One in-depth article per module of this course, free to read, each ending in a 10-question mock test. They cover the same ground as the lessons, so you can see exactly what the course teaches before you buy it.

• M1 — The Water Regulations: What They Require, Who Enforces Them and When to NotifyThe five things Regulation 3 prohibits, how far the Regulations reach, which work is notifiable and which is not, approved contractors and enforcement.
• M2 — Materials and Fittings Under the Water Regulations: Approval, Suitability and What Corrodes WhatRegulation 4's two tests, what happened to the approval schemes, the five suitability factors, and the corrosion mechanisms that ruin compliant work.
• M3 — Installing Pipework to the Water Regulations: Depth, Ducts, Frost and Contaminated GroundDepth of cover and obstructions, what counts as concealed, how frost protection really works, and permeation through plastics in contaminated ground.
• M4 — Pressure Testing, Flushing and Disinfection: Proving an Installation to the Water RegulationsTest pressure and surge, the rigid and plastics test regimes and why they differ, and the flushing and disinfection sequence paragraph 13 requires.
• M5 — System Design and Valves Under the Water Regulations: Sizing, Isolation and Dead LegsFlow rates and supply arrangements, where stopvalves, servicing valves and drain taps must go, and why capping a redundant branch is not compliance.
• M6 — Cross-Connection and Unwholesome Water: Rainwater, Greywater and Private SuppliesIdentifying non-wholesome fittings, the cross-connection prohibition, why harvested water is fluid category 5, and the air gap mains back-up requires.
• M7 — Fluid Categories 1 to 5: How the Water Regulations Rank Contamination RiskThe five fluid categories, the aesthetic line and the toxicity progression, and the principle that the category follows the use, not the appliance.
• M8 — Backflow Prevention: Arrangements, Devices and What Each One Protects AgainstBackpressure and backsiphonage, paragraph 15, the air gaps and their real category ratings, and the mechanical devices with their ceilings and conditions.
• M9 — Backflow Prevention in Practice: Choosing the Right Protection, Point by PointBaths, showers, bidets, sinks, washing machines, outside taps, irrigation and heating filling loops: the protection each needs and why it changes.
• M10 — Cold Water Services and Storage Cisterns: Lids, Screens, Warning Pipes and CirculationInlet valve closing levels, warning pipes, covers and insect screens, access and clearance, support, and the rules that stop stored water standing.
• M11 — Hot Water Services and Safety Devices: Expansion, Temperature and DischargeThe unvented safety stack, the 60/50/43 temperature regime and where each figure comes from, vent pipes, D1 and D2 discharge sizing, and dead legs.
• M12 — WCs, Urinals and Flushing Devices: Capacity, Overflow and Urinal ControlFlush volumes and the transitional dates, replacement and suite approval, flushing devices, overflows, the backflow position at a WC, and urinal rates.
• M13 — Sanitary Appliances, Water Efficiency and Outside Use: Baths, Taps, Troughs and HosesThe drinking water tap, plugs, the consumption figures — and everything outside the building, where the fluid category jumps to 5 and stays there.
