All above ground and below ground horizontal drainage pipes should be laid to an adequate gradient. Gradients from 1 in 40 to 1 in 110 will normally give adequate flow velocities. A gradient of 1 in 80 is suitable for commencing calculations for pipe schemes.

Why does my soil pipe smell?

The soil vent pipe is too small or has a cowl fitted that is too restrictive to air flow, causing a ‘syphon’ effect when water is flushed down the drains and creating a semi vacuum in the pipe. This pulls water out of the trap, causing an imperfect seal and allowing the smell to leak back through the plug hole.
