How Long Does It Take to Install a Garbage Disposal?
Garbage disposals are a handy item to have in the kitchen. Many people install them themselves as all it takes is some plumbing and electrical know how. It should not take more than a couple hours to install a disposal from start to finish. Depending on your skill level and your organization, you can have it done rather quickly. Using this guide, you can have the job done in seven steps.
How to Install a Garbage Disposal for the First Time
Installing a garbage disposal for the first time can be a little intimidating. So, here’s a step by step guide to help you out.
If you still have an old disposer installed, you will need to unplug its power cord from the outlet before you can take it out. In the case that your disposal is hardwired into the circuit, you will have to head to the breaker box and turn off the circuit breaker connected to the area. Because a garbage disposal is an electrical unit around a sink, you want to take the proper safety precautions.
Get down under the sink and make sure that your disposal will fit into the pre-cut drain area. They are pretty standard, but you want to check and make sure.
Next, you need to remove the drains to make room for the new disposal unit. To ensure that the main drain opening is plugged and no leakage will occur, place an old rag into the drain. At the base of the sink’s flange, there is a large nut that needs to be removed. After the nut is gone, push the strainer body through the sink until it pops out. Putty is commonly put around the sink’s opening. Using a flathead screwdriver, remove this putty. Make sure the opening is clean.
Next, the mounting assembly needs to be placed upside down into the space. You need to access the mounting ring, so you will need to loosen all the screws. The mounting assembly (consists of the mounting ring and drain flange) needs to be taken apart, so you will need to remove the ring to accomplish this. Damage to the fiber gasket can occur rather easily, so make sure when separating the parts not to damage it.
Grab some plumber’s putty and place it all around the drain opening. It needs to be firmly in place. Slip the metal ring and gasket over the sink’s flange to prepare for installation. You may want to use a rubber band to hold the ring and fiber gasket in place while putting the mounting ring on the flange. Ensure the ring is above the ring groove and secured into place by the snap ring.
Once everything is in place, tighten the mounting screws drawing the unit closer to the sink. When complete, the unit should be firmly in place. If any additional putty came out from the drain opening flange during these various steps, make sure to clean that up too. Now, you are ready to hook up the electric to the unit. There are a few screws that hold an access cover on the unit. This is located on the bottom. Just unscrew the screws and remove the wires.
Using a wire clamp, pull the electrical wire through the clamp. It’s simply wiring from this point on. Line up the black and white wires to the coordinating ones, and be sure to secure them with wire nuts and some electrical tape. The white lead should go with the white wire from the power cord while the black lead should go with the black cord wire. Lastly, hook up the ground wire. The wires need to be pushed into the access hole and should be tightened with an electrical clamp.
This optional step is meant for garbage disposal installations where the dishwasher drain water runs through the disposer. First, you need to locate the dishwasher inlet in the disposer. Once you found it, remove the knock-out plug from the unit.
Connecting the unit to the drain is the final step. To accomplish this, you need to have a PVC P-trap or discharge tube. Place all the pipes together and tighten. See to it that the discharge tube is aligned with the waste trap from the sink drain. You may now connect the dishwasher line. Take the dishwasher hose and slide it into the nipple. Then, secure the connection with a hose clamp or any other clamp provided for you by the manufacturer.
Also, be sure to use plumbers putty on any new connections. Now, you are ready for business. Just turn on the power, and make sure your unit works. It is a simple job that even an amateur can do.
