Buying A Garbage Disposal

What To Look For In A New Garbage Disposal 

Garbage disposals can range anywhere from $50 to $300 dollars. Even the cheapest of these disposals will hold up fairly well under normal conditions. With that being said, why would you want to invest in a more expensive disposal? Buying a more expensive disposal will guarantee you longevity, more power, less mechanical problems, and a longer warranty.

With a little research you will find that the more expensive units utilize stainless steel grinding blades, and bigger motors. Both of these factors will ensure that your disposal will be able to grind the larger food items into a pulpy consistency. Now, that you know a little bit about shopping for disposal, it’s time to learn how to change out that old disposal.

Removing The Broken Garbage Disposal

You want to start by shutting off the power to the unit. Once you have done that it will be time to remove the electrical panel, but pay close attention to how the wires are connected. Write it down, if you have to, but in most cases the two white wires will be connect together, as well as the two black wires, and the ground wire will be connected to a ground screw.

You need to remove the  clamp on the dishwasher hose and then pull it free. You will now have to remove all the drain PVC connections. The disposal should now just be connected to the sink drain fitting, but it may be connected in several different ways. It could be connected with threaded plastic nuts, large hose clamps, or a mounting ring assembly. A mounting ring assembly is the most common type of connection and that is probably how your disposal is connected. To remove the disposal, you need to support it at the bottom with one hand and  rotate the it counterclockwise with the other.

The disposal should now slide out and you will be able to remove the rest of the sink drain assembly. Be sure to remove all the old plumber’s putty, so that the new connection will make a clean seal.

Installing A New Garbage Disposal 

To install your new unit you will have to begin with the sink drain assembly. Roll some plumber’s putty around the sink drain fitting and press it firmly into the sinkhole. Now, from underneath the sink, you will have to attach the washer and the nut. Firmly tighten everything into place and you will be ready to install the mounting flange and retaining ring. Simply just snap the retaining ring on the drain spout and tighten the bolts, until everything feels snug. You will notice that the plumber’s putty will squeeze out, which is a good sign.

Making The Electrical Connection

It is always easier to go ahead and connect the electrical wires, before you put the disposal in place. The wiring should be long enough and if it isn’t you might have to add on. Simply just remove the electrical panel on the new disposal, connect the wires in the appropriate manner, and reinstall the cover.

All new disposals will come with a dishwasher discharge nipple, which will be plugged and if you intend to use this connection, you are going to have to remove the plug first. You can just push the plug, using a screwdriver. You now want to lift the disposer in place and rotate it clockwise until it bottoms out.

Making The Plumbing Connections

You now want to reconnect the dishwasher and plumbing pipes in the same manner that you removed them. It is possible that you may have to make some alterations to the drainpipes, but this should not take very long.


Now, you are ready to utilize your new garbage disposal. Always make sure to turn on the spigot, before turning on the garbage disposal, because you do not want to risk damaging the motor.
