Explain the working principles of specialist system components in hot water plumbing systems.

• They regulate water temperature and pressure.

• They are used to filter impurities from water.

• They are designed to prevent water leakage.

• They enhance the aesthetic appeal of plumbing fixtures.

Which of the following is an advantage of infra-red operated outlets?

• They are difficult to operate.

• They spread germs and bacteria.

• They help with water conservation.

• They cause scalding injury.

Non-concussive taps are usually used in which of the following places?

• Residential homes

• Public restrooms

• Industrial factories

• Private offices

Non-concussive taps operate by:

• Releasing water for a set period of time

• Maintaining a constant flow of water

• Requiring manual operation to stop

• Using sensors to detect hand movement

The hot and cold water connections to the bath/shower mixer should be fitted with double check valves because:

• They prevent backflow of water.

• They increase water pressure.

• They reduce water temperature.

• They enhance water flow.

The purpose of a retaining ring on the shower hose is to:

• Prevent the hose from detaching

• Increase water pressure

• Decorate the shower

• Reduce water temperature

What is the function of the bath/shower mixer valve in the plumbing system?

The primary purpose of flow limiting valves is:

• To regulate the flow rate in a system

• To increase the pressure in a pipeline

• To filter impurities from fluids

• To measure the temperature of a fluid

How can the flow rate be changed in flow limiting valves?

• By adjusting the valve opening

• By changing the fluid type

• By altering the pipe diameter

• By modifying the temperature

Select the correct benefits of using flow limiting valves.

• Improved system efficiency

• Reduced energy consumption

• Enhanced safety

• Increased system pressure
