Certificate in Sanitary Plumbing Systems

The Certificate in Sanitary Plumbing Systems is designed to provide learners with practical knowledge and technical skills required for the installation, inspection, testing, maintenance, troubleshooting, and repair of sanitary plumbing systems used in residential, commercial, institutional, hospitality, healthcare, and public buildings.

The program introduces the principles of sanitary drainage and waste systems, including soil and waste pipework, drainage fixtures, traps, vents, cleanouts, floor drains, inspection chambers, manholes, sanitary appliances, and associated fittings. Learners will develop an understanding of how sanitary plumbing systems collect, transport, and safely discharge wastewater while preventing leakage, odours, backflow, and contamination.

The course covers sanitary fixture installation, pipe sizing awareness, drainage gradients, venting, trap seals, pipe supports, jointing methods, testing, flushing, leak detection, blockage prevention, maintenance, and troubleshooting. Emphasis is placed on correct installation, hygiene, drainage performance, accessibility, safe working practices, and compliance with approved project drawings and plumbing requirements.
