The Roca D1D Dual Flush Cistern Valve is an essential replacement component designed for homeowners and plumbing professionals maintaining Roca toilet systems. It offers a precise, reliable dual-flush mechanism that restores optimal water efficiency to your cistern. While it serves as a high-quality direct replacement, users should verify their specific cistern model compatibility, as it is tailored primarily for the wide range of Roca series such as Dama, Meridian, and Giralda.

It is compatible with a wide range of models including Dama, Meridian, and Giralda, but you should always cross-reference your specific cistern model with the D1D part specification.
Generally, no special tools are required, though a pair of adjustable pliers may be helpful for removing the nut of the old valve.
No, this listing is for the internal cistern valve mechanism. Push buttons are usually sold separately.
With normal household use, the valve is designed for long-term service, though longevity may vary based on water quality and hardness.
It is specifically engineered for Roca systems and may not fit the internal dimensions or mounting holes of other brands.
Check if the base seal of the valve is free from debris or limescale buildup. Ensure the valve is seated correctly.
Verify that the flush cable or button connection is not snagged and that the water level in the cistern reaches the recommended fill line.
Installation of the D1D valve requires basic plumbing knowledge and the isolation of the water supply.
To maintain the valve, avoid using harsh chemical cleaners directly inside the cistern, as these can degrade the rubber gaskets over time. Periodically check for limescale buildup if you live in a hard water area.
