If you’re considering a new garbage disposal or want to get the most out of your current one, this guide will help you make smart choices and support long-term performance. Be sure to also read our earlier post, “6 Warning Signs You Need Garbage Disposal Repair.”
Understanding Disposal Types & Power Levels
When selecting a unit, two major factors matter:
Feed Type
- Continuous-feed: The most common variant. You switch it on and off while running water.
- Batch-feed: Only works when a cover or stopper is placed—adds an extra safety layer.
Motor Power (Horsepower)
- ⅓ HP – Suited for basic kitchens or light usage
- ½ HP – Good for small to medium households
- ¾ HP – More robust for larger families and frequent use
- 1 HP and above – Heavy-duty garbage demand, tougher waste
Larger motors make fewer clogs and handle tougher scraps more easily.
What to Watch for During Installation
Installing a disposal properly is key so it runs well:
- Remove the existing unit and carefully disconnect plumbing & wiring
- Clean the sink flange thoroughly
- Install and seal a new flange with plumber’s putty (or equivalent)
- Mount the disposal securely to the flange
- Attach drain lines and dishwasher hose (if relevant)
- Wire per code, connect ground, test power
- Run water, test operation, and check for leaks

Maintenance Tips to Maximize Lifespan
A few smart habits can drastically reduce repair needs:
- Use cold water constantly while grinding and for 10–20 seconds after
- Don’t overfeed the unit—feed small amounts at a time
- Avoid putting these items down the disposal:
- Stringy/fibrous vegetables (celery, corn husks)
- Large bones or pits
- Grease, oil, fat
- Coffee grounds in excess
- Egg shells & nutshells (they can dull blades or clog)
EatingWell+1
- Clean regularly with ice cubes, coarse salt, or citrus peels; deep clean monthly with baking soda + vinegar
The Spruce - Run the unit daily even with little waste to prevent rust and keep O-rings free
The Spruce - Check for leaks under the sink or around the flange
- Listen closely for humming or odd sounds; address them early
By staying proactive, you reduce the chance of needing major garbage disposal repair or installation.
Cost Considerations & When to Replace
Here’s what to expect when comparing repair vs. new unit:
- Repair costs depend on parts (seals, wiring) and labor
- A new disposal (mid-range) plus installation may fall into a broader budget
- If your current unit is repeatedly failing, replacement often gives better ROI
- When you choose a modern unit, you also gain improved performance and quieter operation
(Rates vary depending on model, horsepower, materials, etc.)
Summary & Next Steps
- Match the unit’s horsepower and style to your household needs
- Ensure installation is done carefully to prevent leaks or vibration
- Stick with consistent maintenance to avoid breakdowns
- Stay alert for warning signs (from Post 1) that may call for repair
- When in doubt, choose a reputable provider for repair or installation
