What does plumbing installation include in a new home?

Plumbing installation in a new home includes designing the system, running water and drain lines during rough‑in, then setting fixtures and equipment at finish. Most projects follow two phases: rough‑in (pipes, vents, drains) and finish (fixtures, valves, and final connections), with pressure and leak testing before close‑up. We perform these installations across the Eastside, including many Bellevue builds. A good install keeps cleanouts reachable and groups shutoffs where you can actually use them later.

Here’s what’s typically included:

• Water supply lines and shutoff valves to every fixture and appliance.
• Drain‑waste‑vent piping to code, with a main sewer connection or septic tie‑in.
• Water heating (tank or tankless) and optional filtration/softening equipment.
• Set and connect toilets, sinks, tubs/showers, garbage disposal, dishwasher, fridge line, hose bibbs, and sump pump where needed.

Schedule a pre‑construction walk‑through and finalize your fixture list early so rough‑in heights and locations match the finish plan.
