Cleaning Water System - Swift Motorhome Owners Service Manual

Cleaning water system

Clean the water system at the start and end of
the season with sterilising fluid.
Sterilising
When cleaning the water system at the start
or the end of the season it is advisable to use
a sterilising fluid e.g. Milton 2, Chempro SDP
or similar.
An explanatory leaflet is available from:
The Milton Food Hygiene Advisory Service,
Whitehall Lane, Egham, Surrey, TW20 9NW
Flush the system thoroughly to remove the
effective fluid traces.
When water is first introduced, or the water
supply in the internal tank, runs out, air will
be present in the pipework. It is important
that every tap is run to remove any air in the
system before, for instance, the shower is
used. Air left in pipework local to a tap can
act as an accumulator and affect the ratio of
hot and cold water flowing from other taps or
shower mixers in the system.
System care
Allowing water to freeze in the system may
result in damage to the pump and plumbing
system.
Non-Toxic antifreeze for potable water may be
used with Truma pumps. Follow manufacturers
recommendations.
Do not use automotive antifreeze to winterize
potable water systems.
These solutions are highly toxic and may
cause serious injury or death if ingested.
Sanitising
The water systems, and in particular storage
tanks, in motorhomes 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 motorhome 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 (e.g. Milton
for 15 minutes).
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.
7. The container should be inverted whilst
stored overnight (if possible).
8. The container must be filled with mains
water only and mains water only should be
used for the above cleaning procedure.
9. On no account should garden hoses be
used to fill water tanks.
For Systems:
1. Drain down the system (open all taps to
allow air in, enabling the system to
drain quickly).
2. Remove any water filters fitted, and replace
with a short length of hose or empty
filter cartridge (this will ensure the filter is
not affected by the disinfectant/ sterilant
solution).
3. Fill the water system with a disinfectant/
sterilant solution (check that the solution at
full strength appears at all taps/showers).
Allow to stand for the recommended period
of time.
4. Drain the system completely.
