Why Is My Garbage Disposal So Noisy?

A garbage disposal is a handy appliance in the kitchen, as it makes food waste disposal more convenient and saves you time. However, a garbage disposal might start producing unusual noises, which may indicate a problem with the appliance that needs to be addressed.

Foreign Objects

Sometimes, foreign objects like pieces of utensils can get stuck in the garbage disposal and make noise as the blades try to grind them up.

It was a late Saturday night. We had a super stubborn clog in some old galvanized pipes. Mr. Rooter send out Phil. Phil was great! He found the problem pretty quick.

Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

I just wanted to say James did a great job at my house. Excellent service, professional and very nice. Thank you so much for helping me with my plumbing problem. Did wonderful job.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

Why Is My Garbage Disposal So Noisy?

Here at Mr. Rooter Plumbing, we offer reliable garbage disposal repair and replacement services. In this article, we will highlight some of the reasons why a garbage disposal may be making unusual noises and what the noises might indicate.

Loose Blades

If the blades in your garbage disposal are loose, they can rattle around and make unusual noises. This is often caused by wear and tear over time.

Faulty Mounting

If the garbage disposal isn't mounted properly, it can vibrate against the sink or surrounding cabinets, which can create noise.

Wo Out Motor Bearings

If the motor bearings in your garbage disposal are wo, they can create a grinding or whirring noise as the motor runs. The solution to wo-out motor bearings is replacing the unit.

Clogs

If the garbage disposal is clogged with food or other debris, it can create a humming or buzzing noise as the motor tries to tu.

Common Garbage Disposal Noises

Here are some common noises that garbage disposals can make and what they might indicate:

Grinding Noise

A grinding noise is a common sound that garbage disposals make when they're working properly. This sound occurs when the blades are grinding up food waste. However, if the grinding noise is louder than usual, it could indicate that the blades are wo down or there is a foreign object stuck in the unit.

Whirring Noise

A whirring noise can occur when the garbage disposal motor is running but the blades aren't grinding properly. This could be due to wo bearings, a damaged flywheel, or an object has been jammed between the unit's shredder ring and the impellers.

Rattling Noise

A rattling noise can indicate that there's something loose inside the garbage disposal. This could be caused by loose mounting bolts, loose blades, or even a loose piece of hardware. The rattling sounds could also be coming from the motor. It's important to tu off the power and unplug the disposal before attempting to tighten any loose components.

Screeching Noise

A screeching noise is often caused by metal-to-metal contact between the blades and other components. This could be due to wo blades or a loose flywheel. A screeching sound might mean the motor is failing.

Humming Noise

A humming noise can occur when the garbage disposal motor is running but the blades aren't tuing. This can happen if the blades are jammed as a result of a foreign object caught in the blades or if there's a clog in the disposal.
