What it is
The Onyx 15mm Electrolytic Scale Reducer is an inline fitting that helps prevent limescale build-up in a home's water system. It works electrolytically, releasing a small trace of zinc into the water that bonds with dissolved calcium ions so they are less likely to form hard scale deposits.
Signs this part needs replacing
- Visible limescale build-up on taps, showerheads or shower screens
- Reduced water flow or pressure over time
- White scale deposits appearing in kettles or on heating elements
- Appliances (kettles, washing machines, boilers) scaling up faster than expected in a hard water area
Before you order
- Confirm the fitting point is 15mm pipework
- Isolate the water supply before installation
- Fit in line with the manufacturer's recommended flow direction and location
