The method of supplying water to
an ascending spray and / or hose
and spray bidet is illustrated in
Diagram 3 and which is described
in the formal guidance, is difficult
to achieve in practice. The air gap
should be located above the fully
extended hose and spray, or zone
of backflow risk, and this height
may need to be increased to
provide sufficient water pressure,
to overcome friction loss in the
pipes and fittings, in order to
operate the ascending spray and
hose spray effectively. This method
of supplying blended water to a
bidet involves complicated control
methods as the control of water
to the bidet itself has to be linked
with the control
