For what type of installations are low carbon steel pipes and fittings rarely used?

• Commercial systems

• Industrial systems

• Domestic installations

• Outdoor installations

Identify the tool shown in the image used for LCS pipework installations.

• Manual press tool

• Electrical press tool

• Hydraulic press tool

• Pneumatic press tool

Why are polybutylene pipes and fittings becoming the material of choice for new-build installations?

• Because they are the cheapest option available

• Due to their durability and strength

• Because of their flexibility and ease of installation

• They are the only materials that can be used for plumbing

What must be used to make connections to any heat-producing appliance?

• Polybutylene for the entire connection

• Copper for the metre nearest the appliance

• Plastic connectors throughout

• Steel pipes for better heat resistance

What combination is acceptable at the heat emitter?

• Copper only

• Polybutylene only

• A combination of polybutylene and copper

• Steel and polybutylene

At what temperatures do the flow and return pipework expand and contract?

• Flow at 50°C and return at 70°C

• Flow at 70°C and return at 50°C

• Both at 60°C

• Both at 70°C

What should be done at the installation stage of pipework to account for expansion and contraction?

• Tighten all the joints securely

• Make provision for expansion and contraction

• Install the pipes without any notches

• Use polybutylene pipe only

When installing pipes in wooden floors, what is important to consider?

• The color of the pipes

• The material of the pipes

• Enough room for notches

• Enough room should be allowed in any notches made

Why is it critical to maintain proper clipping distances for pipes, especially for polybutylene pipes?

• To reduce the cost of installation

• To make the installation process faster

• To prevent damage to the pipes during installation

• To prevent damage to building fabric by expansion of longer runs

What can be used to accommodate pipework expansion on larger systems, if necessary?

• Sealants

• Adhesives

• Expansion joints

• Smaller pipes
