Plumbing rough-ins

A plumbing rough-in is the stage of a project where all the drain, vent and water supply piping is installed inside the walls and floors, before drywall goes up and fixtures are set. Panacci Plumbing does rough-ins for basements, additions, renovations and new construction in Hamilton, Burlington, Oakville, Milton and the Niagara Region, for both homes and businesses.

What a rough-in includes

  • Drain, waste & vent (DWV) piping that carries wastewater out and lets the system breathe
  • Hot & cold water supply lines run to each fixture location
  • Fixture stub-outs for toilets, sinks, tubs, showers and appliances
  • Shower valves, laundry boxes & floor drains set in place before the walls close
  • Testing to confirm the new lines are sound before inspection

How a rough-in project runs

  1. Layout & free estimate. We confirm fixture locations, drain routes and where the new lines tie in.
  2. Permit. New plumbing usually needs a permit from your municipality.
  3. Rough-in. We install the drain, vent and supply piping once framing is done.
  4. Test & inspection. The lines are tested, then inspected before insulation and drywall.
  5. Finish. After the finishes are done, we come back to set the fixtures.

Basement below the sewer line? Fixtures that sit lower than your main drain may need a sewage ejector pump. We'll plan for it at the rough-in stage so there are no surprises. Also consider adding a backwater valve while the floor is open.

FAQ

Plumbing Rough-Ins: common questions

What is a plumbing rough-in?

It's the first stage of plumbing on a build or renovation. The drain, waste and vent pipes and the hot and cold water lines are run to where each fixture will go, then capped until the finished fixtures are installed.

When does the rough-in happen in a project?

After framing and before insulation and drywall. The walls need to be open so the pipes can run through them, and the work usually has to be inspected before they're closed.

Does a plumbing rough-in need to be inspected?

In Ontario, new or relocated plumbing generally needs a permit and an inspection of the rough-in before the walls and floors are covered. Check with your municipality's building department for your project.

My basement already has a rough-in. Can I use it?

Often, yes. Existing rough-in stubs can save a lot of work, but their location and condition matter. We'll check where they are and whether they'll suit your layout during a free estimate.

Do you do commercial rough-ins?

Yes. We install plumbing systems for commercial spaces, including water and sewage systems tailored to the building, all up to code.
