Product review (5 stars): InSinkErator Baffle
My disposal rubber guard was looking terrible and hardly functioning after 14 years. Most of the rubber 'fins' had broken off and food came gushing up when I turned it on, never mind the loud noise. My plumber suggested this product after confirming that my disposal was in fact an InSinkErator mechanism, even though it has a different brand name on the rim. If yours is old but not leaking, etc, try this baffle rather than having a plumber take apart your disposal, risking opening a can of worms. It truly is a three minute fix, kills the noise, holds back the grinding food, and looks great. Just snip off the remaining rubber parts on your existing guard, clean the gook out from under the rim, and ease in the new one on top of the old rim. Everything should be this easy and inexpensive! It's also easy to pull out to clean periodically.
