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.

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.
