If you need to connect the garbage disposal to an electrical outlet, wire strippers will be necessary. They allow you to safely remove the insulation from electrical wires without damaging the conductors inside. Choose a pair of wire strippers designed for the gauge of wire you will be working with.
Preparing the Sink: Removing the Old Unit
Before you begin installing your new garbage disposal, you need to remove the old unit. Here’s a step-by-step guide on how to do it:
Disconnecting the Power
Safety first! Before you do anything, make sure to turn off the power to the garbage disposal at the circuit breaker or fuse box. This will prevent any electrical shocks while you’re working.
Draining the Water
Next, you need to drain the water from the disposal. To do this, put a bucket under the sink and open the drain plug on the side of the disposal. Let the water drain out completely.
Disconnecting the Plumbing
Now, it’s time to disconnect the plumbing. There are usually two pipes connected to the disposal: the sink drainpipe and the dishwasher drainpipe (if you have one). Use a wrench or pliers to loosen the nuts on the pipes and disconnect them. Be careful not to damage the pipes or the disposal.
Removing the Mounting Bracket
The disposal is typically held in place by a mounting bracket. Locate the bracket and remove the screws that hold it in place. Once the bracket is removed, you can lift the disposal out of the sink.
Removing the Old Gasket
Once the disposal is out, there will be a rubber gasket between the flange and the sink. Remove the old gasket and clean the flange to prepare it for the new disposal.
Installing the Mounting Bracket
Now that the hole is cut, it’s time to install the mounting bracket. This is a metal bracket that will hold the garbage disposal in place.
To install the mounting bracket, follow these steps:
1. Attach the mounting bracket to the garbage disposal.
Most garbage disposals come with a mounting bracket that is attached to the disposal with screws. If your disposal did not come with a mounting bracket, you can purchase one at a hardware store.
2. Position the mounting bracket over the hole in the sink.
Center the mounting bracket over the hole in the sink and align it with the screws that are holding the sink in place.
3. Secure the mounting bracket to the sink.
Using a screwdriver, tighten the screws that are holding the mounting bracket in place. Be sure to tighten the screws securely, but do not overtighten them. Overtightening the screws can damage the sink or the mounting bracket.
| Tip: |
|---|
| If the mounting bracket does not fit snugly against the sink, you can use a shim to fill the gap. A shim is a thin piece of material, such as a washer or a piece of cardboard, that is placed between the mounting bracket and the sink. |
Once the mounting bracket is secure, you are ready to install the garbage disposal.
Connecting the Disposal to the Sink
Once the disposal is mounted, it’s time to connect it to the sink. This involves attaching the drainpipe, dishwasher hose, and electrical cord.
Attaching the Drainpipe
The drainpipe is a flexible pipe that connects the disposal to the sink drain. To attach the drainpipe, you will need to:
- Loosen the nuts on the disposal discharge tube using a wrench.
- Slide the drainpipe onto the discharge tube and tighten the nuts.
- Connect the other end of the drainpipe to the sink drain.
Attaching the Dishwasher Hose
If you have a dishwasher, you will need to attach the dishwasher hose to the disposal. To do this, you will need to:
- Locate the dishwasher drain connection on the disposal.
- Connect the dishwasher hose to the drain connection.
- Tighten the hose clamp.
Connecting the Electrical Cord
The electrical cord connects the disposal to the power source. To connect the electrical cord, you will need to:
- Locate the electrical junction box on the disposal.
- Connect the electrical cord to the junction box.
- Tighten the screws on the junction box.
Once the drainpipe, dishwasher hose, and electrical cord are connected, the disposal is ready to use.
Connecting the Plumbing: Drain and Water Supply
Discharge Pipe
Locate the discharge pipe under the sink and insert it into the outlet port of the garbage disposal. Tighten the slip nut by hand, then use a wrench to secure it further. Ensure the connection is snug but avoid overtightening, as this can damage the disposal.
Drain Line
Connect the drain line from the disposal to the drainpipe under the sink. Use a 1-1/2-inch diameter drain line for optimal flow. Tighten the connection with a wrench or pliers, ensuring it is secure.
Water Supply
Connect the water supply line to the inlet port of the garbage disposal. Use a 3/8-inch diameter water supply line and attach it firmly. Turn on the water supply and check for any leaks. If any leaks occur, retighten the connections or replace any faulty parts.
Electrical Connection
Consult an electrician or follow the manufacturer’s instructions for safely connecting the garbage disposal to a power source. Ensure the circuit is properly grounded and that the garbage disposal is protected by a circuit breaker.
Garbage Disposal Switch
Install a garbage disposal switch that will activate the disposal when you press it. Choose a switch that is specifically designed for garbage disposals and follow the installation instructions provided with the switch.
Test the Disposal
Once all connections are complete, turn on the water supply and press the garbage disposal switch to test its functionality. Listen for any unusual noises or vibrations that may indicate an issue requiring attention.
Wiring the Disposal: Electrical Connections
