Siliphos Polyphosphate 25kg
R3,036.00
SILIPHOS prevents scale and stops corrosion. It utilizes the phenomenon that minute concentrations of polyphosphates are sufficient to inhibit the deposition of scale onto metallic surfaces. Because of its phosphate and silicate content, SILIPHOS also inhibits corrosion by forming a thin protective layer on the metal surface. A SILIPHOS concentration of 2-3 ppm is sufficient to achieve both of these effects.

Siliphos Polyphosphate Media 25 kg – Scale & Corrosion Protection
The Puritech Siliphos polyphosphate media 25 kg is a specialised water treatment product designed to protect plumbing systems and appliances from scale formation and corrosion. When used in potable water systems, these polyphosphate spheres slowly release tiny amounts of polyphosphate into the water, which helps inhibit mineral deposit build‑up and protects metal surfaces by forming a microscopic protective layer. Water Purification Systems
This product is ideal for residential, commercial, and industrial settings where scale prevention and corrosion control are important for maintaining efficient water flow and prolonging the service life of equipment.
What Is Siliphos Polyphosphate Media?
Siliphos polyphosphate media consists of transparent, food‑grade polyphosphate balls that dissolve slowly into flowing water. As they dissolve, they release polyphosphate and silicate, which help keep hardness minerals and corrosive elements in solution, rather than allowing them to deposit on pipes, boilers, heaters, and other water system components.
This action helps reduce the build‑up of scale and stops the corrosion that can cause brown or rusty water, pinhole leaks, or reduced water pressure.
Key Benefits
- Prevents Scale Build‑Up: Reduces deposits from calcium and magnesium minerals.
- Protects Against Corrosion: Helps form a protective layer on internal metal surfaces, reducing rust and oxidation.
- Improves System Efficiency: Helps maintain water flow and prevents energy loss due to scale on heating elements.
- Low Maintenance: Requires a simple refill every few months, with no electricity or complex installation.
- Safe for Drinking Water: Colourless, tasteless, and safe when used at recommended concentrations (2–3 ppm).

How It Works
When installed in a filter housing or dispenser chamber where water flows through the media, Siliphos polyphosphate slowly dissolves into the water. The released polyphosphates then bind to hardness minerals like calcium and magnesium, keeping them dissolved and helping prevent scale locks on pipe walls and heating elements. At the same time, the silicate component helps form a protective coating on metal surfaces to reduce corrosion.
Importantly, this media does not remove hardness minerals from the water; instead, it prevents them from forming solid deposits, which is different from a softener system.
Where to Use Siliphos Polyphosphate Media
This 25 kg pack is suitable for:
- Residential plumbing systems where scaling causes blocked valves or reduced flow.
- Boilers and water heaters to reduce scaling on heating elements.
- Solar water heating systems that suffer from mineral deposits.
- Commercial water systems in offices, restaurants, or public buildings.
- Pre‑treatment before fine filtration systems, where scale can shorten membrane life.
Installation & Maintenance
To use Siliphos polyphosphate media effectively:
- Install it in a suitable filter housing or cartridge where water flows through the media.
- Monitor water quality and system performance periodically to ensure the media is dissolving properly.
- Replace or refill the media every 3–6 months or when visual depletion is noticeable.
Installation is simple, and no electricity or special tools are required, making it a very low‑maintenance solution for scale and corrosion management.
Comparison with Traditional Scale Prevention
Unlike water softeners, which exchange hardness minerals for sodium or potassium, Siliphos polyphosphate media prevents scale without removing minerals, allowing harmless coexistence of these elements in water while controlling their tendency to form deposits.
Conclusion
The Puritech Siliphos polyphosphate media 25 kg offers an economical and effective way to protect your water system against scale and corrosion. By releasing trace amounts of polyphosphates into flowing water, it supports cleaner pipes, better efficiency, and longer life for water‑using appliances — all with very little maintenance required. For homes, commercial buildings, and industrial systems alike, this media is a smart addition to your water treatment setup.
