The Do’s and Don’ts Before Replacing Your Garbage Disposal
October 23,2025

Garbage disposals are modern kitchen appliances designed to enhance convenience, hygiene, and safety. Whether it is residential or commercial buildings, these plumbing appliances play a crucial role in enhancing the overall cooking experience. Unfortunately, common issues like food waste buildup, jams from objects, and foul odors can become frustrating and inconvenient. In such situations, Mr. Rooter Plumbing stands out as the go-to garbage disposal replacement or installation service. With many years of experience, our plumbers in South Jersey understand the complexities of different systems, helping you choose the right system for your needs. If you prefer a more hands-on approach, here are the Do's and Don’ts before upgrading your garbage disposal to ensure a seamless process.

Do’s

Turn Off Power

Before disassembling the existing system, turn off the power at the circuit breaker and unplug it if necessary. Safety is a top priority when it comes to plumbing projects, and garbage disposal replacement is no exception. If you don’t have the basic skills or knowledge to navigate the electrical connections, hire a trusted plumber to handle the heavy lifting.

Follow Manufacturer’s Instructions

Just like most new products, a disposal unit comes with a manual, containing specific instructions based on the model. If you neglect these instructions, breakage or damage during installation will void the warranty and come out of your pocket. Sometimes, manufacturers emphasize that installation should be left to professionals and require evidence of correct placement when using the warranty for repairs.

Use a Professional

The reality is that plumbing projects require extensive expertise and professional-grade equipment to execute correctly. With this in mind, hiring a seasoned plumbing repair service provider can help navigate the process seamlessly. In addition, trained experts are up-to-date on local building codes and regulations, ensuring every step of the project meets professional standards.

Don’ts

Don’t Reuse Old Parts

A common mistake DIY enthusiasts make when attempting plumbing repairs is reusing old parts. Even if components like the sink or pipes appear functional, they may be more susceptible to damage. New garbage disposal parts often come at a cost, but the long-term benefits and potential cost savings make it a worthwhile investment.

Don’t Make Assumptions

Another mistake that homeowners make is assuming new systems are the same as old ones. If you installed the existing system, newer models have specific instructions and unique mounting mechanisms. Before proceeding with installations, inspect the new system to familiarize yourself with its design and components. If the installation requires system upgrades or extensive expertise, it’s crucial to hire professional plumbers.

Don’t Neglect Building Codes

Local building codes and regulations are constantly changing. However, DIY enthusiasts rarely keep up with these changes, leading to non-compliance and costly fines. In severe cases, violations can lead to legal action. The best way to ensure everything is done by the book is to hire a licensed plumbing repair service. As mentioned, professionals are always up-to-date on local codes, saving you time on research.

Why Choose Professional Garbage Disposal Replacement

Although DIY installations may seem straightforward, hiring certified plumbers offers numerous benefits that outweigh any potential cost savings. Highly trained plumbers can prevent costly mistakes like leaks, sink damage, and electrical problems associated with DIY projects. This gives you confidence in the quality of service, ensuring you make the most of your investment.
