When to Tighten Your Garbage Disposal Blades

A garbage disposal is a convenient appliance that grinds up food scraps to prevent clogs and odours in your kitchen sink drain. The blades inside the disposal do all the hard work of breaking down food particles into tiny pieces.

Over time, the grinding blades can become loose and require tightening for optimal performance.

Signs Your Disposal Blades Need Tightening

There are a few key signs that indicate the blades inside your garbage disposal need to be tightened:

• Leaking – If you notice water leaking from the bottom of the disposal, the blade mount has likely come loose allowing water to escape.
• Loud humming noise – As blades loosen over time, the disposal will start to make a loud humming or vibrating sound when turned on.
• Slow grinding – Loose blades cannot grind food waste as efficiently. You’ll notice the disposal slowing down and not operating smoothly.
• Bad odours – Food particles can get trapped under loose blades and cause unpleasant smells.

Problems Caused by Loose Blades

It’s important to tighten disposal blades as soon as you notice any issues because continued use with loose blades can lead to further problems:

• Imbalance and vibration – Centrifugal force works best when blades are tight. Looseness throws off balance resulting in wobbling and noise.
• Corrosion – Small gaps created by looseness allow water to leak down and erode metal over time.
• Clogs – Food waste can get wedged under loose blades and lead to jams.
• Motor burnout – The motor has to work harder when blades are loose, which could lead to early failure.

How Often to Inspect and Tighten Blades

Routine tightening helps prevent many problems and extends the life of your garbage disposal. Here are some general guidelines on blade maintenance:

• New disposals – Inspect blades after the first month of use. New blades may settle and need tightening.
• Regular use – Check blade tightness every 4-6 months. Give them a tighten whenever signs of looseness appear.
• Heavy use – For large families or frequent use, inspect blades every 2-3 months.
• When installing – Always check that blade mounting bolts are tight after attaching a new disposal.
• After jams – If you’ve had to manually turn the disposal to clear a clog, check the blades afterwards. The clog may have caused loosening.

Staying on top of blade tightness will help keep your garbage disposal running smoothly for years.

Take a few minutes to inspect the blades periodically and tighten them as needed. Your disposal will operate quietly and grind more efficiently.

Preparing to Tighten the Blades in Your Garbage Disposal

Tightening the blades in your garbage disposal is a relatively straightforward DIY task. However, there are some important steps to take in preparation for safely and effectively accessing and tightening the blades.

Safety Precautions

Working inside any appliance requires caution. Here are some tips for safely preparing to work on your disposal:

• Turn off power – Unplug the disposal or locate the circuit breaker and switch off the power before starting any work. Electric shock is a real risk.
• Avoid reaching hands inside – Once the splash guard is removed, resist the urge to stick your hands down into the disposal chamber. Use tools instead.
• Wear gloves – Gloves will protect your hands from sharp edges on the blades or mounting hardware.

Gather Materials

You’ll need a few basic tools for the job:

• Allen wrench or hex key – This is the key tool needed to loosen and tighten the blade mount. Usually, it came with the original disposal.
• Flashlight – Good lighting is essential. You’ll need to see down into the disposal cavity.
• Gloves – As mentioned for hand protection. Heavy rubber gloves are ideal.

Accessing the Blade Assembly

The blade assembly sits down in the grinding chamber of the disposal. Here’s how to gain access:

• Remove splash guard – There is typically a round guard that fits over the sink opening. Remove this plate to expose the top of the grinding chamber.
• Look from top – Peer down with a flashlight to get an initial look at the blade assembly.
• Insert wrench from bottom – You’ll actually insert the Allen wrench up through the bottom, not down from the top.

Once you’ve taken safety precautions and gathered the needed tools, you’ll be ready to proceed with tightening up those loose blades!

Locating the Adjustment Screws on a Garbage Disposal

The key to tightening disposal blades is locating and turning the proper adjustment screws. These screws are typically set into the bottom of the blade assembly but vary somewhat by model.

