What is the primary ventilated stack most commonly used for in domestic dwellings?

• To provide extra ventilation for appliances

• To serve as the main drainage system

• To eliminate the need for a separate ventilating stack

• To increase water pressure in the system

Why does the primary ventilated stack not require an extra ventilating stack?

• Because it is used in commercial buildings

• Because appliances are closely grouped around the stack

• Because it is only used for small systems

• Because it is a temporary installation

In what situation is the primary ventilated stack used?

• When the discharge stack is too small

• When pressure fluctuations need to be increased

• When the discharge stack is large enough to limit pressure fluctuations

• When additional ventilation is required

What is the recommended gradient for bends and branches in a primary ventilated stack system?

• 5º

• 2.5º (1:40)

• 10º

• 1º
