Certa-Lok™ Non-Threaded, Corrosion- Resistant PVC Drop Pipe Certa-Lok™ PVC (Polyvinyl Chloride) Drop Pipe offers an instant, ready-to-use joint utilizing CertainTeed’s unique, field-proven coupling/spline locking design, which allows submersible pumps to be set or pulled quickly and with confidence. Certa-Lok PVC Drop Pipe is designed and manufactured to meet or exceed ASTM Specification D1785 requirements (SCH 80). Available in sizes 2" – 8", Certa-Lok PVC Drop Pipe is perfect for a wide range of deep and shallow-well applications, including:
- Domestic wells
- Irrigation wells
- Municipal wells
- Recharge wells
- Test pumps
- Offshore oil platform water supply systems
Certa-Lok™ PVC Drop Pipe utilizes CertainTeed’s field-proven spline-locking design to form a full strength joint instantly in all weather conditions. It does not require the use of solvents, arc welding or reinforcement screw attachments.
Certa-Lok™ pipe provides a restrained joint by utilizing precision-machined grooves on the pipe and in the coupling/integral bell which, when aligned, allow a spline to be inserted, resulting in a fully circumferential restrained joint that locks the pipes together. A flexible elastomeric seal (O-ring) in the coupling and/or integral bell provides a hydraulic seal.
Note: If needed, the joint can be disassembled and re-used to allow for system changes, extension or removal for re-use. Certa-Lok™ joints can be easily disassembled, allowing for system changes, extension, movement or reuse of the entire system.
Certa-Lok™ PVC Drop Pipe is also ideal for a wide range of related water well applications, including:
• Aquifer Storage and Recovery
Standard pipe color for Water Well applications is WHITE.
