Sanitary Appliances and Pipework Systems phase 2 1.6

What is the expansion rate of PVCu soil pipes and waste pipes?

• 0.06cm/m/C

• 0.06mm/m/oC

• 0.06cm/m/oC

• 0.06mm/m/C

What can happen if the expansion of PVCu pipes is not accommodated for?

• Increased water pressure

• Corrosion of the pipes

• Decreased water flow

• Pipe movement and joint leakage

In the given example, how much will the 6m run of 110mm soil pipe expand?

• 0.072mm

• 7.2mm

• 0.72mm

• 72mm

How much expansion should be allowed for in pipe fittings to prevent joint leakage?

• 0.1mm

• 10mm

• 100mm

• 1mm

In the given example, how much will the 15m run of 110mm soil pipe expand?

• 3.15mm

• 31.5mm

• 315mm

• 0.315mm

Where is the 15m run of 110mm soil pipe to be fixed?

• Vertically inside a residential building

• Horizontally in an industrial building

• Horizontally in a small commercial property

• Vertically on the outside of a multi-storey building

What is the negative effect of pipe movement and joint leakage?

• Water damage and potential health hazards

• Corrosion of the pipes
