I have drained and opened the tank of my 24 year old narrowboat because of a large amount of rust silt in the water. I would like to know if there is any form of water tank paint that enables the water to be potable....drinkable. So far I have found bitumastic paints that say they are for "Non Potable" water tanks. Thank you in anticipation. Regards Rupert

Googling "Potable tank paint" throws up a number, many not bitumen, however have a look at these http://www.diysupermarket.com/bond-it-bitubond-b itumen-paint.html http://www.ukroofingsupplies.co.uk/waterproofing /64-allweather-aluminium-roof-compound.html. Often they say non-potable to save them paying to have the product tested. Tony Brooks
