Tainted Water from Plastic Water Tanks

 Put about 20 litres of water in the tank with half a packet of bicarbonate of soda and go for a drive (eg. the first day of your trip).

Drain and refill with fresh water.  Works a treat!

Always make sure you are using fittings and hoses rated for drinking water otherwise nothing will improve the taste.

 Note:  All this assumes that drink safe hoses/connections are used and that they are black (i.e. no light can get into the system to allow algae to grow)
