Planning Your Installation: Assessing the Space and Gathering Supplies
Before you even touch your new garbage disposal, careful planning is essential, especially when working in a confined area. This section focuses on evaluating your space, gathering the necessary tools, and understanding the key components of your disposal unit.
- Space Assessment: Measure the available space under your sink meticulously. Note the distance between pipes, the sink drain, and the wall. Take photos for reference. Consider whether you’ll need to reposition any pipes to create more room. A poorly planned installation can lead to hours of unnecessary frustration.
- Gather Tools and Supplies: This includes adjustable wrenches, pliers, a basin wrench (essential for tight spaces), plumber’s putty, slip-joint pliers, a bucket, safety glasses, and work gloves. A flashlight and potentially a small mirror might be helpful for visibility in tight spots. Make sure you have the correct size of connecting tubes and adaptors.
- Understanding Disposal Components: Familiarize yourself with the parts of your specific disposal model. This includes the motor housing, the disposal chamber, the mounting assembly, the sink flange, the inlet and outlet drain pipes, and any electrical connections. A basic understanding of each part will significantly speed up the installation process.
Preparing for Installation: Disconnecting the Old Disposal
This section details the safe and efficient removal of your old garbage disposal, which is the first step towards installing the new one. It’s crucial to proceed carefully to prevent leaks and damage to the pipes.
- Turn off the power: Locate the circuit breaker controlling the power to your garbage disposal and switch it off.
- Disconnect the electrical wiring: Carefully disconnect the wires from the disposal unit. Take a picture or note the wiring configurations for easy reconnection.
- Disconnect the water supply lines: Use pliers or a basin wrench to disconnect the inlet and outlet water lines. Be ready for some water to spill, so have a bucket handy.
- Disconnect the drain pipes: Using slip-joint pliers, carefully loosen and disconnect the drain pipes from the disposal unit. These connections usually involve a slip-nut.
- Remove the old disposal: After disconnecting everything, you can carefully remove the old disposal unit from its position under the sink.

Case Study: Tight Space Installation Success
In one instance, a homeowner with a severely cramped sink cabinet managed a successful installation by carefully removing a nearby pipe bracket and repositioning the hot water pipe. This freed up enough space to comfortably maneuver the disposal and connect all plumbing lines. The total time for installation was 2.5 hours.
