Garbage Disposal Replacement: DIY or Call a Plumber?

February 6, 2025

A functional garbage disposal is the most essential fixture in a modern kitchen, reducing food waste disposal. However, like all other appliances, it also wears out and needs replacement. When its disposal breaks down or becomes non-functional, there is a tough decision: whether to do the job himself or hire a professional plumber. In this blog post, we will tell you about the pros and cons of replacing a garbage disposal yourself vs. hiring a plumber to find out which one is the best solution.

When to Replace a Garbage Disposal?

Before you decide how to replace your garbage disposal, it would be good to determine if it needs replacing. Common reasons for this include:

• Clogs: If the disposal clogs frequently, even after proper use, it is time to replace it.
• Odors: Food bits stuck in an old unit create persistent odors that cleaning cannot eliminate.
• Leaks: A cracked or damaged unit can leak water and cause damage to the cabinet or floor.
• Noises: Grinding, rattling, or loud humming sounds can indicate internal component failure.
• Inefficiency: If your garbage disposal takes longer to grind food or jams frequently, this may be a sign of aging.

If any of these symptoms are present, it’s probably time for replacement. The next decision is whether to do a DIY installation or hire a professional.
