16 PLUMBING CONNECTION SUMMER 2015
There’s a general perception that concealed cisterns are
always more costly or complicated than normal cisterns,
although this often isn’t the case. The cost and ease of
installation, in many situations, is likely to be comparable
with what you’d expect with an exposed, close coupled
cistern. Provided the decision to install a concealed cistern
is made prior to the walls going up, it’s relatively straight
forward, as explained by research and development
manager GWA Caroma Dr Steve Cummings.
“When we first brought concealed cisterns over to
Australia we spent a lot of time working out optimum
installation solutions for them. We faced some complexities
because unlike traditional cisterns, they go inside a wall.
With exposed cisterns all you have to do is supply the water
and outlet, connected to the wall or floor.
“There’s a lot of preparation work that needs to come first
from other tradesmen because the framework must go in
before the wall goes up and it has to be done right. It’s so
important to get the installation correct and make sure it’s
trouble-free because major problems can arise with it being
behind the wall.
“We’re also seeing cisterns going into ceilings due to
ease of access. We had to develop special flush pipes using
hydraulic solutions to accommodate those,” Steve says.
There’s also a perception that concealed cisterns will be
more difficult to access and service than normal cisterns
(particularly because they’re embedded inside the wall),
although this concern’s mostly unfounded if your client is
opting for a reputable brand. In most cases, these cisterns
are designed with ease of servicing very much in mind, and
a licensed plumber can typically service a concealed cistern
within minutes, not hours.
Let’s take a look at some of the more reputable options on
the market place.
VIEGA
For Viega’s Mono Slim cisterns there is a wide range of
designer/architectural flush plates. There are no pans in this
range.
“With the Viega Mono Slim cisterns, there is not as much
access to the cistern as plumbers might be used to with
a conventional cistern. However, they will quickly become
familiar with the layout and will find servicing is simple.
Viega’s focus is on providing a slim-line, dual-flush cistern
that’s easy to install and use,” Rod says.
“Ease of installation is a major point of difference. The
mounting plates on the cistern and on the frame enable
simple assembly, plus the water supply connection comes
completely pre-assembled. It means the connection to the
feeder pipe is possible from outside, without opening the
cistern.”
