My Sports Water Bottle

Many users of sports water bottles have asked us why their tap water appears white.

The appearance of a white milky colour in tap water is usually air bubbles coming out of solution of the water. 

When cold water (as is found in most taps) heats up to room temperature, it is unable to hold as much gas, and as it comes out of solution makes a white colour.

If you still want to be sure that it is air that is in the water, fill a clean glass with tap water and place it on a table. 

If the white colour clears from the bottom and moves upwards, it is just the air moving out of the solution.

If on the other hand, it remains milky for a long period of time, or dissolves through the whole system, it would be advised to have your water checked. If the white colour clears from the top and moves down, it could indicate hardness salts in your water.

It’s important to ensure that the water you drink on a daily basis and in your sports water bottles is coming from a clear source.
