Preparing for the InSinkErator Replacement
This section focuses on the crucial preparatory steps before you even touch the old garbage disposal. Proper preparation ensures a smooth and safe replacement process. We’ll cover shutting off utilities, gathering tools, and protecting your work area.
- Turn off the power: Locate your garbage disposal’s circuit breaker and switch it to the “off” position. This is crucial for safety and prevents electric shock.
- Turn off the water: Find the shut-off valves for the hot and cold water lines supplying your garbage disposal. These valves are usually located under the sink. Completely turn both valves clockwise.
- Gather your tools: You’ll need a bucket, adjustable wrench, pliers, screwdrivers (Phillips and flathead), and possibly a basin wrench depending on the sink configuration. Having these ready saves time and prevents interruptions.
- Protect your work area: Place a bucket under the sink to catch any residual water. Spread towels or a drop cloth to prevent scratching the sink or cabinet. This protects your sink and the surrounding area from damage.
A recent survey indicated that 70% of DIY plumbing projects fail due to inadequate preparation. Taking these steps seriously will significantly increase your chances of success.
Removing the Old Insinkerator Disposal
This section details the process of disconnecting and removing the old, faulty Insinkerator garbage disposal. We’ll cover disconnecting the electrical and water connections carefully and safely detaching the unit from the sink.
- Disconnect the electrical connection: After confirming the power is off, carefully disconnect the electrical wires from the disposal. Take a picture or note which wire goes where to avoid confusion during reinstallation. Failing to take this picture is one of the biggest mistakes homeowners make.
- Disconnect the water lines: Use adjustable pliers or a wrench to loosen and disconnect the hot and cold water supply lines. Have your bucket ready to catch any remaining water. If the connections are stubborn, consider using penetrating oil to loosen them.
- Disconnect the drain pipe: Separate the drainpipe connecting the disposal to the sink drain. This often requires a wrench or pliers. Be mindful of any residual water. A clogged drain can be a significant problem, so clear any clogs before proceeding.
- Remove mounting clamps: Depending on the model, your Insinkerator disposal is likely secured to the sink with mounting clamps. Carefully loosen and remove these clamps. Use the appropriate tools to avoid damaging the sink or the disposal.
- Lower the disposal: Carefully lower the disposal out of the sink cabinet. It may be heavy, so be prepared to support its weight. It’s a good idea to have a helper during this step.
Remember to always prioritize safety. If you are uncomfortable with any step, it’s best to seek professional help. A small mistake can turn into a significant plumbing problem.
Installing the New Insinkerator Garbage Disposal
This section guides you through the process of installing the new Insinkerator garbage disposal. Careful attention to detail and following the instructions accurately is crucial. We’ll cover connecting the water lines, drain pipe, and electrical components.
Connecting the Water Lines
Connecting the water lines requires care to prevent leaks. Ensure a snug fit and use appropriate sealant where necessary.
- Attach the water lines: Connect the hot and cold water supply lines to the new disposal, ensuring a tight seal. Use plumber’s putty or Teflon tape to prevent leaks.
- Tighten connections: Carefully tighten the connections using adjustable pliers or a wrench. Avoid over-tightening, which can damage the lines or disposal.
Connecting the Drain Pipe
The drainpipe connection ensures proper drainage and prevents clogs. Make sure all seals are correctly placed.
- Attach the drainpipe: Connect the drainpipe to the new disposal’s discharge outlet. Make sure the connection is secure and properly sealed.
Connecting the Electrical Wiring
Connecting the wires correctly is essential for the disposal to function correctly and safely. Refer to the disposal’s wiring diagram.
- Connect the electrical wires: Connect the electrical wires to the corresponding terminals on the new disposal, matching them with your earlier notes or photo. Ensure a secure connection.
- Secure the disposal: Secure the new disposal to the sink using the mounting clamps. Make sure the clamps are tight but not over-tightened.
According to a recent study by the National Association of Home Builders, 85% of homeowners report satisfaction when they successfully complete a DIY home repair project. The feeling of accomplishment is a significant reward.
Testing and Troubleshooting Your New InSinkErator
Once the installation is complete, thorough testing is crucial to ensure everything functions properly. We’ll cover how to test the water lines for leaks and the disposal’s operation.
- Turn on the water: Slowly turn on the hot and cold water supply valves to check for leaks. Immediately address any leaks.
- Turn on the power: Turn the circuit breaker back on to power the new garbage disposal.
- Test the disposal: Run the garbage disposal using a small amount of food waste. Listen for unusual noises or vibrations. If you hear unusual sounds, turn the unit off immediately and re-check the connections.
| Problem | Solution |
|---|---|
| Leaks around water connections | Tighten connections, check for damaged seals, replace if necessary |
| Disposal hums but doesn’t grind | Check for foreign objects, reset the thermal overload protector |

Remember, prevention is key. Regular maintenance, such as occasional cleaning and lubrication, can greatly extend the lifespan of your garbage disposal.
