## Description

Dual flush valve with threaded rods for easy installation and replacement. Designed for effective water-saving flushing without leaks or maintenance issues.

## Features

- 6/3 LITRE DUAL FLUSH – This Roca dual flush cistern valve offers two flush volumes, for a 6/3 or 4.5/3 litre flush. It is the D2D model from Roca's universal mechanisms, designed for a dual push button with threaded rods.
- PRECISE FIT – Made for the Roca Hall dual flush toilet cistern with bottom inlet (A341620000). A replacement for an old D2D flush valve, with a residual water level of 40 and a 2-inch outlet, ready for screw-in rods.
- COMPATIBLE PUSH BUTTON – The D2D works with screw-in threaded rods. Roca's short dual flush button for D2D and D4D mechanisms (AH0001800R), available separately, connects to this toilet flush mechanism, offering a choice of flush.
- DUAL FLUSH TOILET SYSTEM REPLACEMENT – Replacing the valve takes only a few minutes, using an adjustable spanner and a screwdriver. The manual included with the product explains each step of the installation in detail.
- VALVE SUPPLIED ON ITS OWN – The D2D is supplied on its own; push buttons are not included. With dimensions of 360 x 100 x 100 mm (14.17 x 3.94 x 3.94 in), it is a compact unit designed for a cistern flush replacement in the Roca Hall cistern.
- REPLACEABLE CLOSING SEAL – The closing seal for D1D, D2D and D4D mechanisms (AH0007100R) is available separately from Roca, allowing the seal to be renewed on its own rather than a full toilet flush cistern replacement.

## Questions & Answers

**Q: I purchased this, it is too tall for my toilet. Do you have the shorter version?**
A: Note that the lower section of this unit is detachable. It is the same as the base from which you twisted out the original unit, which should already be fixed into the bottom of your cistern. If you twist off this bottom section of your new unit, you will find that the rest of it fits into the base you probably already have, simply placing it in and twisting anticlockwise. You can keep base the part and its washer and seal as spares, but this is the section that the plumber usually fits to the cistern base on installation.

**Q: Can I use this to replace the old rod version?  One of the rods has snapped so I need new buttons as well..**
A: Push rods and Chrome effect buttons are bought separately I believe. Have you tried making one using a 6 or 8 mm rigid plastic wall raw plug length that you cut to size? It worked for me once and it has lasted for years. Don’t spend >£10 and upwards on direct replacements

**Q: Hi, quick question about the product. Just wondering what size threaded rods does it need for the flusher button on this product? (The two holes on to**
A: The rod's come with the flushing button

**Q: Does this fit the Rosa Laura?**
A: Hi, most likely it wouldn't, but would recommend to get in touch with Roca
