We stock single wall pipe and fittings from ADS Hancor. This type of pipe is great for all types of drainage projects. Maxi rolls of perforated tubing can be ordered for agricultural field tile. Single wall pipe is also great for the do-it-yourself drainage projects. For example, build a french drain using perforated, single wall pipe or add outlets to your home’s gutter downspouts using downspout adapters and solid single wall pipe to move water from your gutters away from your house.
