WHC Leak-Less Valves aims to solve SA's water problems

How it works

The valve is placed in the toilet cistern and locks at a predetermined level after each flush, prohibiting an excess influx of water and pre-emptively stopping water flow in the instance of a leak. Therefore, it serves as a leak detector as well.

Lesolang’s mission is to retrofit as many applicable toilet cisterns with the WHC Leak-Less Valve and to encourage the industry manufacturers to install the WHC Leak-Less Valve before sale of their toilet cisterns; in new toilets, the WHC Leak-Less Valve serves as a leak detector.

Getting the idea to market

Paseka Lesolang and team

Over the past year, Lesolang teamed up with Resolution Circle to get his idea to market. His winning innovation has recently gone through Resolution Circle’s Idea-to-Barcode product development ecosystem: idea to design, design to prototype, prototype to first production.

Through this process, he consulted with engineers who have refined and streamlined his design into a working prototype. He was also assisted in the application for an international patent. The project went through prototype demonstration with the use of computer-aided design software and rapid prototyping techniques and then moved into small-scale production phase. Resolution Circle manufactured 7000 components for the WHC Leak-Less Valve using injection moulding techniques.

Unemployed workers were then contracted to assemble these components into 1400 units and are ready to save households water in the City of Tshwane.

This Leak-Less Valve solution prevents water wastage, which would effectively contribute to the countries water shortage issues and could save household’s 10% of their monthly water bills.
