• UV Protection: White outer wall resists sunlight and heat, ideal for exposed installations.
• Dimensional Accuracy: Consistent outer diameter per ASTM D2729 / CSA 182.1 ensures compatibility with standard fittings and systems.

Connecting Triple Wall Pipe to Other 4 Inch Drainage Products

TripleFlo drain pipe is often installed as part of a broader drainage system that includes other 4 inch pipe products. Depending on project requirements, contractors may connect triple wall HDPE pipe to sewer and drain (S&D) pipe, SDR pipe, or PVC pipe using appropriate transition fittings.

Soleno’s integrated bell design simplifies installation and enhances joint integrity. For non-pressure systems, adhesive sealing (e.g., 3M Scotch-Grip 4693H) is recommended to prevent separation and root intrusion.

TripleFlo Drainage Applications

• Foundation and basement drainage
• Drainage trenches and collectors
• Turf and recreational areas
• Septic leachfields
• Downspout runoff
• Wire ducting

Installations should follow ASTM D2321 for gravity-flow systems and ASTM F481 for leachfields, along with applicable local regulations.
