Not 223.830.21.1 /3. But you can determine whether it is suitable or not based on the size in the picture? Thanks! **Q: Hello will this dual flush work for an ideal standard kyomi toilet cistern. thanks.** A: It will dual flush, but you will have to fit the supplied push buttons into the cistern lid **Q: How do I remove previous one and replace with this One they are exact replica I tried twisting previous one but it won’t move will appreciate help** A: With a close couple cistern, you will need to remove the cistern from the base or pan. With it removed you can access the large plastic nut underneath which holds the component in place. Obviously, before you start you need to isolate the water supply to the toilet, then flush it to remove most of the water from the cistern. You can then use a sponge to mop up the rest before dismantling. If you’re still unsure, there’s tutorials on U Tube that you can follow. It’s not as big a job as it sounds. Good luck! **Q: Is there 1.5" outlet base or could you recommend a compatible product?** A: Dear buyer.I'm sorry.We don't have 1.5". We only have a standard outlet of 2".Thank you very much! ## Frequently Bought Together - Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Geberit Impuls 250 Twico 1 Original Dual Button Flush Valve Toliet Push Button - Geberit 816.418.00.1 Flush Valve Base Sealing Washer - Clear --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/188058310-impuls-250-twico-1-dual-flush-valve-toilet-cistern-outlet](https://www.desertcart.tn/products/188058310-impuls-250-twico-1-dual-flush-valve-toilet-cistern-outlet) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-31*
