CPVC piping has been successfully used in homes since 1965. In some cases, CPVC is actually better than copper, since some areas of the country have corrosive water that eats away at copper pipes.
This piping system is designed to be user-friendly and versatile. The outside diameter of CPVC tubing is sized the same as copper pipe. This means grip-style mechanical fittings can be used to join copper to CPVC.
Be aware that many copper- or steel-pipe systems are used as grounding for electrical wiring. Adding CPVC may change your grounding system, so consult an electrician about your plans.
1. Cut CPVC tubing using tubing cutter or handsaw. A cutter makes straight, burr-free
cuts ready for cement or mechanical fitting. Chamfer (taper) the edge with a
utility knife for a better joint.
2. Add shutoff valves with mechanical fittings to CPVC or copper pipe. Add a drop of liquid soap to pipe's end for lubrication. Loosen nut on fitting about two turns and seat pipe into fitting. Hand-tighten each nut.
3. Swab primer onto pipe end and inside fit ting to clean and etch surface. Primer gives cement a better grip. Ventilate the work area and wear a respirator. Some codes permit use of CPVC cement without primer.
4. Apply CPVC cement to outside of tubing and inside of fitting. Push tubing
into fitting with a slight twisting motion and hold for 15 seconds until
joint sets. Initially, the pipe may try to pop out of the fitting. 
5. Support CPVC
lines every 32 to 36 in. (80 to 90 cm) with CPVC supports. Tubing should ply and cap stub-out. After one hour, turn on slide freely within each hanger
to allow movement. Leave 1/2 in. (12 mm) clearance to obstructions to allow
tubing to expand and contract. (continue ...)Recommended Reading
2006 International Plumbing Code - Softcover Version: Softcover Version
The 2006 International Plumbing Code®addresses the design and installation of plumbing systems through requirements that emphasize performance. Provisions are provided for fixtures, piping, fittings, and devices, as well as design and installation methods for water supply, sanitary drainage, and storm drainage. The code provides comprehensive minimum regulations for plumbing facilities using prescriptive- and performance-related provisions. The objectives of the code provide for the acceptance of new and innovative products, materials, and systems.
The 2007-2012 World Outlook for CPVC Schedule 80 Plastics Industrial and Mining Pipe
Book Description
This study covers the world outlook for CPVC Schedule 80 plastics industrial and mining pipe across more than 200 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the % share the country is of the region and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis-à-vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved.

6. Cement stub-out tube to every water supply and cap stub-out. After one hour, turn on water supply to check for leaks.
7. Use water hammer arresters to keep pipes from banging. The ones shown are specifically for CPVC systems. Other types of arresters may be used with appropriate fittings and if the water supply doesn't deteriorate copper.
8. To add shutoff valves for fixtures, turn off the water supply, cut stub-outs
to desired length and add escutcheon plate. Use mechanical grip or cement-on
shutoff valves.
