Water pump pressure switch
The purpose of a pressure switch is to monitor
the pressure on the outlet side of the pump.
When a tap is closed, and the pump continues
to run, there is an increase of pressure in the
system, and when that pressure reaches a
pre-set limit, the pressure switch will turn the
pump off.

pump. (Normally Grey upper section with
White lower section/valve housing)
• All of the Truma/Flo-Jet pumps used by Swift
are pre-set at 25psi - 31psi.
• To further adjust the pressure switch setting,
a cover cap must be first be removed from
the end of the pump to reveal a pressure
adjusting screw, as shown in the photos.
A maximum of 1/4 turn clockwise or
anti-clockwise, from the factory setting, is
advised. Turning the screw clockwise 1/4
turn will increase the pressure switch cut-out
pressure, turning the screw anti-clockwise
will reduce the pressure setting.
• Please note a second screw mounted
below the cover cap is set in position with
threadlock, this should not be disturbed.

Sanitising
Guidance on cleaning portable water
tanks and the water system in touring
caravans.
The water systems, and in particular water
tanks, in caravans are susceptible to
contamination by bacteria if care is not taken
with their use and cleaning. The symptoms
caused by bacterial contamination are not
purely limited to gastro-intestinal diseases,
but may also manifest themselves as ear,
nose, throat, eye or skin infections. It is
therefore important that you carry out the
following procedure prior to using the caravan
each time, even if you boil or filter all water you
use for drinking.
Separate Water Containers
1. All water remaining in the container
should be disposed of so that the container
is empty.
2. The outside of the container should be
thoroughly cleansed and washed down to
remove any dirt, dust or other contaminant.
Water at a suitably hot temperature
containing an appropriate detergent is
recommended for this purpose.
3. Water should be put in the container, swirled
around, then emptied out.
4. The container should then be totally filled
with water containing an appropriate
sterilant solution and allowed to stand for
the recommended contact time.
5. The solution should be emptied from
the container.
6. The opening of the container should be
cleaned thoroughly with an appropriate
prepared wipe impregnated with a sterilant.
