Certa-Lok PVC Drop Pipe is fast and easy to set and pull. You can assemble or disassemble the Certa-Lok joint in seconds – by hand, without any special tools. Since there are no threads, time spent rotating threaded pipe is completely eliminated. Follow these simple steps for rapid joint assembly:

1. Clean:Clean the joining surfaces and make sure gaskets are clean and evenly seated in the gasket grooves.

2. Lubricate: If lubrication is needed to ease joint assembly, soapy water or CertainTeed-approved PVC pipe lubricant can be applied to the joining surfaces prior to assembly. Apply only to the exposed gasket surface and to the tapered end of the drop pipe.

CAUTION: To maintain joint integrity, do not apply lubricant to the spline or to the spline grooves.

3. Assemble: Insert the drop pipe into the coupling until it seats against the coupling stop. This automatically aligns the locking grooves for receiving the spline. The spline is then inserted through the entry hole until it is fully seated. This securely locks the joint, while the gasket is designed to provide a reliable, watertight seal. The spline may then be cut so that only a short length protrudes from the coupling to facilitate future disassembly.In circumstances where there is a need to prevent sand infiltration into the joint (which can make coupling disassembly more difficult), wrap the coupling edges with waterproof tape and seal the spline entry holes with putty or similar material.

4. Tighten torque control screws: Using an allen wrench, tighten the torque control screws into the coupling until each just touches the pipe. Then tighten each screw one-half to one full turn or until snug.

CAUTION: Do not over-tighten. Over-tightening may result in leakage and/or coupling failure.
