AC 2.1 Part 3 Water Supply in Multi-Storey Buildings

What does the phrase 'multi-storey' refer to in the context of water supply?

• Buildings with multiple floors

• Buildings too tall for direct water supply

• Buildings with multiple water tanks

• Buildings with underground water systems

What is required to lift water in multi-storey buildings?

• A water heater

• A filtration system

• A boosting pump

• A drainage system

According to the Water Supply (water fittings) Regulations, what is forbidden without prior consent of the water undertaker?

• Pumping direct from a mains supply when the flow rate is greater than 12 litres per minute

• Pumping direct from a mains supply when the flow rate is less than 12 litres per minute

• Pumping direct from a mains supply when the flow rate is exactly 12 litres per minute

• Pumping direct from a mains supply at any flow rate

What is a characteristic of a direct boosted cold water system?

• Uses a pressure vessel

• Connects to a drinking water header or cistern

• Relies on gravity

• Utilizes solar panels

Why should excessive pressure be avoided in the water supply system?

• It can cause leaks

• It can lead to stress on valves and water wastage

• It can increase water temperature

• It can reduce water flow

How are the pumps shut down in the system?

• By a temperature sensor

• By a pressure switch or time control

• Manually

• By a water level sensor

In what situation is the complex cold water system usually used?

• When there is only one storage cistern

• When multiple storage cisterns are fed at various levels

• When the water system is small

• When float switches are sufficient

What is the function of the air inlet valve in the system?

• To release water

• To allow air into the system

• To stop water flow

• To filter air

What is the function of the pneumatic pressure vessel in the system?

• To filter incoming water

• To store compressed air

• To regulate water pressure

• To drain excess water

Where does the unboosted mains cold water supply go in the system?

• To the upper floors

• To the lower floors

• To the pressure switches

• To the duplicate pumps
