Cold Water - Mock 2

The legal requirements for the installation of cold water services are stated in the

• British Standards

• Building Regulations

• Water Regulations

• Construction Regulations

To establish whether a cold water supply to a dwelling is adequate to feed all the plumbing appliances, the best item of equipment to use is a

• water meter

• manometer

• flow meter

• air test gauge

A plumbing operative identifies that a low pressure cold water system does not provide a suitable flow rate to an electric shower, supplied by the plumbing company, that is to be installed. Who should be the first point of contact?

• Water company

• Local authority

• Customer

• Supervisor

Which one of the following is approved for use on underground service pipes?

• Solder fittings with lead / tin solder

• Push fit plastic fittings

• Type ‘B’ compression fittings

• Type ‘A’ compression fittings

The Water Regulations state that the minimum permissible distance from the external wall of a dwelling, to where an uninsulated service pipe enters the inside of the building, is

• 150 mm

• 250 mm

• 550 mm

• 750 mm

The last isolation valve on a supply pipe to a cold water storage cistern is the

• float operated valve

• draining valve

• servicing valve

• supply stop valve

The recommended clip spacing for a vertical cold water service pipe in 15 mm copper is

• 1.0 m

• 1.3 m

• 1.5 m

• 1.8 m

Refer to Figure 1. The system component indicated by the British Standard symbol shown is a

• supply stop valve

• float valve

• check valve

• draining valve

In addition to a warning pipe, an overflow pipe is required on cisterns of more than what capacity?

• 115 litres

• 230 litres

• 1000 litres

• 1250 litres

The main advantage of a direct system of cold water, compared to an indirect system of cold water, is that

• there is much less chance of noise in the system

• it has cheaper materials and installation costs

• the pressure of the hot water is improved

• the pressure to the float valves is reduced
