Troubleshooting
Joint leaks after installation
Ensure proper surface preparation (clean, dry) and correct application of primer and solvent cement. Re-cut and re-weld the joint if necessary, allowing full cure time.
Difficulty inserting pipe into socket
Check for obstructions or damage inside the socket and on the pipe end. Ensure the correct size pipe and fitting are being used. Ensure primer has been applied to soften the ABS slightly.
Fitting discolors over time
While designed for UV resistance, prolonged direct exposure to intense sunlight may cause some fading. Ensure proper ventilation if installed in a confined space.
