Its textured rubber finish prevents warping, ensuring a reliable, leak-proof flush system. Easy to install with a quarter-turn nut mechanism, this cost-effective replacement part stops water wastage and extends the life of your toilet valve without the need for a full unit replacement. ## Description Roca dual flush valve won't seal properly and is constantly passing water into the toilet pan but there is no sign of an inlet valve failure, it could very well be that the base sealing washer need to be changed. Overtime as the flush valve is opened and closed, small imperfections tend to occur in the surface of the rubber washer causing the washer to be warped and not providing an adequate seal. Review: Work great, saves buying a new unit - Fitting is easy, the nut holing the seal to the unit is not a threaded nut but a quarter turn then pull away, remove old seal, fit new, replace quarter turn nut making sure this lock onto the shaft, great product, great value. Review: cost effective parts to fix the leak - just a bit tricky to detach the old diaphragm from the valve (you have to pull the diaphragm, bayonet and support washer together away from the bottom of the valve) other than that, the overal installation is very simple the leak got fixed as soon as the new diaphragm is replaced, work like a charm ## Features - Suitability Suitable for both Roca old and new style dual flush valves. - Contents Base sealing washer only. - Good quality product ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JKMT0F0 | | Best Sellers Rank | 171,522 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,196 in Washers | | Brand Name | Roca | | Colour | Assorted Color | | Compatible Groove Diameter | 16 Millimeters | | Customer Reviews | 4.5 out of 5 stars 1,563 Reviews | | Exterior Finish | Rubber | | Exterior finish | Rubber | | Fastener Size | 10 millimètres | | Fastener Type | Flat Washer | | Fastener size | 10 millimètres | | Finish Types | Textured | | Global Trade Identification Number | 08433290303100 | | Grade Rating | Good quality | | Included Components | 1 x Roca Dual Flush Valve Base Sealing Washer 822403000 | | Item Dimensions | 18 x 9 x 1 centimetres | | Item Thickness | 1 Millimetres | | Item Type Name | Dual Flush Valve Base Sealing Washer 822403000 | | Item Weight | 0.01 Kilograms | | Item thickness | 1 Millimetres | | Manufacturer | Roca | | Manufacturer Part Number | 822403000 | | Material | Rubber | | Material Type | Rubber | | Metal | Rubber | | Model Number | 822403000 | | Number Of Items | 1 | | Number of Pieces | 1 | | Outside Diameter | 10 Millimetres | | Outside diameter | 10 Millimetres | | Product Warranty | Not applicable. | | Screw Head Style | Flat | | Set Name | Assorted | | Size | 10 mm | | Thread Size | 10 mm | | Unit Count | 1.0 count | | Washer Application | plumbing | | Washer Type | Flat | | Washer type | Flat | ## Product Details - **Exterior finish:** Rubber - **Fastener size:** 10 millimètres - **Material:** Rubber - **Outside diameter:** 10 Millimetres - **Washer type:** Flat ## Images ![Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - Image 1](https://m.media-amazon.com/images/I/41vBtDRY-iL.jpg) ![Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - Image 2](https://m.media-amazon.com/images/I/41XQkNn+N4L.jpg) ![Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - Image 3](https://m.media-amazon.com/images/I/717mtX8ELPL.jpg) ![Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - Image 4](https://m.media-amazon.com/images/I/31Wvx-PKSLL.jpg) ![Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - Image 5](https://m.media-amazon.com/images/I/11WcZnUEX7L.jpg) ## Questions & Answers **Q: How to replace washer and remove existing one** A: Isolate the water inlet (turn off the isolation valve). Flush the cistern. Remove the flush push buttons (press one button fully in to get access to the other button which you can then pull up). Remove the screw and remove the flush button casing (remember the positions of the full/half buttons and the casing so you can put them back as they came out) . Lift off the cistern lid. You will see the flush valve. The valve splits apart about 50mm from the bottom, by turning it anti-clockwise by about 5mm. Remove it and you will see the flush washer held in by a large plastic nut. Undo the nut, change the washer. Replace the plastic nut firmly without using excessive force. Put it all back together in reverse order. When replacing the flush button casing screw, again do not over tighten, just do the screw up until you feel the casing has making contact with the lid. Job done **Q: What is the diameter of this washer, and of the central hole, please?** A: outside diameter 2 5/8 inch hole 5/8 inch **Q: I have a leaking Roca flush but how to determine the model of flush? It looks identical to the picture but dont know if thisis d1 or d2?** A: I believe the difference is to do with the rods in the top which engage with the flush buttons. The D2D has adjustable ones with a screw thread that allow you to change where the buttons sit in relation to the cistern lid. If you remove the buttons you should instantly see if the rods are threaded. **Q: Hi, i have a leaking toilet how do I know if it's just the seal that's failed or I need to order a whole new Roca flush valve?** A: Mine was leaking water in to pan constantly. For a few £’s I changed seal. It worked. If not then order whole part and you’ll have a spare seal. If button is sticking then I’d say a whole new one. Plumber quoted £60. Tip to help keep water out. Wedge a screw driver in to stop it filling up. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work great, saves buying a new unit *by M***L on 28 October 2023* Fitting is easy, the nut holing the seal to the unit is not a threaded nut but a quarter turn then pull away, remove old seal, fit new, replace quarter turn nut making sure this lock onto the shaft, great product, great value. ### ⭐⭐⭐⭐⭐ cost effective parts to fix the leak *by G***T on 16 March 2020* just a bit tricky to detach the old diaphragm from the valve (you have to pull the diaphragm, bayonet and support washer together away from the bottom of the valve) other than that, the overal installation is very simple the leak got fixed as soon as the new diaphragm is replaced, work like a charm ### ⭐⭐⭐⭐ Works well, seems better than the original *by B***J on 18 March 2021* We have several Roca WC's and they have all developed slow leakage due to limescale build up on this washer after 5 or so years use. These more recent washers are translucent as opposed to the original's grey colour and seem to be a softer compound so should work as well or better than the original. ## Frequently Bought Together - Roca Dual Flush Valve D1D D2D Diaphragm Washer Seal AH0007100R, Assorted Color - American Standard 7381042-0070A Flush Valve Seal-RP- - Fluidmaster 400H-002 Performax Universal Toilet Fill Valve High Performance Tank and Bowl Water Control, 1-Pack, Multicolor --- ## 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/48702822-roca-dual-flush-valve-d1d-d2d-diaphragm-washer-seal-ah0007100r](https://www.desertcart.tn/products/48702822-roca-dual-flush-valve-d1d-d2d-diaphragm-washer-seal-ah0007100r) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-16*
