Direct replacement easy to install
Having searched for a direct replacement via the image I had taken of the old unit, this proved to be critical in ensuring I had ordered the correct item. what's even more important is that Roca have replaced the old rubber seal with a more robust silicone type seal that works a treat. I completed the install under 5 minutes, the only thing I forgot to do was to adjust the flush level using the blue float device in the middle of this item, however that's a simple task.

Worked a treat
Replaced a faulty unit that constantly leaked, fitting was easy but be gentle with the plastic bits when you rotate into place

Better out there for the money
As others mentioned, quality of it feels poor but it does work I did find it dripped until the valve itself was tightened so worth checking

Overpriced and engineered but does the trick.
Being the lucky owner of two homes and five toilets I have become used to fixing leaking inlets and outlets. It can be very annoying to have to take a cistern off to replace a leaking flapper valve. If you have an existing Roca valve in your toilet this unit allow you just to use the upper part to replace the faulty unit and is literally a five minute job to insert. However, you can save yourself a lot of money if you just buy the rubber washer on the end of the unit and replace that! Unfortunately for me I cracked the old fixutre when doing my early investigations into the repair and had to shell out for the full unit.

Easy to fit but fragile so be careful
As you can see from the start of my video and old valve had a corroded washer with limescale on it that was causing a small flow of water into the toilet. It was simply a case of turning the water supply off, twisting the old vale about 1cm anti-clockwise and lifting to remove it, then putting the new one on in reverse. You have to be careful not to twist the old and new valves from the top otherwise they may crack. Hold them at the bottom where there are raised notches around the base that help you grip the bottom. I found that rubber gloves helped me grip better. It took about a minute to screw the new one on as it wouldn’t turn clockwise, but don’t force it as it will eventually slip into place. Also there are two models and this one was correct for my two button valve unit from 2005. The other unit is for newer models from a different year. Overall good product and easy to fit.
