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 Winslow 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.

Codes & Permits for New Construction Plumbing in Winslow
In Winslow, plumbing permits come from the Local Plumbing Inspector at the Winslow Code Enforcement Office (114 Benton Avenue, Winslow, ME 04901, (207) 872-2776 ext. 5207 (fax (207) 872-1999)). With 7,948 residents, Winslow is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The town's historic Fort Halifax blockhouse, on the riverfront peninsula at the two rivers' confluence, was swept away by the Kennebec River during the April 1, 1987 flood and later rebuilt — illustrating documented flood risk along the town's river frontage.

How J&R Handles New Construction Plumbing in Winslow
- With 7,948 residents, Winslow must enforce the Maine Uniform Building and Energy Code, so new work is planned to the 2021 IRC and energy code as well as the plumbing code, including R-3 insulation on 3/4-inch and larger hot-water piping.
- We file the permit application with the Winslow Code Enforcement Office before rough-in, schedule the rough-in inspection before walls close, and the final before occupancy.
