Rough Plumbing in Portola Valley – Custom Installations for New Homes & Remodels

Portola Valley homes often involve complex terrain, custom architecture, and high-end features that demand precision plumbing design from the start. From hillside elevations and sloped lots to septic system tie-ins and long-distance main water service runs, every rough plumbing job in this region comes with unique technical requirements.

At Repipe Champions Plumbing and Rooter, we tailor every rough-in system to your blueprint, fixture plan, and elevation challenges. We use professional-grade materials such as PEX for flexibility and freeze resistance, copper for high-pressure supply, and PVC or ABS for robust drainage and venting performance. Our team evaluates pipe routing, backflow prevention, vent placement, and water zoning to ensure every system supports strong, consistent pressure and clean wastewater removal—no matter the property layout.

We also coordinate directly with your builder, architect, or GC to keep installations efficient and code-compliant. Before any wall is closed, we conduct full water pressure testing, flow checks, and ensure the system meets all Portola Valley inspection requirements. Whether your project includes radiant heating, large spas, or energy-efficient water heating, we’ll make sure the plumbing backbone is solid from day one—so your home or ADU performs reliably for years to come.
