Frequently asked questions
Here are some common questions about our product.
Blu uses ion exchange technology to reduce the hardness of minerals in your water. As the water passes through the softening resin, these minerals are removed, helping prevent limescale from building up throughout your home.
Blu helps reduce the effects of hard water, including:
Limescale buildup on taps, showers and appliances
Scale buildup inside water using appliances
Soap scum and more difficult cleaning
The effects of hard water on plumbing
Yes. Because it is installed on the incoming mains water supply, all water entering your home passes through the system before being distributed throughout the property.
Blu is designed for families of up to 4 people with everyday water demand. If your household is larger or has higher water demand, such as several people using showers, taps or appliances at the same time, Blu Maxi may be a better option.
The unit is installed directly onto the rising mains water supply entering your property.
Think of the Clack valve as the brain of the water softener. It controls how the system operates, including when it regenerates and how it manages the softening process. Clack is a trusted name in water treatment, helping Blu deliver reliable performance and efficient water softening.
