Plastic water tanks used in caravans are made from Food Grade Plastic (usually polyethylene). They are capable of storing water for long periods of time. If your water just doesn't taste right there could be a number of problems, from mould or algae built up in the tank, to chemical transfer from incorrect hose choice or just high levels of minerals in the water.
There are many ways of combating this but they all have their down sides. Bottled water is expensive, additives can be time consuming and complicated, and filler filters are wasted on filtering all your water rather than just what you drink. You can tackle these problems one at a time but it can be frustrating when you do not get the desired result.

How to clean your tank
If your water has a bad taste and you have isolated the problem down to the tank and piping then it is a good idea to give the whole system a flush. A good low-tech method is to add about 1/2 cup bi-carb soda to your half full water tank and then add some vinegar and take the van for a bumpy ride. This produces a chemical reaction creating a bubbling effect, which is great for dislodging any built up sediment and biofilm in your tank.
Note: Make sure you turn off you water pump and turn tap on to allow any pressure to be released.
Some other common alternatives are:
Miltons (baby bottle sterilliser) from supermarket.
Sanitiser from Home Brew shop.
All products must be diluted then the tank flushed with clean water.
Below are some products we sell.
How to the get plastic taste out of water tanks
Another common source of introducing impurities and a bad taste to your tank is the filling hose. General garden hoses are not food grade and the constant exposure to sunlight degrades them.
The slight transfer of chemicals from your plastic tank and pipes is very common and hard to avoid. This is not dangerous as long as you have food grade plastic. The plastic taste is the only issue, it is most noticed on new tanks or if the water has been sitting for a while in the heat.
Another low-tech method to fix to this - red cordial. Thats right, red cordial! (green might work too, I have always used red).
Simply go buy the cheapest one you can find pour the whole bottle into tank and fill up. Run your tap till red cordial comes out then allow it to sit over night. The next day, drain the tank and flush. Job done.
Some people also add lemon juice or a water freshener. A commercial option is shown below.
Prevention - its better than a cure.
Mould and algae can grow in your water tank under certain situations. It is important to minimise light and air contact with your water. Most plastic tanks are dark in colour, you should also avoid using clear tubing on your filling, breather and outlet pipes. Black food grade tubing is best.
To minimise contact with air you should fill the tank completely when storing. A dry tank is also good but is harder to achieve as the outlets on most tanks are raised slightly from the bottom. Another cause of algae is storing impure water.
Sometimes it is necessary to fill your tanks from a river or other dubious source. The products below will treat your water (and help avoid an upset tummy) as well as reduce algae development.
If you are using non-chlorinated water then it is recommended to flush your tank and lines before storage.
