Sanitář

Eight areas: internal drainage, internal water supply and hot-water preparation, sanitary fixtures, materials and fittings, drawings and calculations, installation/testing/maintenance, occupational safety and hygiene, and standards. Expect a mix of recall questions and short applied problems such as pipe sizing, fall/gradient or pressure reasoning.

Those figures are set by the examining body and change between examination periods, so check the official body's website for the current numbers rather than relying on second-hand information. Plan your pace around whatever is published: roughly a minute per multiple-choice question is a safe working assumption while practising.

The pass mark and the retake rules are published by the official examining body and are not fixed here. Look them up on its site before you register, and note whether a retake requires a waiting period or a new application, because that affects how you schedule your preparation.

Practising installers usually find the practical and materials sections straightforward and lose points on standards, drawing conventions and calculation steps they rarely do on site. The exam rewards precise terminology and correct sequencing, so experience alone is not enough - align your habits with what the standards and documentation require.

Start with internal drainage and water supply, because fixtures, materials and calculations all depend on them. Then take materials and fittings, then sanitary fixtures, then drawings and calculations. Finish with installation, testing and maintenance, safety and hygiene, and standards, revisiting the first two areas at the end.

Common failures: confusing drainage ventilation and trap-seal principles, mixing up which fitting or material suits a given medium or temperature, misreading drawing symbols, forgetting the correct order of operations in a pressure or tightness test, and ignoring safety and hygiene details. Careless reading of negatively worded questions also costs marks.

You need the principles and the requirements far more than a list of numbers: ventilation of drainage, protection against backflow, test procedures, safety distances. Know which standard governs which topic so you can reason to the right answer, and check current editions, since requirements are revised.

Expect some, but at a working level: pipe sizing, slope and fall, flow or volume, pressure relationships, and reading values from a drawing or table. Practise doing them by hand without a spreadsheet, and always check the unit and the direction of the conversion before choosing an answer.
