Explain the difference between a drainage system and a soakaway in the context of rainwater systems.
A drainage system directs rainwater to sewers, while a soakaway allows water to soak into the ground
Both systems store rainwater for later use
A soakaway is used only in commercial buildings, while drainage systems are for residential use
A drainage system is always combined, while a soakaway is always separate

What is the main principle behind gravity rainwater systems in buildings?
Using pumps to move water away
Allowing rainwater to run off the roof into gutters and downpipes using gravity
Storing rainwater on the roof
Letting rainwater penetrate the property
Explain how gravity assists in the functioning of rainwater systems in buildings.
Gravity helps water evaporate from the roof
Gravity channels rainwater from the roof into gutters and downpipes, moving it safely away from the property
Gravity causes water to stay on the roof
Gravity increases water penetration into the property
A property owner notices water pooling near the foundation after rain. Using your understanding of gravity rainwater systems, what could be a possible cause and solution?
The gutters are channeling water away properly; no action needed
The downpipe may be blocked, preventing water from being safely directed away; clearing the blockage could solve the issue
The roof is absorbing all the rainwater; replace the roof
The rainwater system is designed to create pooling; install more pools

Facia
Box end
What is the main function of the downpipe in a rainwater system?
