Test dry fit of the joint Tapered fitting sockets are designed so that an interfaced fit should occur when the pipe is inserted about 1/3 to 2/3 of the way into the socket. Occasionally, when pipe fitting dimensions are at the tolerance extremes, it will be possible to fully insert dry pipe to the bottom of the fitting socket. When this happens, a sufficient quantity of cement must be applied to the joint to fill the gap between the pipe and fitting. The gap must be filled to obtain a strong, leak-free joint. D. Inspection, cleaning, priming Visually inspect the inside of the pipe and fitting sockets and remove all dirt, grease or moisture with a clean dry rag. If wiping fails to clean the surfaces, a chemical cleaner must be used. Check for possible damage such as splits or cracks and replace if necessary. Depth-of-entry Marking the depth of entry is a way to check if the pipe has reached the bottom of the fitting socket in Step F. Measure the fitting depth and mark this distance on the pipe O. D. You may want to add several inches to the distance and make a second mark as the primer and cement will most likely destroy your first one. Apply primer to the surface of the pipe and fitting socket with a natural bristle brush. This process softens and prepares the PVC or CPVC for the solvent cementing step. Move quickly and without hesitation to the cementing procedure while the surfaces are still wet with primer. E. Application of solvent cement • Apply the solvent cement evenly and quickly around the outside of the pipe at a width a little greater than the depth of the fitting socket. • Apply a light coat of cement evenly around the inside of the fitting socket. Avoid puddling. • Apply a second coat of cement to the pipe end. STEP E F, Joint assembly Working quickly, insert the pipe into the fitting socket bottom and give the pipe or fitting a 1/4 turn to evenly distribute the cement. Do not continue to rotate the pipe after it has hit the bottom of the fitting socket. A good joint will have sufficient cement to make a bead all the way around the outside of the fitting hub. The fitting will have a tendency to slide back while the cement is still wet so hold the joint together for about 15 seconds. STEP F G, Cleanup and joint movement Remove all excess cement from around the pipe and fitting with a dry cotton rag. This must be done while the cement is still soft. The joint should not be disturbed immediately after the cementing procedure, and sufficient time should be allowed for proper curing of the joint. Exact drying time is difficult to predict because it depends on variables such as temperature, humidity and cement integrity. For more specific information, you should contact your solvent cement manufacturer. • Cans of cement and primer should be closed at all times when not in use to prevent evaporation of chemicals and hardening of cement. • They are also very flammable and should be kept away from heat or flame.
