HOME CARE · SEWER LINES & LATERALS
Sewer Lines & Laterals
This is the least glamorous system in the house and the most expensive surprise in it. A few hundred dollars of camera every few years is the cheapest insurance in homeownership. The only way to know what you own is to look at it.
General guidance for typical Portland-area homes. Your home’s systems, age, and site may differ. When in doubt, ask. Electrical, gas, roofing work above the first story, and sewer repairs belong to licensed professionals.
TASK SCHEDULE
| TASK | FREQUENCY |
|---|---|
| Camera scope | At purchase, always; then every 3–5 years for older homes with mature trees |
| Root treatment/cleaning if roots present | Per scope findings, often yearly |
ERA NOTES
Many Portland-era laterals are concrete or clay with joints that roots find, and some mid-century homes carry bituminous-fiber (‘Orangeburg’-type) pipe that deforms with age. A scope is the only way to know what you own. This is the least glamorous system in the house and the most expensive surprise in it. For older homes: the Craftsman bungalow era (1905–1930) and MCM era (1945–1970s) both have elevated lateral risk. A scope at purchase is not optional.
