Build Plumbing Systems That Last From Rough-In Forward
New Construction Plumbing in Eugene for residential projects requiring full system installation and code compliance coordination
Oregon Custom Plumbing installs complete plumbing systems for new residential construction in Eugene, working with builders to meet timelines and ensure every connection is tested before walls close. You coordinate rough-in and top-out phases with framing and inspection schedules, so delays do not cascade through other trades. The work covers water supply lines, drain and waste venting, fixture placements, and all connections required before finishes go in.
Rough-in plumbing happens after framing is complete and before insulation or drywall. This phase includes running supply lines to fixture locations, installing drain and vent pipes according to slope and diameter requirements, and positioning stub-outs where sinks, toilets, showers, and appliances will eventually connect. In Lane County, inspections verify that venting meets current code and that water distribution lines are correctly sized for the home's layout and fixture count.

Why Coordination Between Phases Prevents Costly Fixes Later
You need rough-in work completed before insulation and drywall crews arrive, and top-out finished before final finishes are installed. Oregon Custom Plumbing coordinates with your builder to ensure inspections are scheduled at the right milestones, avoiding delays that push back other trades. The team uses PEX or copper supply lines depending on your budget and preference, and ABS or PVC drain lines based on local code and the home's layout.
After top-out is complete, you will see all fixtures connected, water flowing at correct pressure to every outlet, and drains tested for leaks and proper venting. The system is pressurized and checked before walls are finished, so any issues are resolved while access is still easy. Final connections include hooking up water heaters, installing shut-off valves, and testing each fixture under normal use conditions.
The work does not include site excavation, septic or sewer main installation, or exterior utility connections beyond the foundation entry point. If your project requires specialized systems like radiant floor heating or greywater recycling, those need to be discussed during initial planning so materials and layout accommodate the added complexity.
What Builders and Homeowners Ask About New Construction Plumbing
Builders and homeowners managing new construction projects in Eugene often need clarity on how plumbing installation fits into overall timelines and what factors affect system performance long-term.
What is the difference between rough-in and top-out plumbing phases?
Rough-in includes all supply, drain, and vent lines installed behind walls before insulation, while top-out involves connecting fixtures, testing the system, and completing final connections after finishes are in place.
How do you ensure the plumbing system is sized correctly for the home?
Oregon Custom Plumbing calculates fixture units and flow rates based on the home's layout, number of bathrooms, and planned appliances, ensuring water pressure remains consistent even during peak usage.
When should plumbing inspections be scheduled during the construction timeline?
Rough-in inspections happen after all pipes are installed but before walls close, and final inspections occur once fixtures are connected and the system is tested under pressure.
Why does Lane County require specific venting configurations?
Local code mandates proper venting to prevent sewer gases from entering the home and to ensure drains flow freely without creating airlocks or slow drainage issues.
How long does the plumbing phase typically take in a new residential build in Eugene?
Rough-in usually takes a few days depending on home size, and top-out can be completed in one to two days once the home is ready for fixture installation and final connections.
