Your Simple Guide to InSinkErator Sink Baffles & Stoppers
The sink baffle (also known as the stopper or splash guard) is one of the most overlooked parts of your entire garbage disposal system — and also one of the most important. It controls splash-back, keeps noise down, improves grinding performance, and helps maintain a clean, odor-free sink.
This quick micro-guide gives you everything you need: what a baffle does, how it works, which one fits your disposal, and when to replace it.

✔ What a Sink Baffle Actually Does
- Reduces noise: The soft rubber fins act as a sound barrier, keeping disposal operation quieter.
- Prevents splash: No more dirty water erupting back up when you turn on the disposal.
- Improves grinding efficiency: Helps guide food downward into the grind chamber.
- Blocks odors: Limits smells from rising through the drain.
- Keeps utensils out: The partial seal stops forks/spoons from dropping into the unit.
✔ When You SHOULD Replace Your Baffle
Most people don’t know this part is even removable — but it is. Over time, the rubber breaks down, stiffens, or traps buildup.
- Cracks or tears in the rubber
- Persistent sink odors even after cleaning
- Increased splash-back
- Noticeably louder disposal noise
- Food sticking to the fins
InSinkErator recommends replacing the baffle every 1–2 years depending on usage.
✔ Which Sink Baffle Fits Your Disposal?
Most InSinkErator disposals use one of two standard baffles:
- Quiet Collar Sink Baffle (Evolution Series) – for Evolution, Pro Series, and Select models.
- Standard Sink Baffle (Badger/Power Series) – for most Badger and Power models.
Note: Some models include the baffle integrated into the mounting system. For those, you must purchase the correct replacement part (not a generic rubber insert).

Frequently Asked Questions
Do all InSinkErator models use the same baffle?
No. Evolution/Pro models use the Quiet Collar type, while Badger/Power models use the standard design.
Can I run the disposal with no baffle installed?
You can — but expect water to shoot upward, more noise, and higher risk of small items falling in. Not recommended.
How do I remove the baffle?
Just lift it straight out. No tools required.
✔ What About the Sink Stopper?
The sink stopper is the companion piece to the baffle. While the baffle stays in place during normal use, the stopper is what you use to seal the sink for washing dishes or holding water.
InSinkErator stoppers are simple but important — especially if you regularly soak dishes, rinse produce, or want to prevent small items from slipping into the disposal when it’s not in use.
What a Stopper Does
- Seals the drain so you can fill the sink with water.
- Blocks utensils and food scraps when the disposal isn’t running.
- Provides a tighter sink seal than using a towel or rubber plug.
- Improves safety: no accidental disposal drops.
Most InSinkErator stoppers are universal-fit, but some models use a deeper or tighter design depending on the flange and baffle shape.
When to Replace Your Stopper
- Leaking water when the sink is filled
- Warped or hardened rubber edges
- Damaged handle or loose center post
- Stains or odors that won’t wash off
Like baffles, stoppers are inexpensive and usually last 1–2 years depending on use.

| Part | Purpose | Stays Installed? |

| Sink Baffle | Reduces noise, stops splash, guides food into grinder | Yes — stays in during operation |
| Sink Stopper | Seals sink for water, blocks items when disposal isn’t used | No — only placed when needed |
