New Construction Plumbing FAQ


At what stage of a home build should new construction plumbing begin?

New construction plumbing occurs in two major phases: rough-in plumbing (installed after framing is complete but before drywall, including under-slab ground work, supply pipes, drain vents, and gas lines) and trim-out plumbing (setting toilets, sinks, faucets, water heaters, and garbage disposals after drywall and cabinetry are finished).


Does Gudorf coordinate with custom builders and general contractors in Southern Indiana?

Yes. Gudorf has worked directly with home builders, commercial contractors, and property owners across Southern Indiana since 1964. We provide accurate blueprint take-offs, code-compliant plumbing system design, project scheduling, and free initial project estimates.


What code standards are followed for new construction plumbing installs?

All plumbing rough-ins and finish installs strictly adhere to the Indiana Plumbing Code and local municipal building requirements. Gudorf ensures all water sizing, drain venting pitch, backflow prevention, and pressure testing pass building inspections on the first attempt.
