Tired of scraping plates? A garbage disposal handles those leftover food bits, leaving your kitchen looking spick and span with less effort. However, if you’re considering installing your garbage disposal, there are a few key points to consider. Hooking up a garbage disposal looks easy, but folks often make errors. These mistakes cause leaks, strange noises, or the whole thing simply quits. Trust us, you'll be glad you sidestepped these plumbing errors, saving yourself hours, dollars, and a whole lot of stress, regardless if you're doing the work or paying someone else. If you're not sure where to start, a team like Mr. Rooter Plumbing can show you how to fix it, or we can simply do the work.
1. Forgetting to Disconnect the Power
This might seem like an obvious step, but it's easy to forget. Before touching anything under your sink, always turn off the power at the breaker box. Some people think flipping the wall switch is enough, but it’s not. There could still be power running to the wires.
Working with electricity near water is dangerous. You could get shocked, or worse. Ensure that the power is off before starting the installation. If you're unsure how to do this safely, it's wise to contact a plumber in Hendersonville, TN or a licensed electrician for assistance.
2. Not Matching the Sink and Disposal Size
Not all garbage disposals are compatible with all sinks. If you buy a disposal that’s too big for your sink, it won’t line up correctly. That can cause leaks or force you to cut and bend pipes in weird ways. This makes the system weak and more likely to fail.
Before you purchase your unit, measure the space under your sink. Check the width, height, and depth. Read the disposal box carefully to make sure it fits your kitchen setup. A trusted plumbing repair service can also help you pick the right size and model for your sink.
3. Skipping the Plumber’s Putty
You might be in a rush to get the job done, but skipping plumber’s putty is a big mistake. This soft, clay-like stuff is what seals the flange — the part that connects the disposal to the bottom of the sink. Without it, water can leak around the edges and cause damage to your cabinets or floor.
Some people try to use silicone instead, but it’s not always the best choice for this job. Plumber’s putty is easy to apply, adjust, and clean up if you make a mistake. Using the right sealant is a small step that makes a big difference in the success of your garbage disposal installation.
4. Not Aligning the Mounting Ring Correctly
The mounting ring securely holds the disposal in place at the bottom of the sink. If this ring isn’t lined up or tightened properly, your disposal may rattle, vibrate, or even fall off.
When you’re installing the unit, take your time with the mounting hardware. Make sure all pieces are secure and centered. Some people tighten one side more than the other, which causes the unit to tilt. That puts pressure on the pipes and causes leaks over time. If you're unsure about the process, calling Mr. Rooter Plumbing is a good idea. Their trained professionals can get it done right the first time.
5. Ignoring the Drain Connection
This part is often missed, especially when the old unit is being replaced. When you connect the disposal to the drain, ensure the pipes align properly. A poor connection will cause leaks or clogs. If your dishwasher is connected to the disposal, be sure to unplug the plug inside the connector port. If you forget this step, your dishwasher won't drain.
This is where hiring a skilled plumbing repair service can be truly beneficial. They know what to look for and how to adjust the drain lines without damaging anything. A bad drain connection can also lead to water backing up into your sink or leaking into your cabinets.
Know When to Call a Pro
Some homeowners are comfortable doing this type of work themselves, but there’s no shame in asking for help. A licensed plumber has the tools and expertise to ensure your system is installed safely and correctly. Getting it done right the first time means you won’t have to deal with costly repairs later.
If you're replacing an old unit, it’s also a good time to check for other potential problems, such as rusted pipes or loose seals. Mr. Rooter Plumbing is known for its professional and thorough work, and can handle those issues during the same visit.
Avoid the Headaches and Get It Done Right
