When chasing in blockwork, what is the maximum depth that is permitted for horizontal chases?
1/4 of the wall thickness
1/8 of the wall thickness
1/6 of the wall thickness
1/3 of the wall thickness
Which of the following is a false advantage of bending copper piper rather than using fittings?
There is less frictional restriction for the flow of water
It is less costly
Long sections of pipework can be prefabricated at once
You must hold a hot works permit in order to bend pipework
Low Carbon Steel is made from:
99.85% iron and 0.15% carbon
90.9% iron and 9.1% copper
95.55% iron and 4.45% steel
50.5% iron and 50.5% carbon
The image shown here is referred to as?

Dezincification
The colour used to identify medium grade Low Carbon Steel pipework is?
Red
Yellow
Blue
Brown
Press fit type fittings can be identified by which of the following description?
A copper made fitting, also be identified as 'endex'
A copper made fitting with a deposit of solder manufactured into the fitting
A copper made fitting with rubber o-ring compressed onto the pipe to create a water tight seal
A brass made fitting, the water tight seal is kept by a means of a nut and olive
Identify: Spring toggle fixing
The required distance between the centres of two equal tee fittings on a copper pipe is 600 mm. The 'X' dimension (centre of tee to end of pipe) of the tee fittings is 10 mm. The length of pipe required for an accurate measurement is:
620mm
600mm
590mm
580mm
To calculate how much LCS pipe is required you will need to work out the centre-to-centre measurements, how is the achieved?
Working out the length of pipes, minusing for the X-dimensions
Working out the length of pipes, minusing for the Y-dimensions
Working out the length of pipes, minusing for the Z-dimensions
Select the correct image: Drain valve.
Which of the following copper grades would this tool be used to bend?
R220 soft coiled
R220 annealed coil
R250 half hard
R290 hard lined
Low carbon steel is identified as the red caps meaning grade-heavy, but what is the heavy LCS pipe used for?
Steam and fire systems
Heating
Oil lines
Gas
Which of the following is not a correct jointing compound used on LCS pipework?
PTFE tape
Hemp and paste
Gaskets
Solder
Which of the following is not regarded as a reason for clipping distances?
To limit the amount of sagging in the pipework
Smaller diameters needing more support due to being weaker
Differentiation of forces from vertical to horizontal
BS1212 states the sizes as the minimum requirement to pass inspections
Which one of the following parts of the Building Regulations deals with building structure?
Part A
Part B
Part F
Part L
The tool set shown in this image is used for cutting which type of material?
Masonry/brickwork
Plastics and wood
Asbestos
The image shown here is used for what purpose?
Used to protect where pipework is in vulnerable positions
Used as an electrical conductor where there may have not been sufficient earthing
Used to bend the pipework without the diameter being damaged
To calculate how much copper pipe is required you will need to work out the centre-to-centre measurements, how is the achieved?
Working out the length of pipes, minusing for the X-dimensions
