In some cases, it’s more cost-effective in the long run to replace a garbage disposal, but it depends on the specific issue you’re having and the age of your disposal. You should ask a garbage disposal repair tech for a quote to repair your appliance and then see if it would be more worthwhile to replace it. Additionally, garbage disposals last for around 15 years, so if you know your appliance is reaching that age, it’s likely better to pay for a new garbage disposal rather than sink money into repairs.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

The main issue with garbage disposals is clogging. This can mean a clogging of the pipes that expel the food along with water, or a clogging of the mechanical parts themselves. The problem lies in the solution because you can’t easily see clogs if they’re inside the system, and reaching in to dislodge stuck items is a risky proposal. Call a pro and ask what they would do, but if you can’t see the clog easily, and running the unit won’t free it, you need to let a professional handle the fix. 

Garbage disposals are durable appliances that usually last at least eight years as long as you clean and maintain them. It’s relatively rare for a garbage disposal to break on its own, as most malfunctions happen due to user errors, like overstuffing the grinding compartment or damaging the blades by trying to dispose of metal or bone. Eventually, cracks or leaks could develop in the unit, which requires a full replacement.
