Your lateral goes further than you think
In Costa Mesa, the sanitary district treats the sewer lateral as private property all the way to the point where it meets their main — normally under the middle of the street. A break in the parkway, under the kerb or beneath the asphalt is still the property owner’s to repair.
That is worth knowing before a problem arrives, because it changes what a camera inspection is worth. The district even runs a rebate programme for a CCTV inspection of the lateral or the installation of a ground-level cleanout.
What the camera decides
Film first, dig second — the footage decides everything that follows.
- Roots at a joint: often a targeted repair of that joint rather than the whole line.
- A belly or low spot holding water: cleaning will never fix it; the section has to be re-laid to fall.
- An offset joint from ground movement: repair or replacement of that section.
- A collapsed or crushed section: excavation, and no lining method will help.
- Sound pipe with build-up: a cleaning job, not a repair job, and we will say so.
Repiping: when the supply side has had enough
A repipe is right when the evidence stacks up: pressure well below normal, rusty water on the first draw, and a history of pinhole repairs. Any one of those alone is not a repipe; together they are the pipe telling you it is finished.
The work is planned around access — attics, closets, cabinet backs — so the number of openings stays small, and everything opened is patched. On a single-storey Orange County house it is a small number of days with the water back on each evening, not a fortnight of camping in your own home.
Galvanised, copper, PEX: what is in your walls
Houses built before about 1960 often have galvanised steel supply, which corrodes from the inside and closes the bore gradually. That is why the pressure loss is so gradual nobody notices until a visitor mentions the shower.
The 1960s through the 1990s is mostly copper, which lasts well until it starts pinholing. Newer houses and most repipes today use PEX, which does not corrode, tolerates movement and can be run to a manifold so every fixture has its own shutoff.