Screw Locations by Disposal Model

• Badger disposals – Two adjustment screws are accessed from the bottom. Insert Allen wrench into the center.
• InSinkErator – Older models have two screws in the center reachable from below. Newer ones just one screw in the center.
• Waste King – A single screw is centred in the bottom of the blade housing.
• GE disposals – Two adjustment screws located on opposite sides of the lower housing.

Getting a Visual on the Screws

Since the screws are on the underside of the blade assembly, you need to get a visual from below:

• Remove the splash guard on top so you can shine a light down.
• Peer down through the sink drain opening with a flashlight.
• Some disposals have an access panel on the side of the base – open this for a view inside.

Don’t Remove Mounting Assembly!

Warning: Do not remove the entire blade mounting assembly to access screws. This can misalign the blades. Just insert the Allen wrench into the bottom of the chamber to reach screws.

Locating the adjustment screws properly is the first step in being able to tighten disposal blades. Take your time to identify screw placement before attempting to tighten.

How To Tighten Garbage Disposal Blades

Once you’ve located the screw or screws that adjust and tighten the blades, it’s time to get them snugged up. Follow these tips for properly tightening the screws:

Tighten in Small Increments

• Only tighten screws a quarter or half turn at a time then check for tightness.
• It’s easy to overtighten if you crank the screw down too much initially.
• Spinning the adjustment screws clockwise will raise and tighten the blades.

Order for Multiple Screws

• If there are 2 adjustment screws, tighten one a quarter turn, then tighten the other a quarter turn.
• Keep alternating back and forth between screws to evenly raise the blade assembly.
• Tighten a little at a time until both screws are snug.

Testing Blade Tightness

• After each small tightening increment, turn on the disposal to check blade tightness.
• The blades should turn freely with no friction sound.
• If needed, turn the disposal off and tighten screws a bit more.

Re-tightening Over Time

• The tightening process may need repeating over time as blades settle.
• Periodically check blades and re-tighten screws as needed to maintain performance.

With a careful approach, you can dial in perfect blade tightness for smooth operation. Take your time and tighten screws progressively in small turns.

How to Sharpen the Blades

Follow these steps for sharpening disposal blades:

1. Turn off power and unplug disposal for safety.
2. Use the Allen wrench to detach the blade assembly.
3. File the edges of blades in a backwards motion. Go slow to avoid removing too much metal.
4. Give blades a few test grinds by hand to feel sharpness.
5. Clean blades with a rag soaked in soapy water.
6. Reinstall the blade assembly and secure it tightly.

Sharpened blades will restore your disposal’s grinding power. Just be sure to work safely and sharpen blades gradually for the best edge.

Troubleshooting Tips for Tightening Garbage Disposal Blades

Sometimes tightening the blades on your garbage disposal doesn’t go smoothly. Here are some troubleshooting tips for common issues that arise:

What to do if blades won’t tighten with adjustment screws

If turning the adjustment screws has no effect on tightening the blades, here’s how to troubleshoot:

• Confirm you have located the proper adjustment screws. Refer to model instructions.
• The screw or housing threads may be stripped and need replacing.
• There may be blockage keeping the mounting assembly from tightening. Turn disposal on to clear debris.
• The unit may need a new mounting gasket. Leaks indicate the seal is damaged.

When to Call a Repair Service

DIY repairs may not be possible if:

• The internal splines that hold the blade assembly are damaged or worn.
• There is damage or cracks in the grinding components.
• You are unable to access or see the blade hardware. Calling a pro may be safest option.

Stopping Leaks After Tightening

Sometimes tightening blades causes leaks around the mounting assembly:

• The mounting gasket likely needs replacement – old gaskets get stiff.
• Back off on tightening and see if leak stops. Overtightening can warp components.
• Food waste may be trapped under gasket. Flush with hot water to clear debris.

Don’t give up if blade tightening proves tricky. There are solutions to most issues. But if major internal damage exists, calling a repair technician is wise.
