Winner
of a dti SMART award, the Interflush™ is a retrofit kit,
to convert standard, single flushing WC siphons (no control
over volume flushed) to interruptible flushing siphons
(full control over volume flushed). The patented kit
is designed to be user friendly in its operation, low cost,
easy to install and applicable to the maximum number of different
siphon and cistern designs with front mounted handles.
A siphon stops flushing when air is allowed to enter it. All
the Interflush™ does is introduce an air valve on top
of the siphon which is closed when the flush handle is down,(to
allow flushing) and open when the flush handle is up, (flushing
stoppped).
Thomas Crapper, another Yorkshireman, brought us "press
and let go". The Interflush™ improves on this with
a massive 47% water saving by introducing "press,hold
down and let go" all still in one hand operation.
To operate, simply press, hold down until pan is clear, let
go to stop the flush. Nothing could be simpler.
The Interflush™ is the only device with an adjustable
trailing volume for troublesome drainlines. It gets rid of double
flushing associated with low cistern capacities. With the Interflush™,
the more water in the cistern, the better.
