Garbage disposals (they are really called garbage disposers, but everybody calls them garbage disposals) can last between eight and 15 years, depending on the quality of the product, frequency of use and care not to abuse it. But if you find yourself in need of a new disposal, here are some factors to consider.
- Space. To state the obvious, make sure there is enough room under the sink for the disposal.
- Motor size. Size is measured in horsepower HP). Bigger units grind better and are generally quieter. Here are some general guidelines, although a lot depends on how frequently you would use it.
- 1/3 HP is appropriate for small households that won’t use it a lot.
- ½ HP is for 2 to 4-person households with normal eating habits.
- 3/4 HP is for households of 3-5 people with medium use.
- 1 HP is for larger families or those that cook frequently.
- Grinding material. Grinding chambers are made of stainless steel or galvanized steel. Stainless steel is more expensive but can handle a wide variety of food waste including fibrous materials and bones. Stainless steel is also more durable and resistant to rust and corrosion. Galvanized steel, while less costly, is not as durable and is prone to rust and corrosion.
- Continuous feed vs. batch feed. One is not necessarily better than the other; it’s really a matter of personal preference. The table below outlines the differences:
| Continuous feed | Batch feed | |
| How it works | Activated by a switch and continuously grinds waste as it is added, Does not have a stopper. | Requires a stopper before activating. Grinds food in batches. |
| Ease of use | Easier to use; clean up as you go | Harder to use as you need to load and activate in batches. |
| Availability | More available | Possibly less available |
| Price | Generally less expensive | Generally more expensive |
| Power | More powerful | Less powerful, requiring more time to dispose of large quantities |
| Noise | Louder | Quieter |
| Safety | Potential hazard if objects fall into the disposal while running | Safer as it requires a stopper before running |
The general rule of thumb is to select a continuous feed unit as it is more convenient, as long as you can tolerate the noise. If you value safety or a quieter operation and don’t mind the batch feed, select a batch feed product.
- Anti-jamming. Jam sensors can prevent blockages and prevent premature failure of the disposal.
Finally, while some units promote themselves as DIY for installation, the recommendation is to use a licensed plumber to install the garbage disposal. That way, if anything goes wrong, it is the plumber’s responsibility.
