At Homewise Plumbing, we’ve helped thousands of homeowners across Greater Victoria and Sooke improve the function and efficiency of their kitchens. From heritage homes in James Bay to modern builds in Langford, we’ve installed, repaired, and advised on just about every type of plumbing fixture imaginable. One question that comes up time and again is whether a garbage disposal unit is a smart addition to the kitchen. While this appliance can offer added convenience, it’s important to understand how it works, what its limitations are, and how to maintain it properly to avoid costly plumbing issues down the line.
How Does a Garbage Disposal Work?
A garbage disposal is installed under your kitchen sink and is connected to the drain. When turned on, a motor spins a grinding plate that pulverizes soft food waste into tiny particles. These particles are then flushed down the drain with water. Despite the name, disposals don’t have sharp blades – just a spinning disc (or impellers) that forces food against a stationary grind ring.
Pros of Installing a Garbage Disposal
1. Convenience
A disposal makes cleanup faster by allowing you to rinse soft food scraps down the drain instead of constantly scraping them into a compost bin.
2. Reduces Food Waste
By sending biodegradable waste through your plumbing, you reduce the amount of food going to landfills, which can help cut down on methane emissions.
3. Cleaner Kitchen
Less food sitting in your bin means fewer odours and less attraction for pests in the kitchen.
4. Adds Value to the Kitchen
Some homebuyers consider a garbage disposal a desirable feature, particularly in renovated or modern kitchens.
Cons of Installing a Garbage Disposal
1. Not Suitable for All Plumbing Systems
Older homes in Victoria (especially those with cast iron or galvanized piping) may not handle ground food particles well. This can lead to clogs or more frequent maintenance.
2. Maintenance and Misuse Issues
Improper use (like putting fibrous or hard food waste down the disposal) can damage the unit or cause blockages in your plumbing.
3. Potential for Odours
If not cleaned regularly, food residue can build up and cause unpleasant smells.
4. Doesn’t Replace a Compost System
For residents committed to composting, a disposal may feel redundant and not environmentally beneficial if overused.
What You Should and Shouldn’t Put Down a Garbage Disposal
Foods you can put down a disposal:
- Soft fruit and vegetable scraps
- Cooked leftovers (in moderation)
- Coffee grounds (small amounts)
- Eggshells (though this is debated; grind with plenty of water)
Foods you shouldn’t put down a disposal:
- Grease, oil, or fat
- Pasta, rice, and bread (they expand with water)
- Potato peels and fibrous vegetables (celery, corn husks, etc.)
- Bones or seafood shells
- Fruit pits or large seeds
- Onion skins
A good rule of thumb: if you wouldn’t chew it easily with your teeth, don’t expect your disposal to either.
Installation & Maintenance Tips
Installation:
Garbage disposals need to be properly installed and wired into your kitchen’s plumbing and electrical systems. Our team at Homewise Plumbing is fully licensed to handle installations, ensuring it meets BC building codes and functions safely.
Maintenance Tips:
- Run cold water while the unit is on to help flush food particles down the line.
- Clean regularly using ice cubes, a splash of vinegar, and baking soda to freshen it.
- Avoid harsh chemicals: they can damage both the disposal and your pipes.
- Don’t overload it: feed food waste in gradually.
Final Thoughts
While a garbage disposal can be a great addition to many kitchens, it’s not a one-size-fits-all solution. For homes in Greater Victoria, especially older ones, you’ll want to make sure your plumbing system can handle the addition. If you’re thinking about installing one, or need help maintaining your current unit, we’re here to help.
