5. Thoroughly clean the outside of all taps/
connectors with a cloth soaked in the
disinfectant/sterilant.
6. Flush the system through with clean drinking
water until no traces of disinfectant/sterilant
can be detected at any tap.
Suitable sterilising chemicals are available
from your motorhome dealer, accessory
shop, chemist or home-brew shops. It is not,
however, recommended to use bleach or
sodium metabisulphite.
Waste water system
1. The waste water holding tank is secured
underneath the chassis of your motorhome
and is gravity fed.
2. In order to eliminate unpleasant odours as
much as possible, only smooth bore pipes
are used.
However, should the waste water tank be
overfilled, it is possible the waste water will
backfill the drain pipes until it eventually
appears in the shower base. In order to
prevent this, please take note of part 3.
3. The waste water gauge shows the level of
the tank in quarter or half increments, it is
therefore, recommended that the waste
water tank is checked on a daily basis,
emptying when required. This is done by
opening the valve located just beneath the
side skirt on the exterior of the Motorhome
or by turning the handle located inside the
vehicle at floor level behind the rear axle,
usually found in bed box or wardrobe base
(model dependant).
It should be emptied either directly, or via a
waste water container (not supplied) into a
designated waste water area.
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 28psi + / -3psi.
• 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.
