Cool Water-Saving Invention Runs Hot
A Darling Downs resident has invented a valve that stops the average household losing 16,000 litres of water down the drain.
Lloyd Linson-Smith’s Enviro Save device diverts and saves cold water that flows from domestic taps before hot water arrives.
The $198 valve can be fitted to plumbing systems in new homes or retro fitted to older style houses for $475.
Linson-Smith, 77, got the idea after he moved from Brisbane to Oakey, where his new home was supplied by tanks.
“We used to save the cold water in buckets for use in the garden but then my wife said, ‘Okay smart arse, you have spent a lifetime as a tool and light machinery manufacturer so you should be able find an easier way to save our precious water’,” he said.
“So I came up with the idea of a brass valve that is installed in the hot water pipeline just before the kitchen sink,” he said.
“The cold water ahead of the arrival of the hot water is identified by a thermal element and bypasses the sink.

I don’t think Mr Linson-Smith came up with this idea at all. I am sure that he came up with the idea of making a valve to do this after he saw the first model of the Redwater Diverter – the technology that underpins these valves. He had a system that he went on the New Inventors with – a whole series of valves and tanks – from what I can tell the same as what “Powers” had in the United States in the 1990′s. He offered to buy the valves from Redwater Australia once he realised that the technology he had copied from Powers was now limited. He then offered to licence the rights from Redwater Australia. So in short – if you want to see the product that started it all http://www.redwater.net.au
