INITIAL PREPARATION
1. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting.
2. Know the physical and chemical characteristics and limitations of the PVC, PVC cellular core, ABS or CPVC piping
materials that you are about to use.
3. Know the reputation of your pipe and cement manufacturer and their products.
4. Know your own qualifications or those of your contractor. The solvent welding technique of joining PVC, PVC cellular
core, ABS or CPVC pipe is a specialized skill just as any other pipe fitting technique.
5. Closely supervise the installation and inspect the finished job before start-up.
6. Contact the manufacturer, supplier, or competent consulting agency if you have any questions about the application
or installation of PVC, PVC cellular core, ABS or CPVC pipe.
7. Take the time and effort to do a professional job. Shortcuts will only cause you problems and delays in start-up. The
majority of failures in these systems are the result of shortcuts and/or improper joining techniques.
