The next phase for the interior of the house is the rough-in of the initial plumbing.  The bathtubs and showers are set in place and the water and sewer pipes are run throughout the house in preparation for the toilets, faucets, tubs and sinks the will make up your indoor plumbing.  Our home features a newer type of plumbing called PEX.  PEX is a polymer tubing used for water lines that is easy to install since it is flexible, and connects to fixtures using pressure fittings and ring clamps. PEX has several advantages over copper or PVC in addition to the flexibility.  There are fewer joints when using PEX as the pipe is virtually continuous from the source to the fixture, this ensures less leaks from faulty or worn joints.  Another advantage of PEX is the resistance to freezing, as PEX will slightly expand, preventing pipe bursts like PVC or copper.  Ryland’s contractor ran red colored lines for hot feeds and blue for cold to make plumbing that much easier now and later when expanding the system.   The sewage plumbing has several traps for cleanout in place as well for easy maintenance.
