Is it your water line or the town main?
Water reaches a Morrisville house through the Town of Cary's system. Cary's mains run under the street, and a service line connects each property to its meter. Where Cary's responsibility ends and yours begins depends on the property, so ask Cary before you assume.
| What you notice | Likely side | First step |
|---|---|---|
| Low pressure or no water on several houses on the street | Cary main or a shared problem | Call Cary at (919) 469-4000, the number it lists for callers outside its town limits |
| Pressure dropped at your house only and the dial moves with everything off | Your service line or a pipe inside | Close the home main, watch the dial again, then call us |
| Soft, wet or sunken ground between the meter and the house | Service line leak | Photograph it, do not dig and call us |
| Water rising out of the meter box itself | Possibly utility equipment | Report it to Cary at (919) 469-4000 |
What a main break looks like from a Morrisville kitchen
In January 2026, WRAL reported that an aging Cary main burst in two places on Northwest Cary Parkway and that about 120 homes lost water while crews repaired it. Cary maintains roughly 1,172 miles of water pipe. The report does not name Morrisville, though the same Cary system supplies it.
The lesson for your own line is about order. When water drops on your whole street, call Cary first and save the plumber for a problem on your side. When pressure returns, look under sinks and beside the water heater for fresh drips, since a sudden surge can find a weak joint.

Low water pressure: checks before you blame the line
Low pressure has several causes, and most are cheaper than a new service line. We separate them by testing, starting with where the weakness shows up.
Five checks that narrow it down
- Does the weak flow affect one fixture, one bathroom or the whole house? One fixture usually means a clogged aerator or a worn cartridge.
- Is the main valve fully open? A valve left partly closed after earlier work is a common culprit.
- Is only the hot side weak? That points to the water heater, not the service line.
- Does your home have a pressure regulator at the main? A failing one can drop pressure everywhere.
- Does pressure fall further when two fixtures run? That suggests a narrowed pipe or a partial blockage.
We attach a gauge to an outdoor hose bib and compare static pressure with pressure under flow. A big drop under flow means water is struggling through a restriction. If old steel pipe is the restriction, repiping addresses the cause.
Signs the buried line is failing
What owners notice first
- A meter dial that moves with the house valve closed.
- A wet, soft or sunken strip of ground between the meter and the house.
- A lawn stripe that stays green or boggy through dry weather.
- Muddy or discolored water right after pressure changes.
- A hissing or running sound near the entry point of the line.
Service line leaking right now
If a buried line is leaking right now
A broken service line can undermine soil, paving and a foundation edge if it runs unchecked.
Close the home main
Turn the house shutoff clockwise. If water still surfaces outside, the leak is ahead of that valve.
Do not dig
Digging blind risks other buried lines. Call 811, which NC 811 asks homeowners to do three working days before any digging.
Keep water away from the house
Divert surface water from the foundation with a hose or sandbags if it is safe to do so.
Call dispatch
Call (919) 944-7281 with your meter photo and a description of the wet area.
Repair, replace or go trenchless
| Approach | How it works | Fits when | Trade-off |
|---|---|---|---|
| Spot repair | Dig to the leak, cut out the damaged section and join new pipe with a coupling | One failure in a line that is otherwise in good shape | Another failure may follow along the same old pipe |
| Open trench replacement | Excavate the full route and lay a new line from the meter to the house | Long damaged runs or lines that cannot be pulled through | Lawn, drive or walkway restoration afterward |
| Trenchless replacement | Pull a new line through the old path from small pits at each end | Soil, depth and obstacles allow it | Not every site qualifies, and we say so after looking at the route |
What a replacement job involves
The same order applies whether the line is repaired or replaced.
- 01
Locate before digging
We call 811, which asks for three working days of notice, so marked utilities are known before a shovel goes in.
- 02
Check the permit
The Town of Morrisville plumbing permit page lists replacement of a plumbing system, so ask the Inspections Department at 919-463-6190 who pulls the permit.
- 03
Identify and replace
We identify the existing pipe material when it is exposed, then install new pipe sized for the house.
- 04
Pressure test and restore
The new line is tested before it is buried, and the trench or pits are backfilled and tidied.
Replacement work follows the 2024 North Carolina Plumbing Code, mandatory since July 1, 2025. We do not quote burial depth or pipe size from memory, because the Inspections Department confirms what applies to your job. Water main replacement in the street is Cary's work, not ours, and we will point you to Cary at (919) 469-4000 when that is the real problem.
What changes the price of water line repair
Service line jobs vary more than almost any other plumbing work, and you get a clear price before work starts.
Length of the line
The distance from the meter to the house sets how much pipe and digging is involved.
Surface above it
Lawn is simple to restore. Concrete, pavers and landscaping take more work.
Depth and soil
Deeper lines and rocky or tight soil slow the work.
Method
Spot repair, open trench and trenchless are three different jobs.
Obstacles
Trees, fences, drives and other buried utilities can change the route.
Home insurance policies vary on buried lines. Some cover sudden damage to the line and others exclude it, so call your insurer before work begins.
Permits and code for a service line
Replacing the line between the meter and the house falls under the 2024 North Carolina Plumbing Code, in force since July 1, 2025 and based on the 2021 International Plumbing Code (IPC). Where the utility's responsibility ends and yours begins is a Cary question, so ask Cary before you dig.
Call 811 before any excavation, and ask the Town of Morrisville Inspections Department at 919-463-6190 whether the replacement needs a permit.
Call (919) 944-7281 and tell us what the meter and the ground are doing. We answer all hours.
Questions we hear
Yes. Dispatch answers at night, on weekends and on holidays. Close the home main, note the meter and call (919) 944-7281. If your whole street lost water, call Cary at (919) 469-4000 first.
We cannot answer that from here, because it depends on the property. Ask Cary at (919) 469-4000 where its responsibility ends and yours starts. Take your meter photo with you.
No. A clogged aerator, a partly closed valve, a failing regulator or corroded steel pipe in the house can all do it. We test pressure and flow before suggesting any excavation.
No. Water mains belong to the Town of Cary, which reports and repairs them. We work from the meter to your house and inside your property.
A leak detection visit closes the house valve, watches the meter and traces the line with a locator and a listening sensor. That usually narrows the dig to a small area.
Not at first. Inside breaks show as a flood. A buried break shows as a meter that keeps turning, a wet yard or low pressure. Once located, a split section may be handled as burst pipe repair.
