What makes these homes different
The typical North Orange County resale is a single-story slab-on-grade house from the 1950s, 60s or 70s. The supply lines may be original galvanized, copper, or a partial repipe; the sewer lateral is often clay or cast iron; and the yard may have trees older than the house. None of that is a reason to walk away, but each one is worth understanding before you set your budget.
Inspection checklist
- Order a sewer lateral camera inspection and get the video
- Identify supply pipe material at the water heater, hose bibs and under sinks
- Run several fixtures together and watch pressure
- Check for brown water after the house has sat unused
- Read the meter with everything off to check for hidden leaks
- Note the water heater's age, seismic strapping, venting and relief valve drain
- Look for warm floor spots and stains that suggest past slab leaks
- Ask the seller for records of repipes, slab leak repairs or sewer work
- Ask whether permits were pulled for any past plumbing work; check with the city
- Look at gas appliance connectors and the age of the gas piping
What you might find and what it means

|---|---|---|
| Roots at several lateral joints | Ongoing backups likely | Get lining or replacement quotes |
| Galvanized supply throughout | Repipe likely in the future | Get repipe quotes |
| Water heater at or past typical life | Replacement soon | Budget for it; check strapping and venting |
| Meter moves with everything off | An active leak | Arrange leak detection before closing |
| Previous slab leak repairs | Other under-slab lines are the same age | Ask about reroutes or repipe |

Common questions
Is a sewer camera inspection worth it for a newer house?
It is most valuable for older homes with clay or cast-iron laterals, but any house with mature trees or a history of backups benefits.
Can I tell pipe material myself?
Often. Galvanized is dull gray with threaded fittings; copper is reddish-brown with soldered joints; PEX is colored plastic tubing.
Should I ask for repairs or a credit?
That is a negotiation question for you and your agent; written plumbing quotes give you numbers to work with.
