Replacing corroded galvanized pipes with modern, leak-proof materials will help improve water quality and valve longevity.

Key Activities:
Systematic water line design
PEX, copper, or PPR pipe upgrades
Manifold installation and balancing.
Regulatory Reference: Material standards per **CPC Chapter 6 (Water Supply)** [1].

Transitioning homes to sustainable heat-pump or tankless water heaters that reduce energy costs and emissions.
Why It Matters:These systems are 3X more efficient than gas. 2026 codes heavily incentivize these to meet California's carbon-reduction goals. As of 2026, California building standards prioritize electric water heating as part of the state’s decarbonization goals.
Key Activities:
Condensate drainage engineering
Dedicated circuit wiring
Unit sizing
Regulatory Reference: Compliance with **California Plumbing Code (Title 24, Part 5)** [2] and Energy Code standards [3].
Main Line & Sewer Laterals
Ensuring your property’s connection to the city sewer main is leak-free and code-compliant.

Key Activities:
HD video inspection
Trenchless "pipe bursting" replacement
Pressure testing for certification.
Regulatory Reference: Compliance with the EBMUD Regional Private Sewer Lateral (PSL) Ordinance [4].
