Lesson Overview
Large cold water installations rely on specialised float valves, solenoid valves, and interlinking pipework to maintain turnover, control high mains pressures, and prevent bacterial growth.
Learning Objectives
Compare the operating principles and applications of equilibrium, pressure-operated, and delayed-action float valves against standard BS 1212 fittings.
Apply the regulatory requirements and piping arrangements for interlinking multiple cisterns in series and parallel to avoid stagnation.
Identify the functions of float switches, pressure transducers, and temperature sensors in cold water cistern installations.
