South Durham and Research Triangle Park come first
Our base on Chapel Hill Road in Morrisville sits closer to the southern edge of Durham than to downtown. A routing estimate puts the Southpoint area at about 12 miles and 20 minutes without traffic, and downtown Durham at about 16 miles and 26 minutes. Rush hour on I-40, NC 54 and NC 147 stretches both numbers, so treat them as planning figures and not promises.
That geography is why ZIP 27713 leads this page. It is a south Durham ZIP and The Streets at Southpoint, at 6910 Fayetteville Road, sits inside it. If your address is near Southpoint, the 27713 side of Research Triangle Park, or the NC 54 corridor, say so when you call so dispatch can place you correctly.
| ZIP | What we can say about it | What to tell dispatch |
|---|---|---|
| 27713 | South Durham. The Streets at Southpoint is in this ZIP. | The nearest cross street or the shopping center you can see |
| 27707 | A residential Durham ZIP with a large population. Check the exact boundary with the USPS ZIP lookup. | Your full street address so we can confirm the route |
| 27709 | The ZIP used for Research Triangle Park mail. Many buildings there are offices and labs. | Whether the building is commercial and who manages it |
Durham water is not Morrisville water
Durham's drinking water comes from Lake Michie and the Little River Reservoir, according to the city's water quality page, and the City of Durham runs the mains under your street. Morrisville is different. Our home town buys its water from the Town of Cary, so we cannot assume that what we know about a Morrisville service line applies a few miles up the road.
The practical rule is simple. If water is out or weak on the whole block, the problem is probably the city main and the number to call is 919-560-4344, which the city lists for water main breaks and sewer overflows. If only your house is affected, or you can see water pooling at your own meter box, that is the part we fix. Leak detection sorts out which side of the meter the water is on.
If you have a burst pipe or active leak in Durham
Before we arrive
Four steps limit the damage in the first ten minutes. They are the same whether the leak is a burst supply line or a failed water heater.
Close the main valve
Look for the shutoff where the line enters the house, often by the water heater or on a front basement or garage wall, and turn it clockwise.
Kill power near water
If water reaches outlets, appliances or a panel, switch the breaker off from a dry spot. Never wade into standing water to reach it.
Clear the area
Move people, pets and valuables away from the wet floor and open the nearest drain or door if water is rising.
Call the 24/7 line
Dial (919) 944-7281 and tell dispatch your ZIP, what you shut off and where the water is coming from.
Who to call first in Durham
| Situation | First call | Why |
|---|---|---|
| No water or low pressure on the whole street | City of Durham, 919-560-4344 | The city owns the main. The line answers outside office hours through an on-call service. |
| Sewage backing up in several fixtures | Us first, then the city if the street main is full | Sewer line cleaning shows whether the blockage is on your side of the property line. |
| One fixture, one pipe or the water heater is leaking | Our 24/7 line | It is inside your property, so it is a plumbing repair and not a utility problem. |
| Not sure if you need a permit | City-County Building and Safety, 919-560-4144 | Permit rules for Durham work come from Durham. |
Permits for Durham plumbing work
Durham's City-County Building and Safety Department handles permits and inspections for the city and the county. Its plumbing permit page says a permit is required for new construction, additions, alterations, replacements and all private utilities, meaning sewer and water services. Backflow device installations need a separate permit from Durham's Cross Connection Control Department.
In practice that means a water heater swap or a service line replacement in Durham is a permitted job, and the permit applicant has to schedule the inspection. Ask any plumber, including us, who pulls the permit before the work starts. For Durham addresses the department's office is at 101 City Hall Plaza and its phone is 919-560-4144.
What the 2026 main breaks mean for your house
News reporting in September 2026 counted more than 141 water main breaks in Durham so far that year, and the city moved to Stage 2 water restrictions in June 2026 during a drought. Those are city-side events, but they change how homeowners should watch their own plumbing.
A main break can drop pressure and then restore it with a surge. After a surge, check under sinks, behind the water heater and around the meter for new drips. A meter that keeps turning with every tap closed means a leak somewhere past the meter. That is the moment to call about water line repair or a leak survey instead of waiting for the bill.
Sewers, plants and backups on the Durham side
The City of Durham operates about 1,100 miles of sewer line and two water reclamation plants, North Durham and South Durham. Durham County runs the Triangle plant that serves Research Triangle Park. The plant that handles your waste depends on where you live, but the clog that backs up your tub is almost always in your own line.
If a toilet gurgles when the washer drains, or two floor drains back up together, the blockage sits in the main drain. Roots, grease and wipes cause most of them. A cable machine or hydro jetting clears it, and a camera run afterwards shows whether the pipe is damaged. Call the city only if the cleanout in your yard is full and the street manhole is overflowing.
Dispatch answers every hour of every day, including nights, weekends and holidays.
The services Durham homeowners ask about most
Most calls from the south Durham side fall into a short list. Drain cleaning leads, followed by a failing water heater, a leaking toilet or faucet, and water showing up where it should not. If your water heater is leaking from the tank, the usual next step is a replacement, because a tank that has rusted through cannot be patched.
We do not run separate pages for every Triangle town. Raleigh, Cary and Apex all have their own coverage, so see the full list of towns we serve and call if your address is not on it. We will tell you honestly whether we can reach you.
Questions we hear
We dispatch to Durham addresses in 27713, 27707 and 27709 first. 27713 runs through south Durham around The Streets at Southpoint, 27709 is the Research Triangle Park mail ZIP, and 27707 is a large residential ZIP that you can check against the USPS lookup. Other Durham ZIPs such as 27703, 27704 and 27705 may be reachable too, so call (919) 944-7281 and give your address.
Yes. The 24/7 line answers all day and night, including holidays, and dispatch sends a licensed plumber from Morrisville. Tell the dispatcher your address, what you shut off and whether water is still flowing.
The City of Durham lists 919-560-4344 for water main breaks and sewer overflows. It is staffed during weekday office hours and answered by an on-call service the rest of the time. Call us for leaks inside your own property.
Durham's permit page lists replacements among the work that needs a permit, so plan on one. The City-County Building and Safety Department at 919-560-4144 can confirm what applies to your address.
No. Our base is at 9954 Chapel Hill Road in Morrisville, and we send plumbers north into Durham. We say so plainly because it affects arrival time, and dispatch will give you a realistic window when you call.
Often yes. A meter test shows whether water is leaving your side of the meter. If it is not, the problem is the city main, and a leak detection visit would not help.
