9289 Phase 1 - 302 (Pipework Joints Activity 4)

What are the benefits of forming pipework correctly during installation?

• The installation looks good, water flows correctly, and the pipe can be supported sufficiently

• The installation will be faster but less reliable

• The pipe will be more expensive

• The water will flow slower

Consider a scenario where pipework is not formed correctly. What potential issues might arise in the plumbing system? (DoK Level 3)

• The installation may look unprofessional, water flow may be disrupted, and pipes may lack sufficient support

• The pipes will become more flexible

• The water will become cleaner

• The installation will be easier to repair

When using a tube bender, where should you place the 4D mark?

• On the ‘start of bend’ mark on the benders.

• On the end of the tube.

• On the fixed point.

• On the set square.

What is the purpose of measuring back four diameters of the tube size before bending?

• To ensure the bend starts at the correct position for an accurate 90° angle.

• To make the tube longer.

• To mark the end of the tube.

• To check the tube for defects.

What is the offset measurement given in the example for a copper pipe offset bend?

• 25mm

• 100mm

• 50mm

• 75mm

When measuring for a copper pipe offset bend, what should be deducted from the 600mm folding rule?

• The pipe diameter

• The size of the offset

• The pipe length

• The angle of the bend

What is the purpose of repositioning the rule when creating a copper pipe offset bend?

• To give the correct angle for the second bend.

• To measure the length of the pipe.

• To check the thickness of the pipe.

• To mark the cutting point on the pipe.

If the diameter of the obstruction is 40 mm, what value should be added to the measurement from the fixed point to the centre of the obstruction to determine the bench mark for the first bend?

• 10 mm

• 20 mm

• 30 mm

• 40 mm

After determining the correct angle for the first bend, how should the tube be positioned in the bender?

• So that the bend mark and the centre of the angle align.

• So that the end of the tube is at the centre of the bender.

• So that the tube is perpendicular to the folding rule.

• So that the tube is parallel to the folding rule.

What is the purpose of placing a straight edge over the tube when making a copper pipe passover bend?

• To ensure the pipe is cut to the correct length

• To mark the bending points on both sides of the obstruction

• To check the thickness of the pipe

• To measure the diameter of the pipe
