Some steps for replacing garbage disposal

If you already own a garbage disposal that is too loud for you or not meeting you needs, then you need to replace your old one with a new one. Replacing garbage disposal is not a rocket science it’s pretty easy. You just need to follow some steps. And I’m going to talk about the steps for you.

1. Do some study on your new disposal? Try to figure out the parts and other things. Read the manual book and description. It’ll help you to do your work faster. If you, at least, know something about the disposal and how the parts work you can easily install the new one. Also, make sure you have all parts ready that listed on the instruction sheet.   

2. To install the new one, you have to remove the current one very gently. First and most importantly power off the disposal at the electric or service panel. Disconnect the drain trap from the discharged too. If your dishwasher is connected with your disposal, disconnect it also. Now up of the top of the disposer, you’ll see a mounting ring that’s been installed under your sink’s drain hole. Insert a screw driver into that mounting ring just to the right in one of the three mounting lugs. Or turn it counter clockwise by hand to release the disposer from the mounting ring. The disposer is heavy, so once you release it, it’ll fall freely so before you unhook the disposer assemble some support or place some books or something else under the disposer to prevent from falling.

3. Surprise! Guess what, most new disposals don’t have any cord and plug inside their box. But nothing to worry about, your old one has the cord and plug, so you can remove the whole assembly and use them for your new one. Or you can buy a new cord and plug for your new one, and you can find them in any wire store or in the store from where you bought your new one.
Some people are not comfortable with making electrical connections, if you are one of them you can buy a disposal that already has a cord and plug attached with it or you can ask for any electrician for do the connection work.

4. Different disposals have different sizes of discharge tubes. Your old discharge tube won’t probably fit with the new one because it’s could be too long for the new one. If it’s too long for the new one, simply connect it with the disposal Mark it down where it’ll fit perfectly and cut it down with some hacksaw. And if your are unlucky, and the old one is too short for the new one, you have to go to the store and buy a perfectly sized tube for the new one.

4. Now you have to remove the electrical cover plate. To do so turn the disposer upside down and disconnect the disposer from the power supply. Again! Make sure to turn off the power. Ok if the power is turned off loosen the screws and remove the wires from the disposer.

5. Also, if you are replacing the disposal with a similar model you may be able to keep the existing mounting assembly. And if it’s not a similar model you have to replace that. Remove the snap ring and the whole mounting assembly will come out from the sink’s flange. To remove the existing mounting assembly hardware loosen the three screws with a screwdriver. Remove the flange from above the sink and remove any old plumber’s putty with a knife.

6. Now reverse the process and install the new disposal. Apply a new rope of plumber’s putty to the new flange and press it firmly and place. You can place your disposer on the top the sink to help it hold the sink flange into place.

7. From below insert a gasket over the flange then a second flange and then the mounting ring. Here’s the tricky part, hold all of these items in place while inserting the snap ring. Now tighten the screws evenly and firmly against the backup flange.

8. Flip the disposer over and remove the electrical cover plate, pull the wires out and connect white to white and black to black or red using wire nuts. Then connect the grounding wire with the green screw. Push the wires back into the disposer and replace the electrical cover plate.

9. Many disposer units will come with discharge tube and clamp they are specially designed for reducing vibration. And if the new one doesn’t come with the tube reconnect the discharge tube from your old one.

10. Now lift the disposer up to the mounting ring and line the three mounting taps up with slide ramps on the rings. Turn the mounting taps clockwise until the disposer locks and place on the ring. Now connect the discharge tube with the disposer.

11. If you are done finishing all the process now turn the power back on filling the sink with water and test for leaks.
