60 INSTALLATION
JOINING CPVC PIPE AND FITTINGS WITH ONE-STEP SOLVENT
CEMENT
NOTICE
Read and understand all instructions prior to assembly. Follow all instruc- tions. Failure to follow instructions during joining and testing may result in pipe failure, clogged waterways, or leakage.
Solvent cementing is the only method of joining rigid CPVC pipe and fittings that provides a chemically fused joint. Solvent cementing procedures must be carefully followed. Field experience has shown that problems can occur with improperly solvent cemented joints. Follow the instructions presented below carefully. Do not omit any steps and ensure that all facets of installation are fully understood prior to commencing work. Note the specific instructions and cure times for the TFP-500 or TFP-600 One Step Solvent Cement provided within this handbook. These instructions and cure times must be carefully followed. TFPP offers a demonstration program for installers that is described on Page 5 of this handbook.
NOTICE
Use of solvent cement products other than TFP-500 or TFP-600 One Step Solvent Cement will void TYCO’s warranty on TYCO CPVC Pipe and Fittings.
Avoid applying too much cement. Do not allow the cement to drip be- yond the bottom of fitting socket. Do not allow the cement to puddle in the pipe and fitting assembly. Excessive cement on the pipe and/or fit- ting can weaken the wall of the pipe and/or fitting and may cause cracks when pressure is applied. Failure to comply could result in property dam- age due to leaks. Leaks may not appear until after the pipe and/or fitting is in service.
