Piping for drainage and runoff

Flexible Pipe vs Hard PVC

  • I like the flexible perforated pipe for drainage and leach beds rather than the perforated hard PVC pipe. The holes are smaller allowing only water in and evenly spaced in corrugated valleys to carry the water away.
  • I like the hard PVC pipe for non-perforated uses since it is easier to maintain the proper grade for flow through the pipe. However the non-perforated flexible pipe can work work well too.

Low Spots

Use the perforated pipe installed in gravel to collect and carry water away. Drains like this installed up hill from the house can keep significant water from running down hill to the foundation, which in turn would have lead to a wet basement. In heavy clay soils, several lines of perforated pipe may be needed to speed drainage.
