How to Install a New Garbage Disposal

Thinking about installing a new garbage disposal? If the answer is yes, you have come to the right place because this article will guide you on how to go about. Let’s get started.

Get all the Equipment Needed

See the Things That You Require

When you are going shopping for a new disposal, there are a few things that you need to take into consideration. First of all, you need to know who will be using the disposal and what kind of plumbing you have in place. If you have children at home, it is recommended that you get a batch feed disposal rather than a continuous feed one.

Batch feed disposals are a little expensive and need a stopper before you use them and that is what makes it safe for kids. Continuous disposals get going when you turn the switch on, so if a child sticks a hand inside, it can be extremely dangerous. In addition to this, see the motor that will be right for your house and the kind of features that you want in your garbage disposal.

Tools Needed

Some of the tools needed for the installation are:

  • A disposer wrench
  • A hacksaw
  • A screwdriver
  • Electrical cord
  • Plumber’s putty
  • Safety supplies, including goggles and a dust mask
  • Water pump pliers

Removing the Old Disposal

You need to remove the old disposal before you install the new one. Here is how you need to proceed:

  1. Turn off the power
  2. Detach the dishwasher hose if it is attached to the dishwasher.
  3. Detach the waste line, but make sure that you keep a bucket under to catch any waste.
  4. Take the disposal off by inserting the screwdriver in the ring lung and then by turning it counterclockwise.
  5. Take the rest of the mounting assembly apart and prepare the sink for the new installation.

Installing the New Disposal

Wire the Disposal

Some of the disposals have appliances wired attached but others don’t. If yours doesn’t, you will have to remove the cover plate and attach the wires according to the instructions. After you are done, make sure that you screw the cover back in place.

Install the Drain Flange and Mounting Ring

Roll the putty until you have a long cylinder in hand and then apply it under the sink on the underside of the drain flange. Add the flange in the drain hole, and press it down to attach it and then snap on the fiber gasket, mounting ring, and the backup ring. Use a screwdriver to secure the mounting ring in its place. Make sure that you add putty around the flange for added protection.

Mount the Disposal

Place the disposal and make sure it is facing the drain pipe connection before tightening it back in place.

Connect the Disposal To The P-Trap

Cut the discharge pipe to size and then attach it to the outlet on the disposal. Make sure that you also attach the dishwater discharge tube.

Check the Disposal

Turn the power on and see if the disposal is working or not.
