The Town of Smithfield treats its own Neuse River water, so homes on town lines don't have a well pump. Outlying 27577 homes may be on Johnston County water or private wells, and on a well the usual causes of lost water are the pump, the pressure switch and the tank. Call the number on this page to be connected with a local plumber in Smithfield.
Who supplies water around Smithfield?
Inside town, the Town of Smithfield runs its own water treatment plant on North 2nd Street, drawing from the Neuse River with a 24-million-gallon off-stream reservoir. A separate district called Smithfield South gets its water from Johnston County Utilities. Beyond those systems, outlying parts of the 27577 ZIP may be on county water or private wells; no count exists. If you don't get a water bill, you're almost certainly on a well.
Why is my pressure low if I'm on town water?
About 65% of Smithfield homes were built before 1980, and older houses often have galvanized supply pipe that narrows inside as it corrodes. Add an aging service line, a stuck main valve or a slow leak, and pressure can sag across the house with no pump anywhere in the picture. A plumber can measure pressure at the hose bib and work inward to find the restriction.
What usually breaks on a well near Smithfield?
Most failures come from a short list of parts:
- Pressure switch. Its contacts burn and pit with years of starts; the pump stalls or chatters.
- Pressure tank. Lost air or a torn bladder causes rapid cycling and pulsing pressure.
- Control box. On many submersible systems, a failed capacitor or relay keeps the motor from starting.
- Pump and drop pipe. A worn pump or a split pipe means weak or no flow, and the pump has to come up.
- Check valve. If it leaks, water drains back down the well and the pump has to work harder.
Older well systems on rural lots around town may have several tired parts at once, which is worth knowing before deciding to fix just one. If the pump won't shut off, kill its breaker until the plumber arrives.
A local note
Johnston County Building Inspections handles building permit inspections for the Town of Smithfield under contract, and the town's planning office issues the zoning permit first. For well homes outside town, the plumber will confirm whether the job needs a permit and which office issues it. If you're replacing a pump on an older rural system, ask about the tank and check valve too, since a new pump paired with a failing tank won't last as long as it should.
