- Model 21 F679 - Solid Wall PVC Sewer Pipe



Diamond Plastics manufactures 18” through 60” solid-wall Sani-21™ PVC sewer pipe in accordance with ASTM F679, Standard Specification for Poly(Vinyl Chloride) (PVC) Large-Diameter Plastic Gravity Sewer Pipe and Fittings.

This standard contains manufacturing and quality control requirements for large diameter PVC sewer pipe with pipe stiffness’s of either 46psi or 115psi, regardless of pipe diameter (equivalent to sdr 35 or 26 respectively).

This standard was originally published in 1980 and these products have since come to dominate the large diameter sanitary sewer market. Corrosion resistance, superior hydraulics, bottle tight joints, strength and flexibility have resulted in superior performance which is widely recognized.

These products are also suitable for most low-head gravity applications where bottle tight joints and corrosion resistance are desirable. Sani-21™ is Sanitary Sewer Pipe for the 21st Century.
