“Newer” Homes Are Quietly Getting Old
The signature problem here is the copper pinhole leak. The thin-wall copper used through the building booms of the 80s and 90s corrodes from the inside — aggressive water chemistry and decades of flow wear microscopic pits into the pipe until one finally weeps through. The first leak often shows up as a stain on a ceiling or a musty smell in a wall, and where there’s one pinhole, siblings usually follow. We repair individual leaks, and when a home starts producing them in series, we lay out honest repipe options rather than selling you an endless sequence of drywall patches. The same age curve applies to original water heaters, pressure regulators, and angle stops — components with 15-to-25-year lifespans, in homes now older than that.

Why Neighbors Here Call Sedco
Rancho San Diego sits in Otay Water District territory, and its imported supply carries the mineral load typical of the region — one reason we install so many filtration and softener systems in these communities, and one factor in that copper corrosion. Beyond water chemistry, what keeps neighbors calling back is simpler: a locally owned company, a C-36 license, flat-rate quotes approved before work starts, and technicians who respect HOA parking rules and leave the house cleaner than they found it.
Frequently Asked Questions
How close is Sedco Plumbing to Rancho San Diego?
Very — our El Cajon base is roughly 10–15 minutes away via Jamacha Road or Highway 94, covering the neighborhoods around Cuyamaca College and Jamacha Valley alike. Same-day service is realistic most days, with emergencies prioritized on the schedule.
What does a copper pinhole leak look like before it becomes a flood?
Early clues include a faint water stain on drywall, blistering paint, a musty odor, or a water meter that creeps with every fixture off. Pinholes rarely announce themselves loudly, which is why we recommend acting on small signs quickly.
Is it better to fix each pinhole or repipe the whole house?
One leak in an otherwise sound system is worth a spot repair. Two or three within a couple of years usually means the pipe walls are failing generally, and a repipe becomes the cheaper path over any five-year window. We’ll show you the removed pipe sections so the decision is based on evidence.
