What is Rough in Plumbing?

New construction plumbing generally suits 2 categories, rough in plumbing and finish plumbing. Rough-in plumbing is the process of installing vents, sewage systems, connections and water supply lines. Throughout the finish plumbing phase, plumbers will finish installations and connections to get the house or building ready for use.


It is essential to make sure that all rough framing in your brand-new building house is finished prior to sending in your plumber to start the rough in plumbing phase. You’ll likewise want to make sure your plumbing professional has all item specifications, strategies, cabinet designs, and so on prior to beginning. It is also useful for your contracted plumber to walk the framed house (possibly even with the home builder present) to strengthen and verify locations of each plumbing component, tubs, water heater, washer/dryer connections, the main water hookup, and the supply lines required to link the water and drain lines.

The Rough In Plumbing Stage:

  • Excavation and laying of underground pipes that run from utility connections to a main structure is finished.
  • Pipes are routed through wall cavities
  • Vent stacks are run to the roofing system
  • Drain lines and water system lines are linked to sewer systems, septic tanks, or main water supply valves.
  • Pipeline connections are made
  • No fixtures or end aspects will be installed at this phase (absence of coverings helps the inspector).

Crucial Factors To Consider Throughout This Stage:

  • Gravity is important for draining, so wastewater drain line pipes should be set up in a position that angels downwards. If not angled appropriately, water and waste will not drain efficiently. It is necessary to comprehend that angles too steep can likewise cause concerns associated with draining pipes too quickly.
  • The wastewater system should likewise be vented to guarantee waste is gotten rid of efficiently and securely.
  • After the rough in plumbing phase, once inspection passes, the remaining parts of the plumbing system (or finish pipes) can be finished later on in the building procedure.
