The plumbing will be designed with flexible PEX pipe in a home run structure. This means that each fixture runs from the water closet to the fixture with no other branches. While this uses more piping, it provides less issues with trouble shooting. It also means a faster delivery with hot water.
The water from PWSA will run to the water closet and go through a whole house water filter. From the water filter, two lines will split. The first line will run to the cold water manifold, while the second line will run to the electric tankless hot water system before going to the hot water manifold. The pipes will run in the interior walls to prevent water lines from freezing.
