Garbage disposals provide a convenient way to grind up food waste so it doesn’t clog pipes or clutter up trash cans. When selecting a disposal for your home, one of the first decisions is whether to get a corded or non-corded model. This comprehensive guide covers the key differences, installation steps, usage tips, and factors to consider when choosing a garbage disposal.
Corded vs Non-Corded Garbage Disposals
The primary difference between corded and non-corded disposals is how they connect to electricity to power the grinding motor.
Corded Garbage Disposals
Corded disposals have an electrical power cord that plugs into a nearby outlet under the sink.
Pros of Corded Models:
- Easier and quicker to install since no wiring required
- Can plug into any standard electrical outlet conveniently located near the sink
- Motors tend to be more powerful and efficient at pulverizing waste
- Simple to relocate if you rearrange your kitchen – just unplug and plug into a new outlet
- Replacing the disposal is straightforward without rewiring
Cons of Corded Models:
- Power cord can look cluttered under the sink
- Limited by location and availability of electrical outlets
Non-Corded Garbage Disposals
Non-corded disposals connect directly to your home’s electrical system without a power cord.
Pros of Non-Corded Models:
- Provide a smooth, seamless look without any visible cords
- Known for their durability and long lifespan
- Permanent hardwired installation allows for heavier duty components
- No need for electrical outlet near the sink
Cons of Non-Corded Models:
- Professional installation required since unit must be wired directly into home’s electrical system
- Relocating or replacing disposal requires some rewiring
Step-by-Step Installation Guide
Installing a garbage disposal involves both plumbing and electrical connections. Here are the key steps:
Pre-Installation
Before starting installation, remember to:
- Turn off power supply at the main circuit breaker panel
- Gather any tools you’ll need – screwdriver, adjustable wrenches, pliers, etc.
- Inspect the sink flange, drain pipe, and P-trap under the sink
- Remove old disposal if replacing an existing unit
Mounting the Disposal Unit
- Follow manufacturer instructions to assemble and mount the new disposal unit
- Position unit correctly under the sink flange with mounting ring adapter
- Use included bolts, screws, and lock washers to securely fasten unit
- Tighten all connections completely to prevent leaks
Electrical and Plumbing Connections
- For corded models: plug power cord into electrical outlet
- For non-corded models: connect wires directly to electrical system
- Attach inlet pipe to disposal inlet and outlet pipe to disposal outlet
- Secure all pipe fittings with clamps; use Teflon tape if necessary
- Check for leaks by tugging on pipes
Finishing Steps
- Run water into disposal and check for leaks
- Press reset button if applicable and test disposal operation
- Review user manual for any other brand-specific installation tips
Usage and Maintenance Tips
- Gradually ease into using your disposal over 2-3 weeks, starting with soft foods. This allows time for break-in period.
- Run cold water before, during, and after grinding to harden fats and move particles down the drain.
- Cut or break up larger scraps to help the disposal work more efficiently.
- Avoid putting extremely fibrous or hard items down the disposal.
- Regularly put ice cubes down the disposal to clean and sharpen the blades.
- Use a degreasing cleaning product periodically to keep the unit smelling fresh.
Key Features To Consider When Buying
When selecting a garbage disposal, keep these features in mind:
- Horsepower – Look for at least 1 HP for adequate grinding ability. Higher is better for tough waste.
- Grind Stages – More grind stages mean smaller particle size for smoother drain flow.
- Feed Type – Continuous feed is convenient but batch feed models are safer.
- Noise Level – Check decibel ratings if noise is a concern. Some models are quieter.
- Materials – Stainless steel components are the most durable and corrosion resistant.
- Size – Make sure to buy the appropriate capacity disposal for your household needs.
With proper installation and maintenance, a high-quality garbage disposal can make waste disposal a breeze in your kitchen for years to come!
