Direct Cold Water System Quiz

What type of pressure is used in a direct cold water system?

• a. Gravity pressure

• b. Pumped pressure

• c. Mains pressure

• d. Low pressure

Which statement is true about a direct cold water system?

• a. It relies on stored water in a cistern.

• b. It supplies drinking water to every outlet.

• c. It uses a combination of gravity and pumped pressure.

• d. It has variable pressure at all times.

One advantage of a direct cold water system is:

• a. It has a stored supply of water in case of mains failure.

• b. The pressure remains constant at all times.

• c. It is cheaper to install.

• d. It requires more pipework.

A disadvantage of a direct cold water system is:

• a. It requires additional storage tanks.

• b. If the mains is turned off, you are without water.

• c. It provides low water pressure.

• d. It is more expensive to install.

What is a key characteristic of an indirect cold water system?

• a. All taps are fed directly from the mains.

• b. It relies on gravity or pumped pressure.

• c. It uses less pipework.

• d. It cannot provide potable water at every outlet.

Which is an advantage of an indirect cold water system?

• a. It ensures constant pressure even during peak demand times.

• b. It has fewer pipes and is less prone to freezing.

• c. Every draw-off point provides potable water.

• d. It is cheaper to install.

One disadvantage of an indirect cold water system is:

• a. There is no stored supply of water.

• b. The system pressure varies throughout the day.

• c. It requires more pipework in the roof space, increasing the risk of freezing.

• d. Only one draw-off point gives potable water.

In which system can you stop the flow of water from a tap using your thumb?

• a. Direct cold water system

• b. Indirect cold water system (gravity)

• c. Both direct and indirect systems

• d. Neither direct nor indirect systems

How does the pressure vary in an indirect cold water system?

• The pressure is higher near the cistern.

• The pressure is lower near the cistern.

• The pressure remains constant regardless of the location.

• The pressure is unaffected by gravity.

Which type of system is typically used with a combination boiler?

• Direct cold water system

• Indirect cold water system

• Both direct and indirect systems

• Neither direct nor indirect systems
