As a homeowner, a broken garbage disposal can be a real headache. But before rushing out to buy a pricey new disposal, don‘t despair – many cracked units can be fixed with a few handy tips. In this ultimate guide, we‘ll explore everything you need to know as a homeowner about assessing and repairing cracks in your garbage disposal.
With the right approach, you can often get your disposal working again and save the cost of replacement. I‘ll share professional tips on spotting issues, making repairs, maintenance to prevent future cracks, and when to call in an expert. Let‘s dive in!
How to Thoroughly Inspect Your Disposal for Cracks
The first step is a thorough inspection to locate and identify any cracks. Here‘s a simple process I recommend:
- Unplug the disposal and shut off electricity at the breaker
- Wear eye protection for safety when looking closely
- Check the outside housing, seals, grinding parts, and drain connections
- Use a flashlight to illuminate all areas
- Look for small hairline cracks up to large split seams
- Note any water leaks, damage, or misalignment
Taking the time to carefully inspect will reveal even small cracks and let you assess the repairs needed.
What Typically Causes These Cracks Over Time
In my experience as a home renovation professional, most garbage disposal cracks stem from a handful of common causes:
Clogs
Blocked food buildup and debris put strain on the internal components, often resulting in cracks from the excess pressure.
Foreign Objects
Dropped items like silverware, rocks, or bottle caps get lodged in the grinding parts and can crack the housing when the unit runs.
Excess Force
Pushing down hard with hands or objects to clear a stuck item adds extreme stress that can literally crack the disposal.
Age and Wear
After years of use, the grinding parts and seals weaken and become more prone to cracking from vibration and friction.
Improper Installation
If the original install was not done correctly, normal use can eventually lead to cracked joints or connections.
Understanding the root cause provides useful context on the repairs needed. Next, let‘s explore your options.
When DIY Crack Repairs Are Possible
Many minor cracks are an easy fix with basic tools and materials:
Patching Small Cracks
For cracks less than 1⁄4 inch wide in the housing, apply an epoxy adhesive or plumber‘s sealant per package instructions. Allow to fully cure before using.
Replacing Gaskets
If cracked or worn out gaskets are causing leaks, remove and install new gasket seals to stop water loss.
Tightening Connections
A wrench can re-tighten leaky, loose flange or pipe connections causing drips or cracks.
Unclogging the Unit
Clearing out packed sticky debris removes strain on components and may seal small cracks.
As you can see, many minor disposal cracks can be addressed with basic tools and sealants. Moving on, let‘s look at more complex fixes.
Evaluating Cost of Repair vs Replacement
More involved cracks require removing and disassembling the unit to repair or replace internal parts. For major damage, this often costs over 50% of a new disposal. Here are a few things to consider when weighing repair vs replace:
| Repair Considerations | Description |
|---|---|
| Repair Complexity | Simple fixes like seals can be DIY, but internal repairs often require a pro |
| Part Availability | Hard-to-find parts for old models favor replacement |
| Repair Cost | Compare repair quote to replacement cost |
| Unit Age | Extensive repairs on old disposals may not be worth it |
In general, I‘d recommend repairing minor issues but replacing disposals over 10 years old with extensive cracks or damage.
Signs You Should Call a Pro for Repairs
While I‘m always in favor of DIY when possible, some garbage disposal repairs do require a professional. Here are some indicators to call a pro:
- Visible exterior cracks wider than 1⁄4 inch
- Leaks persisting after gasket replacement
- Grinding components failing
- Damaged, frayed wiring
- Unsure of issue or repair steps
With training and proper tools, handymen and plumbers can safely tackle repairs beyond most DIY skill levels. They can also provide guidance on whether your unit is repairable or needs replacing.
Selecting a New Disposal
If your cracked disposal can‘t be fixed, choosing the right replacement model is key. Here are the most important features to look for:
| Replacement Tips | Details |
|---|---|
| Match Horsepower | Pick same HP rating or higher for needed grinding power |
| Proper Opening Size | Ensure it fits existing sink flange and drain lines |
| Pre-installed Cord | Saves installation work if cord is already attached |
| Reputable Brand | Stick with reliable brands like InSinkErator or Waste King |
| Added Features | Consider useful extras like longer warranty, quiet operation |
With some disposals, you can also replace just the grinding chamber or housing and reuse the motor to save money.
Maintaining Your Disposal
Preventing cracks and other damage comes down to proper maintenance. Here are my top tips as a home professional:
- Run plenty of cold water before, during, and after using the disposal
- Avoid putting fibrous foods like celery down the drain
- Grind ice cubes occasionally to clean blades
- Use a drain cleaner tool monthly to remove grime
- Have a pro inspect annually to spot wear
Proper use and care are crucial for getting the longest possible life from your garbage disposal.
I hope these professional tips help you evaluate whether to repair or replace a cracked garbage disposal. With some basic DIY fixes, many cracked units can keep functioning. But know when repairs are best left to a trained handyman. With the right knowledge, you can make the best choice for your home and budget. Let me know if you have any other disposal questions!
