Question 1

What is a downpipe?

Accepted Answer

A downpipe is a vertical gutter pipe that carries rainwater from guttering to ground level, or into a drainage system or soakaway. It helps manage roof water flow, reducing surface run-off.

Question 2

What size downpipe should I use?

Accepted Answer

Most UK homes use 68mm downpipes for standard domestic guttering. For larger roofs, commercial buildings, or areas with heavy rainfall, bigger capacity drainpipes may be needed.

Question 3

What’s the difference between round and square downpipes?

Accepted Answer

Round downpipes have a traditional appearance and suit most domestic or heritage properties. Square downpipes give a sharper, modern profile often used on contemporary buildings. Functionally, square downpipes can offer slightly more capacity, while round downpipes are easier to clean. The best choice depends on roof size, building style, and space available.
