Follow water from the incoming service to the finished fixture. Ten illustrated stages show the routing, protection, insulation, and checks behind a luxury home’s supply system.

Water demand, fixture locations, and the route from the incoming service are coordinated before piping begins. The layout reserves space for separate hot and cold supplies, insulation, and accessible valves.
A continuous copper service line follows its planned route toward the home. This view shows prepared bedding and a protected building entry before backfill; the drinking-water service remains separate from wastewater piping.
An accessible main shutoff allows the building supply to be isolated. Where required by incoming static pressure, a pressure-reducing valve controls pressure delivered to the distribution system, with room left for adjustment and service.
The main copper runs carry water through the home and feed smaller fixture branches. This unfinished rough-in view shows the routing and compatible supports while joints remain exposed; hot-water insulation follows before concealment.
Dedicated hot and cold branches rise toward the fixture locations without crossing into one another. Compatible clamps hold the runs in place, and sleeves protect the floor penetrations. This is the stage before required hot-water insulation is installed.
Hot and cold outlets are aligned with the planned vanity and faucet positions. Blocking and secure fittings hold the connections steady for the finish work, while temporary caps protect the open supply system.
Insulation limits heat loss along the hot-water distribution route. This installation-in-progress view shows insulated runs and fittings, with short terminal sections still exposed. Required coverage at the remaining connections is completed before the work is closed in.
When a pressure regulator or backflow device creates a closed system, heated water needs an approved way to accommodate expansion. A properly selected potable-water expansion tank connects on the building side of the restriction and is securely supported.
The water-filled piping is pressure-tested while joints are still visible. Capped outlets and a connected gauge allow the system to be checked for leakage, with any issues corrected before required inspection and concealment.
After finishes are complete, accessible fixture shutoffs and compatible supply connectors are installed. The lines are flushed, joints are checked with water flowing, and hot and cold operation is confirmed before handover.
