7.1 Water system - Introduction
All Swift Group motorhome water systems
have been designed around a pump fitted
within the motorhome. This pump draws water
from an under floor or internal water tank,
to provide water pressure within the water
system, whenever it is switched on and water is
available.
The schematic below shows the basic
configuration of the water system:

MOTORHOME WITH FITTED
FRESH WATER TANK
When power is supplied to the pump, it will draw
water from the water tank, and pump it to the
motorhome taps, shower and water heater.
The pump is fitted with its own pressure switch,
and will continue to pump water, until the
pressure of water on the output of the pump
reaches a pre-set level. For this pressure to be
achieved, the taps must be closed.
When the taps are opened, water will leave the
tap via the spout, and the pressure in the pipes
between the pump and the taps will reduce.
Because of this reduction in pressure, the
pressure switch on the pump will switch back
on and the pump will again run to pump more
water.
Close to the pump, the water under pressure is
split into two paths:
1. Through blue water pipes routed directly to
the cold connection of each tap.
2. To the water heater.
Water from the pump enters the bottom of the
water heater. Once the water fills the water
heater (typically 8 litres), water then leaves the
water heater via a connection at the top of that
water heater. This water, which is still under
pressure, then routes to the hot connection of
each tap via the red pipes.
To winterise the system please see separate
details later in this handbook.
7.2 Fresh water system
All fittings, including the holding tank, water
pipes, taps and connections are of food quality
material (to BS6920) and therefore, should
not affect the quality of the water used. It is
recommended however, that the system is
flushed through twice before it is used for the
first time, and always cleaned/flushed after it
has stood unused for a period of time (eg over
the winter period). Care has been taken (using
smooth bore pipes etc) to eliminate as many
water traps as possible.
When filling the fresh water system remember
to check that the water source is suitable for use
as drinking water. If possible avoid using water
sources which use desalination or other similar
processing, as they may contain chemicals that
could damage the stainless steel components
within your motorhome water system. If in
doubt, check locally before using a water supply.
The fresh water system is fitted with an
electrically operated drain valve, which will
drain the contents of the fresh water tank. The
valve is controlled using a switch located in an
upper locker, within the motorhome.
