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.

## 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.

The washer was for a Roca dual flush which had a tiny drip inside the tank. I watched a video how to and changed the washer with reasonable ease. Please make sure you clean the outlet base where the washer will sit with a soft cloth.
