Review: Great product, replaced old model perfectly. Poor delivery person - The product is the updated version of the old green one I had. I replaced it because water was streaming into the bowl constantly. I just took out the removable part and slotted in the replacement part and hey presto, the leak had stopped. A lot cheaper than getting a plumber out who would probably have charged £100 and £50 for the item. The delivery person marked the item as handed to resident, which was a lie. They didn't ring the doorbell at all and just left it on the front step by the street. We have a safe space to leave items if they can't be bothered to try and actually get someone to answer the door to take it. Great product, poor delivery. Review: Complete flush unit and a simple valve swap. - This is the complete fitting. I only needed the valve so a simple 5 minute swap with the existing valve. This kit is bit £70 from bathroom shops so a total bargain. Good packaging too. Highly recommended if you have a compatible flush unit. ## Features - Geberit Impuls 250 Dual Flush Valve For Two-piece Toilet Tanks.The overflow pipe can be adjusted in height according to the water level - Replacement Geberit Impuls 250 Dual Flush Valve - Geberit Impuls 250 includes the support bridge button.The button lever is hidden inside the overflow pipe - Outlet size 2 inches.The outlet is connected by a threaded nut - Geberit Typ 250 Dual Flush Valve Replacement For Toilet Cistern Outlet Valve ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0842KKPTP | | Best Sellers Rank | 10,386 in DIY & Tools ( See Top 100 in DIY & Tools ) 27 in Toilet Parts | | Brand | GEBERIT | | Connector Type | nut | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 765 Reviews | | Exterior Finish | Plastic | | Exterior finish | Plastic | | Included Components | Flush Valve,Flush Valve Button,Valve Support,Valve Bottom connection,Link nut | | Inlet Connection Size | 38 Millimeters | | Inlet Connection Type | Compression | | Inlet connection size | 38 Millimeters | | Inlet connection type | Compression | | Item Dimensions | 12 x 8.2 x 31 centimetres | | Item dimensions L x W x H | 12 x 8.2 x 31 centimetres | | Manufacturer | GEBERIT | | Material | Plastic | | Model Number | 250 | | Number of Pieces | 1 | | Number of Ports | 1 | | Outlet Connection Type | BSPT | | Part Number | 250 | | Size | 8.2 x 12 x 31 cm | | Specification Met | CE, WaterSense | | Thread Size | 2 inches | | UPC | 077063686724 | | Unit Count | 1.0 count | | Valve Type | Flush Valve | ## Product Details - **Brand:** GEBERIT - **Exterior finish:** Plastic - **Inlet connection size:** 38 Millimeters - **Inlet connection type:** Compression - **Item dimensions L x W x H:** 12 x 8.2 x 31 centimetres - **Material:** Plastic - **Number of Packs:** 1 - **Number of ports:** 1 - **Outlet connection type:** BSPT - **Unit count:** 1.0 count ## Images ![Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Image 1](https://m.media-amazon.com/images/I/61ZpnfWOYpL.jpg) ![Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Image 2](https://m.media-amazon.com/images/I/61ls0SIJJAL.jpg) ![Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Image 3](https://m.media-amazon.com/images/I/71hr-wwJ4ML.jpg) ![Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Image 4](https://m.media-amazon.com/images/I/51j1-kNqLQL.jpg) ![Geberit Impuls 250 Twico 1 Dual Flush Valve Toilet Cistern Outlet Valve Replacement - Image 5](https://m.media-amazon.com/images/I/71RAII7v7tL.jpg) ## Questions & Answers **Q: Hello i was told to buy part no. 223.830.21.1 /3 is it same what you are selling? will it fit my rak toilet cistern valve?** A: Dear buyer. 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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, replaced old model perfectly.
