  • Review installation diagram: Compare actual plumbing to the Cillit installation schematic to identify mis‑connections.
  • Identify hard water requirement: Determine which outlets should receive untreated water (e.g., kitchen drinking tap, outside tap).
  • Re‑pipe as needed: Install a hard water branch before the softener inlet to feed the required outlets, or adjust the bypass manifold if designed for mixed supply.
