UPMSP High School Plumbing - Code 976 study plan

Select the correct hand tool for ten common tasks (pipe wrench, chain wrench, hacksaw, reamer, die stock, flaring tool, spirit level, try square, chalk line, caulking iron) and state the pre-use safety check and PPE for each.

Measure and mark a 3 m pipe run along a wall using steel tape, spirit level and plumb line, holding line and level within ±1 mm per metre.

Cut 15 mm, 20 mm and 25 mm GI pipe square with a hacksaw, then ream and deburr both ends with a half-round file so the bore is clear and the face is square to the axis.

Thread 15 mm and 20 mm GI pipe with a ratchet die stock, achieving a taper that passes a thread plug gauge, and record thread length and die setting for each size.

Identify the workshop hazards of cutting, threading and grinding (swarf, flying chips, oil on floor) and apply the matching control for each.

Assemble three PVC solvent-cement socket joints (15 mm, 25 mm, 50 mm) using the full sequence: square cut, chamfer, cleaner, even cement coat, immediate insertion and a 30-second hold.

Make one CI soil-pipe caulked joint with tarred gasket rope and lead wool, and state the correct caulking depth and the test pressure the joint must survive.

Join copper tube by capillary soldering on two fittings and by compression fitting on one, explaining flux quantity, heat control and the difference in dismantling.

Bend a 20 mm GI pipe to 90 degrees with dry sand fill and even heating without flattening the bore, then check ovality with calipers.

Describe the HDPE butt-fusion cycle (heater plate temperature, bead size, cooling time) and the compression-fitting alternative for small-bore HDPE.

Reproduce from memory the standard single-line symbols for 20 plumbing fittings, valves and appurtenances, and label them correctly on a blank sheet.

Draft a 1:50 double-line plan of a two-fixture toilet showing pipe sizes, invert levels, gradients and flow-direction arrows.

Sketch an isometric riser diagram for a two-storey supply system showing sump, pump, overhead tank, gate valve, float valve and fixture branches.

Convert one isometric sketch into matching plan and elevation views so that fitting counts agree across all three views.

Calculate daily water demand for a four-person dwelling at 135 lpcd and size both the overhead tank and the underground sump with one day of reserve storage.

Compare direct, indirect and pumped supply layouts and justify a choice for a three-storey building on pressure, continuity and contamination-risk grounds.

Compute total pump head as static lift plus friction loss plus residual pressure for a given building height and pipe run, then select a pump duty point from a simple characteristic curve.

Check a supplied layout against installation and clearance requirements for WC, wash basin, kitchen sink and floor trap, and list every shortfall found.

Explain the operation and servicing of a float valve and a gate valve, including the symptom and fix for a constantly running overhead tank.

Classify one-pipe, two-pipe and single-stack drainage systems and state for each where it is permitted and where it must not be used.

Select the correct trap type and seal depth for WC, wash basin, kitchen sink, floor trap and urinal, and justify each choice.

Size a horizontal drain branch and stack for a given fixture load and set the gradient so the run is self-cleansing without scouring.

Position a gully trap, an inspection chamber and a manhole on a layout, and state the access, cover level and ventilation requirements of each.

Explain stack venting and the cause and cure of gurgling, slow drainage and foul smell in a two-storey house.

Write the step-by-step hydrostatic test procedure for a new supply line, including test pressure, duration, permissible fall and the safety precautions before pressurising.

Write the air or smoke test procedure for a drainage installation and state how each result is interpreted.

Locate five typical leaks (thread joint, solvent joint, soldered joint, caulked joint, fixture seal) and give the correct repair method and tool for each.

Draft a preventive maintenance schedule for a building's tanks, pumps, valves and drains covering frequency, task and record to be kept.

Diagnose eight common complaints from symptom to cause to repair action.

Take off pipe lengths, fittings, valves and fixtures from the week 3 drawing and present quantities in a standard measurement format with units.

Build up a unit rate for one item from material, labour, wastage and overhead, and apply it to the measured quantity.

Apply work measurement to a small job by converting labour constants into man-hours for a stated output.

Prepare a bill of quantities and add wastage and contingency percentages correctly rather than guessing a lump sum.

Compare a prepared estimate against actual market rates and explain each variance.

Answer written workplace-ethics and customer-handling scenarios covering punctuality, quoting honestly, safe disposal of waste and reporting a defect you caused.

Carry out a hazard identification walk of a simulated site and record the control for each hazard found.

Prepare a quotation for a small repair job covering material, labour, transport, overhead and profit margin.

Sit a 90-minute timed mock paper across all eight domains and score it by domain to expose weak areas.

Re-study the two lowest-scoring domains using the error log and re-attempt the missed items.
