Rough-in plumbing for kitchen and bathroom remodels in Los Angeles, setting water supply, drain, waste, and vent lines before walls and finishes close in.
Overview
Rough-in is the point in a remodel where pipe locations get locked in for good — move a drain line after drywall goes up and you're cutting into finished work. We set water supply, DWV, and gas lines to match the final fixture layout, then pressure-test everything before anything gets covered.
What's Included
01
Water supply, drain, and vent routing planned around the finalized fixture layout and pipe sizing requirements.
02
Hot and cold water lines run to every fixture location, sized and pitched for consistent pressure.
03
DWV piping installed and vented per code so fixtures drain properly once finishes go on.
04
Completed rough-in pressurized and inspected before drywall closes the walls.

FAQ
Once walls are closed, supply and drain lines are hidden — any change means cutting into finished drywall. Locking in pipe locations at rough-in avoids that rework entirely.
Yes. We pressure-test water supply lines and check drain and vent connections before drywall goes up, so any leak shows up while it's still accessible.
It's possible before walls close, but it adds cost and time. We recommend finalizing fixture placement before rough-in starts to avoid mid-project changes.
Cost depends on the number of fixtures, how far new lines have to run from existing supply and drain points, and whether stacks or vents need to be relocated. A straightforward remodel tie-in costs less than a full addition with new rough-in throughout.
We work off the same framing plan as the other trades and schedule our rough-in alongside theirs, so nobody is drilling or notching through work someone else already installed.
