Frequently Asked Questions (FAQs)

1. Does a channel drain need to slope?

Slopes are unnecessary A common misconception is the belief that a slope is needed for water to drain effectively. However, this is not necessary. As long as the channel is laid flat and level, the water will be able to flow, providing the outlet is below the level of the channel.

2. How much should a channel drain slope?

A built-in slope of 0.7% allows optimal flow rates to be maintained system wide; neutral sections are also available.
