Follow up to Post 51911 - Plastic taste in water tanks

Thanks everyone who responded with a variety of "fixs" to removing the taste of plastic from the water tanks.

I tried the idea of the Bicard Soda and found that improved the taste somewhat, however the taste was still there. I then tried that idea a second time and again there was an improvement in the taste, but still a hint of plastic.

I finally purchased a 200g container of Tank Cleen from the local caravan place and followed their instructions and after doing so, I can happily report that the taste of plastic has GONE.

I finally tracked down what had I concider to be the cause of the problem in the first place. About 5 weeks ago, we had been away and I had 2 x 20 litres of water in plastic containers (the type you buy at Big W or camping shops) and I had emptied them into the caravans tanks on the last day before we came home. On return home, I simply refilled my tanks in anticipation of the next trip.

These containers are about 8 years old and had sat in the garage empty for about the last 3 years. On opening them today they have a very strong plastic smell, so my guess is that they have started to break down somehow, probably through lack of use or water stored in them.

Once again, thanks everyone for the help.

Cheers,
