If you have the knowledge of plumbing, this is another part of the work you might be able to do on your own. However, you need to check with your local building codes to ensure the work you do meets local building requirements. Installing plumbing in a new home or new house addition is a good do-it-yourself project. Modifying existing plumbing or connecting new plumbing to existing plumbing can be hard work that may require many special tools to deal with a variety of materials, such as copper, cast iron, galvanized steel and plastic. Remember that different plumbing needs require different sizes and materials in the pipe you use. Sealing joins may require welding, special sealants, and special connectors. In your planning you should have tried to place new plumbing as close as possible to existing plumbing to reduce cost. Connections and seals are critical in preventing leaks. Using the right kind of pipe in the right size is also vital due to the ability of different materials to handle water at certain temperatures.
