Identifying Your InSinkErator Model
Knowing your InSinkErator model is crucial for ordering the correct replacement. This section explains how to locate the model number, usually found on a label on the unit itself. This information will help ensure the replacement process is smooth and the new unit is compatible with your plumbing system.
- Locate the model number: Check the underside of the disposal unit or the top for a sticker containing the model number.
- Record the model number: Write it down or take a picture to ensure easy access when ordering a replacement.
- Research your model online: Use the model number to research the specific specifications and installation instructions for your InSinkErator.
Disconnecting the Old InSinkErator
This section provides a step-by-step guide to safely disconnecting the old garbage disposal. It includes detailed instructions on disconnecting the power, water lines, and mounting assembly. Accurate disconnection is essential for a successful and safe replacement.
Disconnecting the Electrical Supply
Double-check that the power is OFF. This is incredibly important to prevent electrical shock. The power switch in the disposal itself is not always sufficient; use the circuit breaker to ensure it’s off before proceeding.
- Verify power is OFF using a voltage tester.
- Disconnect the electrical wires: Carefully disconnect the wires from the disposal, taking note of their connection points for reassembly.
- Secure loose wires: Use electrical tape to secure any loose wires to prevent accidental contact.
Disconnecting the Water Supply
Preventing water damage is critical. Properly disconnecting the water lines will minimize mess and prevent potential water damage during the replacement.
- Turn off the water supply: Turn off the water supply valves under the sink to both the hot and cold water lines connected to the disposal.
- Disconnect the water lines: Carefully loosen and disconnect the water supply lines from the disposal, using a basin wrench to help avoid damage. Have a bucket ready to catch any remaining water.
- Clean up any spills: Immediately clean up any water that may have spilled.
Removing the Mounting Assembly
This subsection details removing the old disposal from the sink. The process involves removing the mounting assembly and disconnecting the discharge pipe. This section also provides tips for dealing with stubborn connections.
- Loosen the mounting assembly: Carefully loosen the mounting ring that secures the disposal to the sink.
- Remove the disposal: Once the mounting assembly is loose, carefully lift the disposal out of the sink.
- Disconnect the drainpipe: Disconnect the drainpipe from the disposal.
Installing the New InSinkErator
