Apex homes are some of the newest in Wake County, so a hidden leak here is usually a fitting, a supply connection or an irrigation line rather than worn-out pipe. A plumber can isolate sections of the system and pinpoint the source before opening anything. Call the number on this page to be connected with a local plumber in Apex.
What's different about leaks in Apex
The median Apex home was built in 2008, and fewer than 4% of homes predate 1980. The town has also reported finding no lead or galvanized service lines that need replacement. Corroded old pipe, the usual story in older towns, is rarely the problem here. Leaks in Apex tend to start at connections: crimp and push fittings on PEX, braided supply hoses, water heater and ice maker lines, and the irrigation systems that many Apex lots have.
Apex runs its own water distribution system, with water from Jordan Lake treated at the plant it shares with Cary. The town owns and maintains the public side of the service line, and the property owner owns and maintains the private side. If a leak shows up at the meter box or in the street, that goes to the town.
Irrigation deserves special attention. Apex requires lawn irrigation to have a reduced pressure backflow assembly mounted at least 12 inches above grade between the meter and the first sprinkler head, tested every year. Those assemblies, and the buried lines beyond them, are common leak points.
Where the leak is, and what usually happens next
| Leak location | How it's usually found | Typical next step |
|---|---|---|
| Supply hose or fixture connection | Visual check, moisture meter | Replace hose or fitting |
| Line inside a wall or ceiling | Pressure isolation, thermal imaging | Small access opening and repair |
| Line under a slab | Acoustic listening, pressure test | Spot repair or reroute |
| Yard service line or irrigation | Meter test, ground listening | Dig and repair the section |
Signs to watch for
- A bill from the Town of Apex that's out of line with past months
- The meter's flow indicator turning with all fixtures off
- A warm patch on a tile or concrete floor
- Water in the water heater pan or around the base of a toilet
- One irrigation zone with weak spray or soggy turf
Timing and permits
Irrigation leaks tend to surface in late spring and summer, when systems run most. Each year Apex also switches from chloramine to chlorine for several weeks in late winter and early spring, which can change how the water tastes and smells but doesn't cause leaks. Apex requires a permit even for same-size water line and plumbing fixture replacement, so a plumber will factor that into the repair plan.
