Practically every leased unit I've occupied over multiple decades has had a leaky toilet at some point during my occupancy, and none of them were dual-flush models. Had I not corrected them myself or notified the landlord, they would continuously waste water, no big surprise. This is a simple maintenance issue affecting every western flush toilet design I've encountered. I don't understand why a negligent owner/tenant problem is being portrayed as a failure of water-saving flush toilet designs. Are we now expecting plumbing fixtures to disable themselves when in need of simple servicing? Is that the world we want? How about we stop wasting potable fresh water on flushing toilets instead.
