Aqua-Rex is the name used in the United States for the British Electronic Water Conditioner called Water-King which is designed and manufactured by Lifescience Products Ltd in England
The name "Waterking" is a USA registered trademark for a brand of conventional water softeners so we have adopted the Latin translation Aqua-Rex as the name for Water-King in the USA. All technical details are identical. Aqua-Rex provides the same excellent product range and the same superior customer service in the USA as Water-King does in the UK and the rest of the world
Aqua-Rex is an advanced electronic device that has been used for the treatment of hard water in the UK and the rest of the world since 1993. It is widely used in homes, schools, offices, factories and hotels with many hundreds of thousands installed and successfully working. Aqua-Rex is also the only device of its type to have been scientifically tested to prove that it can deliver partially softened hot water.
