Garbage disposals are noisy by nature as you have a very powerful rotary mechanism that is strong enough to break down very tough food that you throw down the sink. However, at some point, they can get a little too noisy to the point where some homeowners are hesitant about turning it on altogether. Older garbage disposal models are very noisy, but newer ones tend to be slightly more muffled. So, if your new garbage disposal has been making more racket than it used to, this could hint at something malfunctioning.
There are many factors that lend to the noisy garbage disposal. First is that one of the parts is either stuck or wedged, keeping the mechanism from properly functioning, thus making a lot of noise. You can try unjamming the garbage disposal using the aforementioned technique with the wrench. However, if this doesn’t help and it’s still very noisy, then a part may have broken, fallen out of place, or may even be missing entirely. This can also be a warning sign, because food scraps like cherry seeds may have found their way into the drain and are damaging the blades.
For broken, misplaced, or missing parts, your best bet would be to contact a plumber. While unjamming using a garbage disposal wrench is easy, fixing and replacing the more intricate parts of the mechanism is far trickier to get right. In this case, it’s best to leave this to the pros. Luckily it’s very easy to book a professional plumber these days so you should have no problem fixing your garbage disposal in the span of a few hours.
