Plumbing Installation for New Construction 

The plumbing system is an integral part of any home or commercial property, so installation is essential for any new construction project. The new construction plumbing is completed in stages at various points in the construction process. 

The three stages of new construction plumbing are: 

  • Underground rough in phase – This phase of the plumbing installation happens when the walls of the basement have been poured. The plumbers will locate the connections for water supply and waste and determine where the water and sewer lines will connect to the building. 
  • Above ground rough in phase – During this phase, the water lines, drains, and vent pipes will be installed. This involves installation of showers, shower bases, and bathtubs. If the property will use gas, the gas lines are installed during this phase of the new construction plumbing process. 
  • Finishing phase – All plumbing fixtures are installed, including sinks, showers, toilets, water heaters, and any other water using appliances. 

ADUs are becoming extremely popular in California construction. ADUs, also known as granny flats or backyard cottages, are now being used for more than only housing the in-laws. These small dwellings are a great way to provide much needed additional housing and a supplementary source of income for the homeowner. 

The steps required for plumbing installation for an ADU is the same as for any other residential construction project, just on a smaller scale. ADUs need a kitchen and a bathroom, so the building will require indoor plumbing fixtures, water lines, drains, and underground water and sewer lines to connect the dwelling to the utilities. There are specific code requirements for ADU construction. 

Whether you are building a large home or an ADU, you will need an experienced plumbing contractor to handle the installation of the various components of the plumbing system. Installing ADU and new construction plumbing in Monterey, CA requires a contractor with the resources, expertise, and knowledge of building codes to ensure that the job is done right and passes all inspections.
