The stages of a new plumbing install

New construction plumbing usually moves through three stages. Underground work comes first: drain and sewer lines are set in trenches before the slab is poured, and sleeves and stub-outs are placed where fixtures will go. Rough-in follows once the framing is up, with supply and drain lines run through walls and floors, and vent pipes taken to the roof. Finish work comes last, when fixtures, faucets, the water heater and appliance connections are set.

Inspections are normally required at each stage, and the work must pass before the next trade continues. Plans and schedules vary by project and jurisdiction, so ask who schedules each inspection.

Questions to settle early

Decide on the water heater type and location before the framing is closed, since venting and gas or electrical needs affect the layout. Think about future needs such as a second kitchen, a pool or a laundry that could be added later. Plan accessible shutoffs and cleanouts. Choose pipe materials with the builder and confirm what the plans specify.

Builders and owner-builders should share the plans, the schedule and the inspection process on the first call, so the contractor can say whether the job fits.

Remodels and additions

Adding a bathroom or a kitchen to an existing house raises different questions. The new fixtures must tie into existing supply and drain lines, vents must be sized properly and the water heater must handle the added demand. If the slab must be cut to run a drain, the work needs planning. Older houses may need updates to meet current code where new work connects.

See water heater installation and replacement for heater sizing and shower and bathtub installation for drain and valve planning.
