What does plumbing installation include in a new home?

Plumbing installation in a new home includes designing and installing the full water supply, drain‑waste‑vent, and fixture system to code, then pressure and leak testing. Most work happens in two phases: the rough‑in before walls close and the trim‑out when fixtures are set and connected. Proper venting and backflow protection are included so the system drains and breathes correctly. Our team regularly handles these systems throughout the Birmingham area.

Typical inclusions:

• Water service line, main shutoff, and distribution to kitchens, baths, and laundry.
• Sewer or septic connection with correctly sloped DWV piping and accessible cleanouts.
• Water heater installation plus safety devices such as expansion tank and T&P discharge.
• Final setting of sinks, faucets, toilets, tubs, showers, hose bibs, and stop valves.

Your builder and plumber should provide a fixture list and layout and schedule required inspections before drywall.
