpipes. Any waste on the P-Trap should be cleaned off. If the dishwasher also needs to be connected, then take out the drain plug from it and connect to the dishwashers drain hose to the drain pipe. Then place the disposal system underneath the mount assembly. The mount tabs must glide over the mount tracks. Place the top of the disposal into the lower mount ring. Tighten the rings with a screwdriver.

Step 6: Connect Drainage Tube

Using a wrench, ensure that the drainage tube is aligned with the drain trap.

Step 7: Power Connections

Ensure that a 120 volt, 20 amp circuit breaker is placed under the sink. A wall switch will also be required next to the sink. A power cord will need to be connected to the disposal system.

Step 8: Reassemble and Test

Ensure that all the connections are completed as required. Run the water to test for leaks. Reconnect the power supply by plugging in the power plug. Put some garbage in the disposal unit to confirm that it is working correctly.

While installing a garbage disposal system can be a messy process, the benefits far outlast the problems faced during this process.
