Sample Haryana BSEH Senior Secondary NSQF Plumbing Practice Questions

Try these sample questions to review concepts for the Haryana BSEH Senior Secondary NSQF Plumbing exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a sensor plumbing fixture, what is the primary role of an infrared (IR) proximity sensor?
A.To heat water to a set temperature
B.To detect a user’s hands or body and trigger flow without touch
C.To measure pipe wall thickness during installation
D.To convert AC mains power into solar energy
Explanation: IR proximity sensors detect reflected infrared energy from a user’s hands or body and send a signal that opens the water path, enabling touch-free operation of faucets, urinals, and similar fixtures.
2Which component in a typical battery-powered sensor faucet actually opens and closes the water path when the control board commands it?
A.Solenoid valve
B.Spirit level
C.Die stock
D.Plumb bob
Explanation: A solenoid valve uses an electromagnetic coil to lift or drop a plunger, opening or closing the water path when the sensor control board energizes it.
3Why do many wall-mounted sensor faucets use a separate battery box rather than only internal cells inside the spout body?
A.To make batteries impossible to replace
B.To allow easier access for battery inspection and replacement without dismantling the spout
C.To heat the cold-water supply
D.To serve as the only sewer trap for the basin
Explanation: A remote or under-deck battery box keeps batteries accessible for routine replacement and keeps electronics dry and serviceable without fully dismantling the spout assembly.
4Before installing a new battery pack in a sensor faucet battery box, the plumber should first:
A.Open the main building sewer manhole
B.Isolate power if required, open the box carefully, note polarity, and fit the correct type of cells
C.Apply solvent cement to the battery terminals
D.Remove the house water meter permanently
Explanation: Safe battery replacement requires correct cell type, correct polarity, dry contacts, and secure reassembly of the battery box so the control circuit receives reliable DC power.
5Which statement best describes a deck-mounted sensor faucet compared with a wall-mounted sensor faucet?
A.Deck-mounted units fix through the basin or counter; wall-mounted units fix to the wall above the basin
B.Deck-mounted units never need water supply connections
C.Wall-mounted units can only be operated with a foot pedal
D.Both types always use city gas as the power source
Explanation: Deck-mounted sensor faucets install through the counter or basin deck, while wall-mounted models fix to the finished wall; both still need supply connections and sensor power.
6A major hygiene advantage of sensor faucets in public washrooms is that they:
A.Eliminate the need for any water supply
B.Reduce hand contact with handles, lowering cross-contamination risk
C.Replace the need for soap completely
D.Convert waste water into drinking water automatically
Explanation: Touch-free activation avoids shared metal handles, which helps reduce transfer of germs between users in high-traffic washrooms.
7During IR sensor faucet installation, the sensing window should generally face:
A.Into a permanently dark, sealed box with no user approach path
B.The area where hands or the user will naturally approach the spout
C.Directly into a bright solar reflector only
D.The floor trap outlet only
Explanation: The IR window must “see” the user’s hands or body in the normal approach zone so detection and automatic flow work reliably.
8Which of the following is a typical water-saving feature of a well-adjusted sensor urinal?
A.Continuous flush for 24 hours regardless of use
B.Flush only after a user is detected and then leaves the sensing zone
C.Flush only when the city gas meter turns
D.No trap seal water allowed in the fixture
Explanation: Sensor urinals usually trigger a timed flush after occupancy detection ends, flushing only when needed and reducing wasted water compared with continuous flow.
9In a sensor-operated cistern system, the sensor signal primarily controls:
A.The color of ceramic glaze on the WC pan
B.An electronic flush valve or solenoid that releases cistern water
C.The structural load rating of the floor slab
D.The brand stamp on the manhole cover
Explanation: The sensor board commands a solenoid or electronic flush valve so cistern water discharges for a controlled flush without a manual handle.
10A common power source for standalone sensor shower valves in renovations without nearby low-voltage wiring is:
A.Dry-cell or battery pack powering the control module
B.Open flame from a LPG torch
C.Compressed air only with no electronics
D.Municipal sewage pressure alone
Explanation: Many sensor showers use batteries or a battery pack for the control board and solenoid where dedicated low-voltage wiring is not available.
