FAQs
Is this valve compatible with Roca Khroma?
Yes. Part A822023100 is the Roca D3D dual-flush drop valve specified for Khroma concealed cisterns. Match the part code before ordering.
Does this include the button and cables?
No. This listing is for the valve only. The Khroma button-and-cable set (e.g. A822034101) is supplied separately.
What flush volumes does it support?
It’s a dual-flush mechanism typically set up for 6/3 L or similar, depending on your cistern/pan configuration.
My toilet trickles after flushing — will this fix it?
Often, yes — wear on the valve seal can cause water to continue to trickle into the pan after a flush. Inspect the seal and replace the valve or seal as needed. Also ensure the fill-valve level isn’t set too high.
How do I confirm I have the D3D valve?
Isolate the water, remove the cistern lid and visually check the valve body/base profile. Many units have a label or moulding referencing D3D or the part code.
Is it suitable for residential and light-commercial use?
Yes — Khroma installations commonly use this valve in both domestic and light-commercial settings, assuming the cistern is specified for it.
What should I replace at the same time?
Consider refreshing the button/cables if action feels stiff, and check any base/outlet seals while the cistern is open.
