Detailed New Construction Plumbing—Step by Step

Our local Charleston plumberswork in sync with your construction timeline—collaborating with architects and contractors to plan every detail of the plumbing system so it fits your layout and stands up to daily use.

What our process includes:

Design and Layout Planning

Before laying pipes, we study your blueprints and engineer a complete plumbing layout prioritizing access, efficiency, and future maintenance. This includes sizing your water supply and sewer line placement, setting vent locations, and avoiding conflicts with electrical or HVAC systems. 

We create a plumbing system that performs consistently under daily pressure and makes repairs easier.    
 

Piping, Sewer Lines, and Gas Installation

Our licensed crew installs all water, drain, and gas line solutionsduring the rough-in phase. We securely anchor every pipe, use materials matching your soil and building type, and route each line to minimize friction loss or pressure issues. Every component meets the latest IPC and IFC standards, and we document each step to speed up inspection approvals.    
 

Need specific gas line repairs or modifications to meet Charleston’s Code of Ordinances? We’re familiar with every detail of Charleston’s plumbing requirements and make fast, accurate changes to stay on schedule.    
 

Municipal Hookups and Testing

We handle all final tie-ins to the public utility grid, including water mains, sewer access, and gas meters. That includes installing backflow prevention devices, testing the shutoff valves at the property boundary, and managing inspector visitsso your timeline stays on track.    
 

Fixture Trim-out and Appliance Setup

After the flooring, paint, and tile are finished, we return for the fixture installationphase. This includes faucets, toilets, shower valves, hose bibs, and other essential hardware. We install each one to spec, checking for flow, seal integrity, and placement accuracy.    
 

Then we hook up appliances like water heaters, washing machines, dishwashers, and garbage disposals. Each connection is tested with cold and hot water, and we confirm all venting and drain paths are clear before final signoff.    
 

Final System Testing

We run full pressure tests on water supply, drain, and gas lines to confirm leak-free performance and strong water pressure throughout the building. We verify flow rates at every fixture and ensure your system passes city inspections.    
 

Residential and Commercial Projects 

Our team has built plumbing systems for everything from single-family homes to commercial properties like office buildings, restaurants, and mixed-use developments. We offer tailored commercial plumbing optionsdesigned for long-term usage and high-demand performance.    
 

That includes everything from multi-basin sinks and tankless water heaters to grease interceptors, mop sinks, and code-compliant restrooms. When you need a commercial plumbing service crew to keep pace with your build schedule and business plan, ALL Plumbing is ready.
