Is the official RBSE Secondary (Class 10) Plumbing exam multiple-choice only?

No. Official RBSE papers mix objective and constructed-response tasks and vocational subjects also require practical/skill evidence. The 100 questions here are an English-language MCQ study adaptation for concept practice only.

What are full marks and duration for RBSE Plumbing?

RBSE Class 10 / Praveshika subject schemes in the official syllabus commonly use Theory 80 + Sessional 20 = 100 marks with a 3 hour 15 minute theory paper. Confirm the exact scheme for code 111 in the current RBSE syllabus PDF on rajeduboard.rajasthan.gov.in.

What is the passing score?

Minimum 33% marks in the subject as per RBSE Secondary/Praveshika examination regulations (confirm current session circulars).

Is this bank an official RBSE translation?

No. OpenExamPrep publishes one English-language practice bank per exam ID. Target-language terms and texts may appear when they are integral to the skill, but stems, explanations, and SEO copy are English study adaptations — not official translations or language-environment simulations.

Sample RBSE Sec Voc Plumbing Practice Questions

Try these sample questions to test your RBSE Sec Voc Plumbing exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which plastic pipe is commonly preferred for hot-water distribution lines in residential plumbing because it handles higher temperatures than ordinary uPVC?

A.CPVC pipe

B.Clay sewer pipe

C.Unreinforced concrete pipe

D.Lead pipe

Explanation: CPVC (chlorinated PVC) is formulated for higher service temperatures and is widely used for hot-water supply lines, while ordinary uPVC is mainly for cold water or drainage.

2GI pipe in plumbing practice stands for:

A.Galvanized Iron pipe

B.Glass Insulation pipe

C.Ground Injection pipe

D.General Industrial plastic

Explanation: GI means galvanized iron—steel pipe coated with zinc for corrosion resistance, historically common for water supply.

3Why is zinc coating applied on galvanized iron (GI) pipes?

A.To protect the steel from rust and corrosion

B.To make the pipe magnetic for detection only

C.To increase electrical conductivity for earthing

D.To allow solvent-cement joints like plastic pipe

Explanation: Zinc galvanizing sacrifices preferentially and slows rusting of the underlying steel in water and atmospheric exposure.

4Which fitting changes the direction of a pipeline by 90 degrees?

A.Elbow

B.Coupling

C.Union

D.Nipple

Explanation: An elbow (90° or 45°) changes flow direction; couplings join straight runs, unions allow disconnection, nipples are short male-threaded pieces.

5A reducing tee is used when you need to:

A.Branch a line while changing branch or run size relative to the main

B.Increase pressure without changing diameter

C.Convert a valve into a pump

D.Seal a pipe permanently without any opening

Explanation: A reducing tee has at least one outlet of different size so you can take a branch or continue a run at a different diameter.

6Which valve is best suited when you need either fully open or fully closed service with minimal flow restriction when open?

A.Gate valve

B.Needle valve used as the only house shutoff

C.Check valve used as a manual shutoff

D.Safety relief valve used as daily isolation

Explanation: Gate valves are designed for isolation with a full-bore path when open; they are not ideal for throttling.

7A globe valve is preferred over a gate valve when the main purpose is to:

A.Throttle or regulate flow rate

B.Provide the absolute lowest pressure drop when fully open only

C.Act only as a non-return device

D.Join two plastic pipes with solvent cement

Explanation: Globe valves have a tortuous path that allows better throttling/control; gate valves are better for on/off isolation with lower drop when fully open.

8A check valve (non-return valve) is installed mainly to:

A.Allow flow in one direction and prevent reverse flow

B.Increase water temperature

C.Filter sand from the water continuously

D.Measure flow in litres per minute

Explanation: Check valves open with forward flow and close against reverse flow to protect pumps, tanks, and contamination paths.

9Ball valves are popular in modern plumbing isolation because they:

A.Open and close quickly with a quarter-turn and give a reliable shutoff

B.Must be rotated thirty full turns to open

C.Only work on gas lines and never on water

D.Replace the need for any pipe insulation

Explanation: Quarter-turn ball valves give fast, positive isolation and are widely used on water services.

10Which material is generally NOT acceptable for new potable (drinking) water pipes in modern practice?

A.Lead pipe

B.Copper pipe

C.CPVC pipe

D.HDPE pipe (where approved)

Explanation: Lead can leach toxic metal into drinking water and is obsolete/banned for potable systems; copper, CPVC, and approved HDPE are common potable options.
