How Your Drain-Waste-Vent System Works
- Fixture drains — sinks, tubs, and toilets
- Main stack — collects branch lines and vents through the roof
- Vent — keeps trap seals from siphoning dry
- Cleanout — access point for clearing clogs
- Building sewer — carries wastewater to the street main
New Construction Plumbing for Portland Homes
We plumb new homes, additions, garages with living space, and gut renovations. That covers water supply lines in PEX or copper, drain, waste and vent piping, gas piping for appliances and heating equipment, and the water heater, with every run laid out before the walls close so fixtures land where your plans say they should.
What Are the Stages of New Construction Plumbing?
New construction plumbing happens in three stages. Underground and rough-in come first: drain and sewer connections under the slab or through the foundation, then supply, drain, waste and vent piping run through the open framing. Rough-in is pressure-tested and inspected before insulation and drywall go up. Top-out and trim follow once the walls and floors are finished: setting toilets, sinks, tubs, showers and faucets, connecting the water heater and appliances, and testing every fixture. We schedule each stage around your builder’s timeline so the plumbing never holds up the next trade.
