The tanks and hoses that we supply are all made from food-grade plastic and are non-toxic.

However, there are a number of possible causes of bad taste in the plumbing.

These generally relate to storage and installation issues.

Common causes of bad taste:

* If silicone has been used anywhere to connect the tank/hose and is exposed to water flow this will be the taste.

* If tank clean has been used and exposed to the silicone a reaction occurs which will also leave a bad taste in the plumbing

* If non-food grade plumbing is used it can also lead to poor taste.

* Sometimes prolonged storage can lead to bacteria build-up

There are a number of methods suggested to try and reduce the bad taste.

Ways to clean your tank:

* Using tank clean to flush out the tanks

* Flushing the tanks with red cordial (yes that is right the drink) Fill the tank and let it rest overnight before flushing

* Flushing tanks - with Milton or bicarb

* Replacing non-food grade fixtures and fittings and removing any silicone that is coming in contact with the water

Ways to avoid it happening:

* Avoid air getting into tanks and keep them full when the van is not in use

* Whenever possible fill your tanks with clean chlorinated fresh water.

* Use a filter to clean all particles out of the water before filling the tanks

* Avoid light which can help bacteria breed. Use black plastic tanks and dark pipes. Avoid clear plastic pipes.
