What Happens During a Garbage Disposal Replacement?

The DIY culture, especially when it comes to plumbing installations, has done a number on the safety and reliability of household plumbing fixtures. We get it—it’s thought to be a way to save money and maybe achieve a sense of accomplishment. Unfortunately, plumbing installations are rarely as simple as they appear online. In fact, improper installations are not just costly; they can also jeopardize your safety. Fixtures like garbage disposals require professional expertise, extensive experience, and specialized tools.

There are many misconceptions regarding what happens during a garbage disposal replacement. In today’s blog post, Mr. Rooter Plumbing looks into the replacement process to help you understand what happens during the job. The information in this article will help you plan thoroughly for the replacement and avoid unexpected surprises. Remember, Mr. Rooter Plumbing is the name you can rely on when you need a local plumbing company offering garbage disposal replacement in McGregor.

  • Initial Inspection and Assessment

Like with other fixture replacements, the process begins with an assessment, where a licensed plumber inspects your existing disposal to confirm that replacement is the best option. This includes checking for a burned-out motor, persistent leaks, severe rust, or frequent breakdowns.

  • Choosing the Right Garbage Disposal

Once replacement is confirmed, the next step is selecting the right garbage disposal for your home. Your plumber will help you choose based on factors such as motor horsepower, household size, cooking habits, noise preferences, and budget. Larger households or frequent cooks, for example, require higher-horsepower disposals that handle food waste more efficiently.

  • Safe Removal of the Old Disposal

After a new unit is selected, the plumber will disconnect and remove the old garbage disposal. They will shut off the power supply, detach the disposal from the mounting assembly, and disconnect drain and dishwasher lines if applicable. The removal process may vary depending on the brand and model of the existing appliance, but these are the standard steps for most units in homes. Proper removal is essential to prevent damage to the sink, plumbing, or electrical components.

  • Preparing the Sink and Connections

Before installing the new disposal, the plumber cleans the sink flange and inspects seals, gaskets, and mounting hardware. If any components are worn or damaged, they may be replaced altogether to ensure a secure and leak-free installation. This preparation step helps extend the lifespan of the new disposal and prevents future issues.

  • Installing the New Garbage Disposal

The new garbage disposal is then mounted and secured to the sink. The plumber connects it to the drain line system, aligns the appliance correctly, and completes all electrical connections. If your dishwasher drains through the disposal, that connection is also properly installed to prevent backups or leaks.

So, there you have it. These are the five steps most plumbers follow to replace garbage disposals. As you can see, this is not a DIY job. There’s no number of online tutorials or step-by-step videos that can replace the training and experience of a professional plumbing service. If it’s time to replace your aging garbage disposal, leave the job to a reputable plumbing company.
