To ensure the correct installation of your shower valve,
it is important to fully understand your site installation.
The following information should be investigated prior to
installation.
Is your water system:
 |
High Pressure |
|
Low Pressure |
|
Mains Pressure |
|
Pumped Pressure |
|
Unequal Pressure |
|
Gravity Pressure |
This information is important as not all types
of shower valves suit all types of systems.
Pumps
In some circumstances your showering performance
may benefit from the installation of a pump.
For further information contact your local stockist or a registered
plumber.
General
Advice
Before installation, it is advisable
to fit isolation valves on both hot and cold supplies for
flushing and servicing purposes.
It is important that both supplies are flushed
prior to the connection of mixing valves to ensure no pipe/plumbing
debris enters the mixing valve. A simple method of flushing
is to fit the outlet adaptors to both pipes and secure with
a compression nut and olive, fit the hose to the adaptor and
flush the system out to waste.
The fitting of strainers is recommended in
all installations to prevent debris from contaminating the
system.
Pipe
Position
Before mounting the valve to the wall, the
position for pipework should be decided. There are normally
three inlet positions – top, rear or bottom positions
are possible by rotating the elbows in the valve body. The
availability of this feature should be checked however, as
not all shower valves allow for this.
Exposed
or Concealed?
When purchasing a shower valve it should
be noted as to which type of fitting you require for the installation.
An ‘exposed’ valve is fitted to the surface of
a wall and all pipework is visable (unless the rear pipe fitting
option is chosen, in which case the pipes are fed backwards
into the wall). A ‘concealed’ valve is built into
the wall into a cavity and a concealing plate is fitted around
the valve. The pipework for concealed valves is hidden within
the wall and is not visible. Isolation valves are essential
for a concealed valve to allow for servicing.
