Sample Punjab PSEB Sr. Sec. NSQF Plumbing (Advanced Plumbing Technician) Practice Questions

Try these sample questions to test your Punjab PSEB Sr. Sec. NSQF Plumbing (Advanced Plumbing Technician) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a multi-storey residential building, a cold-water riser should primarily allow the Advanced Plumbing Technician to:
A.Supply successive floors with orderly branch connections and controlled isolation
B.Eliminate the need for any isolation valves on branches
C.Serve only the roof tank with no floor take-offs
D.Replace the entire drainage stack for every fixture group
Explanation: A cold-water riser is the vertical supply main that feeds floor-level branches. Technician design/install practice keeps take-offs orderly and provides isolation so floors or apartments can be shut off without whole-building outage.
2An indirect cold-water system typically stores water in a cistern so that fixtures are fed:
A.Directly from the public main with no storage at all
B.Only by atmospheric pressure from open storage rather than solely live main pressure at every outlet
C.Exclusively by a gas boiler without any pipework
D.Through the soil stack as a dual-purpose pipe
Explanation: Indirect (stored) cold-water systems use a storage cistern; many outlets draw from stored water rather than every outlet being solely on live mains pressure. This buffers supply and can protect the main from back-contamination paths depending on layout.
3When commissioning a newly installed hot- and cold-water system, the Advanced Plumbing Technician should first ensure that:
A.All insulation is painted the same colour as decoration
B.Every joint is buried before any test can be considered
C.The system is flushed, pressurized or charged as specified, checked for leaks, and isolation valves operate correctly
D.Fixtures are used for sewage disposal before water is turned on
Explanation: Commissioning includes flushing debris, pressure/charge testing per method of work, leak inspection, and verifying isolation. Concealing untested joints is poor practice.
4A balanced hot-and-cold supply at a mixer shower mainly requires:
A.Hot water at three times cold pressure with no control
B.Cold water only, because hot is mixed in the drain
C.Open soil-stack connection to equalize shower temperature
D.Reasonably comparable pressures (or thermostatic control designed for the available pressures) so temperature is stable
Explanation: Mixer/thermostatic showers need suitable relative hot and cold pressures (or correct valve type for the duty) so outlet temperature remains stable and scald risk is controlled.
5Zoning a large plumbing system with isolation valves mainly helps the technician to:
A.Shut down only the affected zone for maintenance without isolating the entire building
B.Increase friction loss deliberately on every branch forever
C.Remove the need for any drain-down points
D.Convert potable water into sewage automatically
Explanation: Zone isolation limits outage scope during repair, testing, or renovation. It is a core advanced-system planning skill.
6In a pressurized hot-water cylinder installation (sealed system style awareness), a temperature/pressure relief path is important because:
A.It increases the cylinder volume for storage billing only
B.It provides a safe discharge route if temperature or pressure exceeds design limits
C.It replaces the cold-water main connection entirely
D.It is only decorative and never discharges
Explanation: Advanced systems may include sealed or high-pressure hot-water plant. T&P relief protects against over-temperature/over-pressure by discharging to a safe, visible route—critical safety knowledge for technicians.
7Cross-connection control between potable supply and non-potable uses is mainly intended to:
A.Speed up filling of the soil stack
B.Heat cold water without energy
C.Prevent contaminated water from flowing back into the drinking-water system
D.Eliminate all valves from the building
Explanation: Backflow/cross-connection control protects potable water from contamination by reverse flow from non-potable equipment, irrigation, or process lines.
8A pipework schematic drawing used by an Advanced Plumbing Technician primarily shows:
A.Only the colour of floor tiles in each room
B.The school timetable for theory classes
C.Electrical single-line diagrams of the entire city grid
D.Logical connections of pipes, valves, fixtures, and equipment rather than decorative finishes
Explanation: Schematics communicate hydraulic/logical layout: mains, branches, valves, fixtures, and equipment. They guide install, isolation, and troubleshooting.
9Ring or looped cold-water distribution (where used) can help by:
A.Providing alternative flow paths that can improve supply resilience and reduce single-point bottlenecks when designed correctly
B.Removing the need for any supports on horizontal runs
C.Allowing sewage to circulate in potable pipes
D.Replacing all vertical risers with open channels
Explanation: Looped/ring layouts can feed zones from more than one path, reducing dead ends and improving balance when properly designed and valved.
10Before tying a new branch into a live cold-water main on site, best technician practice is to:
A.Open all fixtures fully and leave them running unsupervised overnight
B.Isolate, depressurize/drain as needed, make the connection cleanly, restore supply, and check for leaks
C.Weld the soil stack into the cold main as a dual pipe
D.Skip isolation because live cutting always improves water quality
Explanation: Safe live-system work uses isolation and controlled depressurization, correct jointing, restoration, and leak checks. Uncontrolled live cutting risks flooding and contamination.
