CPVC Properties

• Unlike metal pipes, CPVC, a plastic-like material, may be cut easily and does not corrode in the presence of acidic water. Because it is easy to work with, CPVC is commonly used for water pipes. CPVC piping is much more affordable than copper piping, at the time of publication, and it may be used in many areas of the home.
  
  

Water Pipes

• Water pipes are a huge consideration when it comes to building or remodeling any home. Depending upon the area where you live, CPVC piping may be inappropriate for an attic. Generally, attics are poorly insulated and tend to get much colder than the rest of the home. For this reason, CPVC pipes are rarely used on outside walls and in attics where cold and freezing temperatures are the norm. When water freezes in your pipes, even plastic pipes, it swells and increases in size. The expanded water, ice, may burst through and rupture the pipes to create serious leaks and other problems.
  
  

Licensing

• Home and property owners may be required to take out licenses or permits when building or remodeling their property. You must decide how you plan to run your pipes and submit these plans to your local city or county government before making these changes to your property. You can hire a licensed, professional plumber to take care of this business end when you are making changes in your home or property. It is part of the plumber's job to obtain all permits prior to working on the project.
  
  

Plumbing Code

• All states, counties, parishes and cities have their own plumbing codes that must be followed. Water pipes must be measured by a certain diameter, strapped into place against walls and fit together properly. If CPVC is not acceptable material for your attic pipes, a professional, licensed plumber plumber can recommend other options.
