What Water Line Installation Covers
Water line installation typically comes up when adding a new fixture or appliance, running a supply line to a new location such as a remodeled kitchen or bathroom, or extending plumbing to an addition. We size and route each new line to meet code and support the fixture it’s feeding.
Appliance and Fixture Lines
Dedicated copper supply for refrigerators, ice makers, dishwashers, and any appliance that needs a clean, correctly sized connection.
New Branch Lines for Remodels
Hot or cold branches run off the existing supply to a new fixture location, a bathroom addition, or a relocated sink.
Laundry Box Installation
A recessed outlet box carrying hot and cold valves and the standpipe connection, set into the wall so the washer hoses stay accessible and the wall stays finished.
Whatever Needs Water, We Run the Line
Interior supply work covers more ground than most homeowners expect. A dedicated line to a new refrigerator. A cold branch to a bathroom addition. Hot and cold runs to a relocated kitchen sink. A laundry box set into a wall that never had one.
Copper is our default here as well. It handles local water chemistry without scaling, meets code, and stays serviceable for decades. PEX goes in where the run calls for flexibility.
We assess the scope, pull permits where the work requires them, run the lines, and leave the site clean. If a new branch is tying into a supply pipe that is already failing, we will say so and point you to the whole house repipe instead of selling you the branch.

Appliance Hookups
Adding a new refrigerator with an ice maker, a dishwasher, a washing machine, or an outdoor hose bib often requires a new water line run to that location. We handle these hookups as standalone jobs or as part of a larger remodel.
New Branch Runs for Remodels
Kitchen and bathroom remodels frequently require new branch lines to move a sink, add a second bathroom fixture, or reroute plumbing to fit a new layout. We coordinate with homeowners and contractors to install these lines before drywall and finishes go in.
Copper Piping as Standard
We use copper piping for water line installation because of its long service life and consistent performance in Bay Area conditions. Every new installation is backed by a 15-year warranty on the piping’s joints, fittings, and connections.

Free Assessment and Flat-Rate Pricing
We provide a free on-site assessment and a flat-rate quote before any installation work begins, so you know the full cost upfront with no hidden fees added later.
Coordinating with Contractors
Water line installation is often just one piece of a larger remodel, and we regularly coordinate directly with general contractors, cabinet installers, and other trades to make sure plumbing lines land in the right spot before finishes go in. We’ll review layout drawings when they’re available, confirm rough-in locations match the final fixture plan, and schedule our visit around the rest of the project timeline rather than working in isolation. This kind of coordination matters most in kitchen and bathroom remodels, where a line installed a few inches off from where a sink or dishwasher ends up can mean costly rework later.

Frequently Asked Questions
Can you run a line to a refrigerator in a finished wall?
Usually yes. We find the nearest suitable supply, cut a small access opening, run the line, and set a shutoff where you can actually reach it. The opening stays as small as the job allows and gets prepped for patching. Where the layout makes a concealed run impractical, we show you the alternative before anything is cut.
Do you install the laundry box, or only the valves?
Both. A recessed laundry box carries the hot and cold valves and the standpipe connection in one unit set into the wall. Installing it as a unit keeps the hoses accessible and the wall finished, which matters more than it sounds like on the day a washer hose finally needs replacing.
What happens to the dishwasher line when the kitchen is being moved?
The old run is capped or removed and a new one is routed to wherever the appliance is going, sized for the fixture and tied into the existing supply. While the framing is open during a remodel is the cheapest moment to do it.
