Water Flow Control System
Help stop water wastage!
In an average home, 10% of
household water usage can be saved automatically, for very
little outlay and with absolutely no ongoing extra power
costs, for the entire lifetime of the dwelling, with the
amazing Enviro Save Water System.
This system, which featured as a
weekly winner and finalist on the ABC’s New Inventors
program, and was named by the show’s host, James O’Loghlin
as his favourite, and most worthwhile invention of the year,
automatically diverts the water which has cooled in the hot
water pipes and sends it back into the cold water line,
rainwater tank, or other storage tank, instead of otherwise
flowing down the drain.

Lloyd's Cool Water-Saving Invention
by Peter Morley
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.
It has won a segment on the ABC's
New Inventors television program, has been described as the
breakthrough of century, and is now in commercial
The $198 valve can be fitted to
plumbing systems in new homes or retro fitted to older style
houses for $475.
Mr 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.
"The tap handle is the trigger
for a process where potable cold water is returned to
Retro fitting was more expensive
because it also required a tank and a pressure-reducing
valve to save the cold water, which was fed back into the
But Mr Linson-Smith said: "When a
three-person house can save 40 litres a day or 16,000 litres
a year it does not take long to get the investment back.
Support for the valve is
increasing, with the Toowoomba City Council announcing a
$200 rebate for everyone who installs Mr Linson-Smith's

Water Flow Control System
( 2005-08-25 )
A water flow control system has a
flow control valve which directs any cool/cold water in a
hot water line to a bypass line when a hot water tap
connected to a water heater is turned on. The bypass line
directs the cold/cool water to a water storage tank for
future supply to a cold water tap and /or other cold water
outlets. When the water in the hot water line reaches the
preset temperature, the flow control valve directs the fot
water to the hot water tap or to a hot water outlet. A
diaphragm valve in the bypass line closes the bypass line
when the hot water tap is closed.
The Enviro Save Water System
automatically saves and enables the reuse of the cool water
which flows from most hot water taps when they are turned
