Cold Water Systems in Buildings

What is one of the principles of operation of cold water system component layouts used in multi-storey buildings?

• They use gravity to distribute water.

• They rely on solar power for heating.

• They are designed to minimize water pressure.

• They use wind energy for water distribution.

What is a requirement for large scale storage cisterns?

• They must be made of metal.

• They should be able to store a large volume of water.

• They need to be underground.

• They must be transparent.

What is the function of components used in boosted cold water systems in multi-storey buildings?

• To heat the water.

• To increase water pressure.

• To filter the water.

• To reduce water usage.

What is one method of treating water for use in buildings?

• Boiling the water.

• Using chemical disinfectants.

• Filtering through sand.

• Exposing to sunlight.

What is the method of operation of different types of boosted cold water supply systems for buildings?

• They use solar panels.

• They rely on electric pumps.

• They use wind turbines.

• They depend on manual pumping.

In what situations might rainwater harvesting be appropriate?

• In areas with frequent rainfall.

• In desert regions.

• In places with abundant groundwater.

• In urban areas with no rainfall.

What is the purpose of stop valves in a multi-storey system layout?

• To regulate the flow of water to individual properties

• To increase the water pressure in the building

• To provide heating to the building

• To control the electrical supply to the building

In the recommended locations of stop valves for a block of flats fed from a common supply pipe, where is the main internal stop valve located?

• At the top floor

• At the ground floor

• In the middle of the building

• Outside the building

Where must the internal stop valve be located in a premises?

• Below floor level

• Above floor level

• In the middle of the room

• Outside the premises

What is the purpose of fitting a valve to every supply pipe supplying water to premises?

• To increase water pressure

• To enable the supply to be shut off to those premises without shutting off the supply to any other premises

• To reduce water consumption

• To filter the water
