Multiple Choice

Why is it important for buildings to have a rainwater guttering system?

• To prevent water damage to the building structure

• To improve the appearance of the building

Multiple Choice

Which part of the rainwater guttering system is responsible for carrying water down from the roof to the ground?

• Gutter

Multiple Choice

Rainfall in the UK tends to be heaviest along which coast?

Multiple Select

Which of the following are requirements set by British Standards for gutter installation?

• Offset bend

• Shoe

• Fascia clip

• Downpipe clip

Multiple Choice

Which of the following statements about downpipe clips is correct?

• They secure the downpipe to the wall and should be spaced about 1.8m apart vertically.

• They are used to create a 'swan neck' in the downpipe.

• They direct rainwater into a gulley.

• They support the gutter run to give the correct gradient.

Multiple Choice

Why is it important to insert gutter fittings only up to the thermal expansion marks?

• To allow for expansion and prevent buckling or dislocation

• To make installation easier

• To improve water flow

• To reduce the number of clips needed

Multiple Choice
