In Four Oaks, the town collects wastewater and Johnston County treats it, so replacing a sewer line here means new pipe for the private lateral from your house to the town's line. About a third of homes predate 1980, and those older laterals are the most common candidates. Call the number on this page to be connected with a local plumber in Four Oaks.

Four Oaks sewer and housing
Johnston County's 2024 wastewater report says Four Oaks wastewater travels to the county treatment facility through force mains, interceptors and three pumping stations, and can also be pumped directly to Benson. The town maintains its collection lines; the private lateral from your house to that system is the owner's.
Four Oaks also runs its own building inspections instead of relying on Johnston County, with an in-house chief building inspector and permits handled by the town's planning, zoning and inspections office. A sewer replacement would be inspected locally before the trench is filled.
The housing mix is moderate. The median home was built in 1985 and about 35% predate 1980, according to ACS 2019-2023 estimates. Houses near the Four Oaks Commercial Historic District and older streets along Wellons Street (US 301) are where original clay or cast iron is likeliest. Homes from the 1980s onward generally have plastic lines.
Repair or replace?
| Situation | Spot repair | Full replacement |
|---|---|---|
| Damage location | One joint or one short section | Many joints along the run |
| Pipe age | Rest of line is sound | Old clay or cast iron throughout |
| Repair history | First problem | Patched before |
| Slope | Line is on grade | Long sag holding water |
If most of the right-hand column matches what the camera shows, replacement usually costs less over the life of the house than repeated repairs.
Signs to act on
- Recurring main-line clogs
- Gurgling in a toilet when the tub drains
- Odor outside near the foundation or cleanout
- A sunken line in the yard
- Roots on the cleaning cable
When to schedule
If a line is backing up now, clearing it comes first. Once a camera shows widespread damage, schedule the replacement in a dry stretch; it's easier on the yard. Root-damaged lines tend to get worse through the growing season, so waiting a year often means another backup first.
When you're ready, the call is simple. We connect you with an independent local plumber who serves Four Oaks; a camera inspection usually comes first, then a recommendation for repair or replacement and the method. Ask what restoration is included, since that varies more than the pipe work itself.
