Common Symptoms & Causes
The following symptoms often indicate that your garbage disposal’s splash guard needs to be replaced.
🔨 Pro Tip from Dave
The biggest mistake I see DIYers make is forcing the new splash guard down without fully removing the old one first — always peel the inner flap out completely before seating the replacement. For most standard disposals including InSinkErator Badger models, look for part number 76707 (Quiet Collar Sink Baffle), which fits the Badger series and drops right in without tools. Don’t use a knife to pry the old one out or you risk nicking the disposal flange seal.
- Black rubber flaps are visibly cracked, torn, or missing entirely
- Water and food debris splash back up into the sink during operation
- A persistent foul odor coming from the disposal that won’t go away after cleaning
- The splash guard feels stiff, brittle, or no longer sits flush in the drain opening
These issues are typically caused by normal wear and tear over time, as the rubber material of the splash guard degrades with repeated exposure to heat, moisture, and food waste.
How Much Does This Repair Cost?
Replacing a garbage disposal splash guard yourself typically costs between $10 and $30 for the replacement part. A professional service call for this repair can run $150 to $300 once you factor in labor and fees. By tackling this DIY repair, you could save well over $100 while restoring your disposal’s performance.
Frequently Asked Questions
Do I need to turn off the power before replacing the splash guard?
Yes, always unplug the garbage disposal or switch off the circuit breaker before starting. This prevents accidental activation while your hands are near the unit.
Can I replace the splash guard without removing the entire disposal?
In most cases, yes. The splash guard typically snaps into the drain opening and can be replaced by simply pulling out the old one and pressing the new one into place.
How do I know which replacement splash guard fits my garbage disposal?
Check your disposal’s model number, usually found on a label on the unit’s side or bottom. Use that number to find a compatible replacement part from the manufacturer or a hardware store.

The Splash Guard Replacement That Actually Stops Odors and Debris Splash
If you’ve got an InSinkErator Evolution series disposal, this is the exact part you need—the OEM splash guard design fits tight and seals properly, which is what actually matters when you’re tired of smelling your drain. I always recommend ordering the correct model-specific guard rather than a universal one, since fit issues are what cause comebacks.
What works
- Removable design means you can clean or replace it without tools—just pull and twist, which makes maintenance actually happen instead of getting skipped.
- The upgraded EPDM rubber holds up better than the original flap that came on older units—doesn’t get that brittle, moldy feel after a couple years.
- Dimensions are exact for the Evolution line, so there’s no wobble or gap where water and odors seep back into the sink.
What doesn’t
- Won’t fit Badger series or older InSinkErator models—measure your existing guard or verify your model number first, because incompatible splash guards are the most common wrong-part order I see.
- You still need to hand-clean it regularly; it’s not self-cleaning, and letting it sit with trapped food debris will eventually cause the same mold and stiffness you’re trying to fix.
I once had a homeowner order a universal splash guard thinking it would save money, then spend an hour trying to jam it into the disposal opening—it’s worth the five minutes to verify you’ve got an Evolution series before checking out. Grab the 3 3/8″ Garbage Disposal Splash Guard, QCB-AM Sink Baffle Replacement for InSinkErator Evolution Series, Upgraded Removable Quiet Collar Drain Plugs, Garbage Disposer Accessories, Black and you’ll have the right part the first time.
