Whole-House Repipe in Hawthorne, CA

A whole-house repipe replaces the entire potable water supply system — every supply line from the main shutoff to every fixture. We use PEX-A for most modern repipes (flexible, freeze-tolerant, and faster to install) or Type-L copper when homeowners prefer it. Manifold layouts give every fixture its own home-run line with individual shutoffs, which dramatically improves pressure and isolation.

Repipe candidates in Hawthorne typically share a profile: built between 1940–1965 and 1965–1990, carrying cast iron DWV, galvanized supply, and type-L copper retrofits all reaching end-of-life on the same timeline. The classic symptoms are low pressure, rust-tinted first-draw water, persistent fixture clogs, and recurring slab leaks. We've repiped enough Hawthorne homes from these eras to predict the layout, the failure points, and the right manifold configuration before we walk in the door — which is why our quotes are tight and our timelines are reliable.
