6.9 Water System Maintenance.
The water system, and in particular the storage tank is susceptible to contamination by bacteria if
care is not taken with its 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. Even if you boil or filter your water for drinking these symptoms may still
occur.
We advise on board water should not be used for drinking water as maintaining the water system to
the required standard requires regular cleaning before each time the trailer is used. However if you
use the system for non-drinking water it is still important that you carry out the following system
cleaning at least four times a year to keep the system in good condition.
If you wish to use the on board system for drinking water the system must be cleaned as below
before each use and filled using a food grade hose pipe.
6.9.1 Water System Cleaning.
9. Drain the water tank. Use the pump to drain the tank by opening all the taps in the system.
Allow the pump to operate until the tank is empty. Do not operate the pump more than 15
minutes continuously.
If your trailer is fitted with a water tank level gauge the pump will automatically switch off as the
water level reaches empty. To override this feature hold down the pump switch button to keep the
pump running. The pump will stop once you release the button.
10. Using your mains water tank filling hose pipe and a suitable funnel, carefully fill the hose
pipe with a disinfectant/sterilization solution.
11. Connect the solution primed hose pipe to the trailer and mains water and then fully fill the
water tank with mains water.
12. Fully prime the water system so the disinfectant/sterilization solution is in all pipes and
water heater.
13. Allow to stand for the recommended period of time for the solution to work.
14. Drain the system down completely.
15. Thoroughly clean the outside of all taps/connections with a cloth soaked in the
disinfectant/sterilization solution.
16. Flush the system through with clean drinking water until no traces of
disinfectant/sterilization solution can be detected at any tap.
Suitable sterilising chemicals are available from your caravan dealer, accessory shop, chemists or
home-brew shops. It is not, however, recommended to use bleach or sodium metabisulphite
.
6.9.2 Water System Servicing
Replace the water pump filter once a year. Ideally after winterisation period, see 3.2.2.6 Draining
and Winterisation of the Water System.
