I've searched online and asked locally but it seems that regulations related to water conservation mean getting your hands on a large concealed cistern is hard. I fully understand the water conservation issue but if you need to flush twice then you've used more anyway. Whilst 6 litres does it ok, in this particular installation the drop in the soil pipe before it reaches the stack is not great and for that reason too I'd prefer a larger flush volume. Any ideas? Have been wondering about making one!
