Multi Family & Commercial Repiping

SoCal Repipes provides professional multi family and commercial repiping services for apartment buildings, condominiums, townhomes, and occupied commercial properties throughout Southern California. We specialize in replacing aging water piping systems while coordinating work around tenants, building operations, and code requirements.

What Is Multi Family and Commercial Repiping

Multi family and commercial repiping involves replacing shared hot and cold water lines that serve multiple units or commercial spaces. These systems often include vertical risers, horizontal mains, pressure regulation components, and unit branch lines that require specialized planning and execution.

Unlike single home repipes, multi unit projects require phased water shutdowns, tenant coordination, and strict adherence to commercial plumbing codes. This work should only be handled by contractors experienced in large scale repiping.

Properties We Service

• Apartment buildings
• Condominium complexes
• Townhomes with shared plumbing systems
• Duplexes and triplexes

Signs a Building Needs Repiping

• Recurring leaks in multiple units
• Low or inconsistent water pressure
• Rust colored or discolored water
• Frequent slab or wall pipe repairs
• Galvanized or aging copper piping
• Insurance or inspection requirements

PEX vs Copper for Multi Unit Repiping

Material selection depends on building layout, water chemistry, pressure demands, and long term ownership goals.

PEX piping is often used for its flexibility and speed of installation, which can reduce access openings and labor time in occupied buildings.

Type L copper piping is commonly selected for its durability, temperature resistance, and long service life in commercial applications, especially where water quality or fire system integration is a concern.

Our team evaluates each building individually and provides material recommendations based on performance, longevity, and code compliance.

How Repiping Is Performed in Occupied Buildings

Commercial and multi family repiping is completed in phases to minimize disruption. Our process includes advance notice to tenants, scheduled water shutdowns, and coordinated access to units.

• Site walkthrough and system evaluation
• Phased work plans by stack or wing
• Temporary water management when required
• Clear tenant communication schedules
• Pressure testing and inspections

Code Compliance and System Protection

All multi family repiping work is performed in accordance with California plumbing codes and local jurisdiction requirements. This includes proper pipe sizing, pressure regulation, seismic strapping, and backflow protection where applicable.

We also assess pressure reducing valves and system balance to protect fixtures and appliances after the repipe is completed.
