BTEB Plumbing study guide
BTEB Plumbing · Work through your exam, one topic at a time.
The BTEB Plumbing credential refers to plumbing assessment under the Bangladesh Technical Education Board (BTEB), the government board that administers technical and vocational education in Bangladesh and publishes results, curricula, syllabuses and examination regulations through its official website, bteb.gov.bd. Candidates are typically trainees and students in technical school, vocational, or diploma-level plumbing programmes who need to demonstrate competence in installing, jointing, testing and maintaining water supply and drainage systems to recognised occupational standards. The BTEB Plumbing study guide has 4 sections and about 1,109 words.
01Plumbing Systems and Installation
A plumbing system has two halves that must be designed together: the supply side (service pipe, meter, distribution mains, fixture branches, valves) and the drainage side (fixture drains, branches, soil and waste stacks, vent stacks, building drain, building sewer). Candidates should know the function of the main shutoff, the water meter, the check valve, the pressure-reducing valve, the vacuum breaker, the trap primer, the cleanout, and the vent through roof.
310 words, about 2 min02Pipe Materials, Fittings and Jointing
Candidates must match material to service: copper for potable supply (types K, L, M differ in wall thickness, K heaviest), PEX for flexible supply, PVC and ABS for drainage, cast iron for soil and waste where sound or fire performance matters, galvanized steel for older supply, and CPVC for hot water where permitted. Know the fittings: coupling, elbow (90 and 45), tee, wye, reducer, union, cap, and the difference between a sanitary tee and a vent tee.
278 words, about 1 min03Sanitary Fixtures and Drainage
Know the standard fixtures and their drain and trap sizes: water closet, lavatory, bathtub, shower, floor drain, sink, urinal, and washing machine standpipe. Understand fixture units, trap arm length limits, vent distance from the trap, and the requirement that a trap arm connects to a vent before it drops more than one pipe diameter.
270 words, about 1 min04Plumbing Safety, Codes and Estimating
Safety covers the jobsite and the system: eye and hand protection when cutting and soldering, ventilation when using solvent cement and lead-free solder, fire watch and shielding when soldering near combustibles, safe handling of gas appliances, and confined-space entry rules for pits and vaults. Codes cover permits, inspections, pressure testing (typically hydrostatic at a specified pressure for a specified time), disinfection of potable lines, and protection of the potable supply from contamination.
