Hi Ya All! I unfortunately put about 5 litres of diesel
into one of my water tanks
(fibreglass tanks) 3 years ago and went on line for advice
. the best advice
was to super chlorinate the contaminated tank, flush it out, refill the tank and repeat the chlorination process, flush it our, refill and flush it out without the chlorine then if possible scrub it out with dishwashing detergent.
Luckily I have large inspection ports
and was able to lay oil
absorbent mat on the top of the water
before I began the chlorination process and that absorbed most of the diesel
floating on top of the water, after I'd cleaned out the tank (one of two 600lt tanks) , the water was as sweet as ever and remains so to this day.
