After 4 years of having this on the market, still a defective/chipping product?! What are the other COLOR options out there?** A: I thought this may have been an exclusive club but, I guess not. Mine, oil rubbed bronze, chipped within the first 6 months. I have a brown sink so I was careful not to use abrasives or bleaches, no wire brushes nothing that would scratch or discolor the sink never realizing the drain would chip. Nothing I can do but buy another. **Q: Does this product just snap in or does it require installation?** A: requires installation. Plumbers puddy under the rim and a locking ring from your current disposal should be what you need.Should be an insinkerator brand disposal to insure proper fit. **Q: can this be used with product - InSinkErator QCB-AM Anti-Microbial Quiet Collar Sink Baffle, Black** A: The White version worked great so I assume the Black version is the same size / fit. **Q: Mine doesn't hold water. How can I get new rubber gaskets or something. Its like the plug doesn't fit tightly and yes it is a insinkerator plug.** A: Sometimes if the plug has been used quite a bit it will shrink a little and the water leaks. I ordered a new plug and it solved my issue. ## Frequently Bought Together - InSinkErator FLG-BIS Disposal Flange, Biscuit - InSinkErator STP-BIS, Biscuit Garbage Disposal, Fits Standard Kitchen Drain Size of 3 1/2 Inch Diameter Sink Stopper - Westbrass D2143P-65 4-3/8" Push-Pull Style Large Kitchen Sink Basket Strainer, Powder Coat Biscuit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/377918678-insinkerator-kitchen-sink-flange-for-insinkerator-garbage-disposal-flg-bis](https://www.desertcart.co.uk/products/377918678-insinkerator-kitchen-sink-flange-for-insinkerator-garbage-disposal-flg-bis) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-28*
