Is the ES4 Approved in the
UK?
|
|
|
Yes, the ES4 is independently
tested to the latest performance specification
and is one of only a few WRAS approved WCs on
the market.
|
|
Surely 4.5 litres is not
enough to prevent my drains
blocking?
|
|
|
Volume isn't everything! The
hydraulic characteristics of the ES4 pan and
cistern are designed for excellent pan clearance
and drain carry. The new UK WC performance
Specification contains a test for drain carry
and the ES4 passed at only 4 litres. In fact if
you have 'problem drains' we recommend the ES4
which can be supplied to flush with 6 litres.
Laboratory tests aside, the ES4 has been
successfully
used for domestic and commercial installations since 1998.

Why a single flush siphon?
Isn't the siphon old technology?
|
|
|
As water conservation
specialists, it is our belief that the
ES4’s combination of ultra low flush and
leak-free siphon offer the best real-world water
efficiency currently available. Now that the
previously outlawed dual flush WCs is legal, you
could be forgiven for thinking that this would
be the preferred technology for the
environment-conscious buyer. The truth is more
complex; in some trials dual flush WCs have
failed to out-perform 6 litre siphon flush WCs
never mind the 4.5 litres of the ES4. Add to
this the inevitable leakage of valves and the
potential for mechanical failure and you will
see why we favour simple efficiency.
Watch this space for the arrival of the Ifo cera ES4 - duo,
a siphon based dual flush version of the ES4 for domestic
use. Final testing is currently underway.
For a fuller
discussion of the issues, this
article discusses the
pros and cons, with real results from existing
installations. |

Is the ES4 available
close-coupled or low level?
|
|
|
Whilst the modern trend is
towards the clean lines of the concealed cistern
we realise than a close coupled or low level
suite is often easier to retrofit. We are
developing other products but for now the back
to wall and wall hung models are the only
available option.

|
Are other colours
available?
|
|
|
Sorry only timeless and easy
to mix and match white.
|
| But I want a matching bathroom suite! |
