Pass Plumbing Level 4 with confidence

Plumbing Level 4: A Practical Study Guide for Kenyan Trainees covers the four new units of the TVET CDACC Plumbing Level 4 course (Cycle 3, greened edition, programme 0732 354 B) and the 320-hour industry training. It is written in plain English for KCSE leavers and Level 3 holders and illustrated with realistic pictures, accurate diagrams and data charts: a whole bungalow from ground tank and roof tank on a steel stand to the county sewer, booster pump sets, rainwater systems with first-flush diverters, gutter patterns, inspection chambers, sight rails and the drain air test, concealed cistern frames, bidets and whirlpool baths.

The Level 3 units (Water Supply System I, Sanitary Appliances Installation I and Drainage System Installation I) are covered in the companion Plumbing Level 3 guide.

RPL candidates — plumbing fundis who already install tanks, gutters and bathrooms and want their skills certified
Trainers who need ready-made explanations, worked examples, practical tasks and record sheets

Why trainees and trainers like it

Follows your curriculum: same units, learning outcomes and hours as the official CDACC Cycle 3 Level 4 curriculum.
Kenyan rules: the National Building Code 2024 air test, storm-water and siting rules, the Ministry of Water demand figures and the Nairobi water tariff.
Safety first: harnesses on stands and roofs, trench support, never entering tanks and manholes, and leaving pump and shower wiring to the electrician.
Real Kenyan costings: quotations for a bungalow supply, a rainwater system, a site drain and an ensuite, and what a leak or a low-flow shower is worth on the water bill.
Independently checked: the technical content, worked examples and answers were checked by an independent plumbing reviewer.
