Manufacture the interflush, the biggest water saving device in 150 years. Of the 150 litres we each use a day, 60 are used for toilet flushing. For 160 years we have pressed and let go, releasing the full cistern every time, a complete waste of water. Fit the interflush to the existing siphon and connect to the FRONT handle. Operation is now: press, HOLD DOWN to flush, let go to stop. Uses ONLY what is needed, wasting none at all, saving HALF the flushing water on average, 30 litres per person per day, making all other flushing systems obsolete. £15 in = thousands out over the years. A no brainer. Also SAVES THE SIPHON FROM EXTINCTION, the only flushing device that NEVER leaks. Push-button toilets ALL have DROP-VALVES in the cistern, which have been known to leak for 160 years, 44 litres per person per day, latest figures from US EPA. They are the biggest Trojan horse of water saving ever.
