Toilets designed to save water are actually wasting it at an alarming rate, says the U.K.'s largest water utility. Dual-flush toilets have separate buttons for heavy or light flushes with the goal of reducing the overall mount of water used. That means some 400 million litres of water leak from U.K. toilets ever day — enough to supply 2.8 million people. Dual-flush toilets usually have a mechanical valve with a rubber seal in the cistern that opens to allow water to flow when flushed. "If we can if we can crack this issue, then the dual-flush toilet really has a bright future," he said.
