Prevent Hard Water Damage in Your Home
Effective wherever scale prevention is needed. Suitable for installation at the point of use—such as taps or appliances—or at the main water entry point to protect the entire property.
Point-of-Use Scale Protection
Ideal for space-restricted areas where targeted protection is required. Customisable to suit a variety of applications and customer preferences.
Point-of-Entry Limescale Guard
Safeguards the whole building’s water circuit from limescale. Scalemaster Limestop handles multiple flow rates and operates maintenance-free for the duration of the media’s life.
How a Salt-Free System Prevents Limescale
Every bead features natural surface imperfections, known as media templates, which attract minerals like limescale and carbonate. These minerals bond together to create tiny crystals that grow gradually. As the crystals form, they detach and flow through the system without clinging to pipes, fixtures, valves, or heating elements—helping to prevent scale buildup and maintain system efficiency.
Why WRAS Approval Matters for Water Treatment Products
When choosing a water treatment solution, WRAS approval is a key indicator of quality, safety, and compliance. WRAS (Water Regulations Advisory Scheme) certification means the product meets strict UK water supply regulations, ensuring it won’t contaminate the mains water supply. This approval is particularly important for use in commercial kitchens, dental practices, caravans, flats, and motorhomes, where safe and compliant water systems are essential. Choosing a WRAS-approved product not only protects public health but also ensures hassle-free installation and peace of mind for property owners, installers, and regulatory inspectors.
