This episode clears up the single biggest source of confusion in Unit 307 (Level 3 Diploma, and 9289 Phase 2 for apprenticeship / ST0303 apprenticeship learners): the difference between water conditioners, water softeners and drinking water filters, and which one belongs where on a domestic cold water system.
