Apex homes inside town limits are served by the Town of Apex water system, which draws on Jordan Lake, so most residents have no well pump to worry about. Where a house near Apex still runs on a private well, a sudden loss of water usually traces to the pump, the pressure switch or the tank. Call the number on this page to be connected with a local plumber in Apex.
Apex water and the occasional well
The Town of Apex runs its own distribution system. Treatment happens at the Cary/Apex plant, which the two towns own jointly; Apex holds 12.9 million gallons a day of the plant's 56 MGD capacity, and the raw water comes from Jordan Lake. A home tied into that system has a meter, not a pump.
We could not find any Apex-specific data on private wells, so this page doesn't guess at a number. Where wells exist, they're most likely on rural parcels at the edges of the Apex area, including the part that crosses into Chatham County. Most of Apex's housing is recent (the median home was built in 2008), so in town the usual pressure complaints involve fixtures, a pressure-reducing valve or a leak rather than well equipment.
Repair or replace: the main well parts
| Part | Often repaired or adjusted | Usually replaced when |
|---|---|---|
| Pressure switch | Cleaning pitted contacts, resetting cut-in and cut-out | Contacts are burned or the switch chatters |
| Pressure tank | Recharging air on an older tank without a bladder | The bladder has split or the shell is rusting |
| Submersible pump | Rarely; wiring at the wellhead can be fixed | The motor has failed or output has dropped badly |
| Jet pump | Seals, impeller, priming problems | The motor is worn out or the housing has cracked |
| Check valve or control box | Capacitor or relay in the control box | The valve leaks back and the pump loses prime |
Signs it's the well system
- No water at any tap
- The pump starts and stops in quick bursts
- The pump's breaker keeps tripping
- Pressure fades in the middle of a shower and then comes back
- The pump runs when nothing is open
Seasonal patterns
Summer is when well systems get pushed hardest. Lawn watering, filling pools and long showers mean more pump starts per hour, and that's when a tired pressure switch or a tank that has lost its air shows itself. Thunderstorms bring a second risk: a nearby strike or power surge can damage the control box or the motor. In winter, any pump or piping in an unheated pump house or crawl space needs protection from freezing.
Work inside Apex that needs a permit goes through Town of Apex Building Inspections and Permitting, which requires permits even for same-size water and drain line replacement.
