Single-wall or dual-wall?

Dual-wall has a smooth interior for better flow and is more crush-resistant. Worth the extra cost for buried applications.

Solid for transporting water from point A to B. Perforated for French drains where you want to collect groundwater.

Code Requirements

Must maintain minimum 1% slope. Must discharge to approved location. Cannot connect to sanitary sewer. Dual-wall or rigid pipe may be required in some jurisdictions.

Buying Tips

Use dual-wall pipe for any buried application - the smooth interior flows much better than single-wall; Maintain at least 1% slope (1/8 inch per foot) throughout the entire run; Terminate with a pop-up emitter to prevent animals from entering the pipe
