Two-chamber toilet flushing system

摘要

The first chamber (I) is smaller in volume than the second chamber (II) thus offering both small and large volume flushing. The two chambers are divided by a partition wall and both have separate cisterns with shared water feed but with separate floats and separate shut-off plugs so that they can be used separately. The two plugs are necessarily of different size appropriate to the respective water volumes and enable the chambers to be used individually as required, though both water volumes share a common outlet pipe issuing into the toilet. Two keys are provided at the same level but of different size, using the large key for the large volume and the small for the small volume. The keys can be used separately. One possibility is to use the smaller chamber for cleaning or hygienic purposes, bringing in hot water along a separate line.
