Sterilising the water system
There are a number of ways of sterilising your vans water system, the most popular method appears to be by using Milton. However, this taints the water and you have to fully flush the system 2 or 3 times to remove the taste. There is now a product, Citoxx Bio, which can be used to sterilize the complete water system, including in-line filters, that leaves no taste or odours and does not taint the water. Citroxx Bio was developed in the UK 10 years ago and is used in third world countries for purifying drinking water as well as other diverse applications.
