Certa-Lok™ PVC Well Casing utilizes CertainTeed’s field-proven spline-locking design to form a full strength joint instantly in all weather conditions. No solvents, arc welding, or reinforcement screw attachments are required.

And now, with the introduction of small to medium diameter (4"- 8") Integral Bell Well Casing, the best joint in town just got better! Certa-Lok Integral Bell Well Casing is supplied with a conventional belled-end joint for even faster assembly.

Designed and manufactured to meet or exceed the requirements of ASTM F480, all Certa-Lok PVC Well Casing products are also listed by NSF International as safe for use with potable water. Certa-Lok is ideal for a wide range of water well applications, including:

Domestic Irrigation
Municipal Aquifer
Storage and Recovery
There are many good reasons why most smaller diameter residential systems, and more and more larger public water supply systems, now use PVC as the preferred casing material.
