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 4. Drain the system completely.

For Systems:
1. Drain down the system (open all taps to
allow air in, enabling the system to
drain quickly).
2. R emove 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. F ill 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.
5. T horoughly clean the outside of all taps/

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.
Do not use products that contain aggressive
agents for sterlising the water system. Always
use products designed for stainless steel tanks
available from your motorhome dealer.

when disinfectant/sterilising fluid is present.
Doing so may damage the system.
