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
How can the feed to a cistern in an indirect cold water system be isolated?
By closing the gate valve on the cold distribution.
By turning off the mains supply.
By closing the service valve before the float-operated valve.
By using a lever valve on the main supply.
Which system type usually requires more care when fitting showers or mixer taps?
Direct cold water system
Indirect cold water system
Both direct and indirect systems
Neither direct nor indirect systems
