Morrisville's water comes from the Town of Cary, which generally owns the line up to the meter, so a leak between the meter and your house is typically a private repair. A plumber can test the system and find the leak without guesswork. Call the number on this page to be connected with a local plumber in Morrisville.

Morrisville homes and water
Morrisville sits between Raleigh and Durham next to RTP and RDU, and its housing is almost all recent. About 76% of homes were built since 2000, the median dates to 2007, and fewer than 3% predate 1980. Old corroded pipe is rarely the issue. Leaks here usually start at PEX fittings, supply hoses, water heater connections and irrigation systems.
Water and sewer come from Cary, so Cary's rules apply. Cary generally owns the line from the main to the meter, and the property owner typically owns the line from the meter to the house plus everything inside. Cary reports no lead service lines in its system. In a home built on a slab or in an attached townhome, a leak can travel along a floor or show up in a neighboring room, so the wet spot isn't always right above the pipe that failed.
What to do now
- Stop the water at the main shutoff if a leak is spreading.
- Run a meter test with all fixtures and the irrigation controller off.
- Isolate irrigation. Close the irrigation shutoff and test again to see if the leak is outdoors.
- Check the usual suspects: toilets (dye test), the water heater pan, under sinks and behind the washer and refrigerator.
- Report public-side leaks at the meter or in the street to Cary.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Bill rises when sprinklers run | Irrigation line, head or backflow device |
| Toilet refills by itself | Worn flapper or fill valve |
| Ceiling stain under a bath | Supply fitting, tub or shower connection |
| Warm floor area | Hot water line leak under the slab |
| Water near the fridge | Ice maker line |
What affects the cost
- Inside the walls, under the slab, or in the yard
- Irrigation involvement
- How much finish material has to be opened and replaced
- Same-visit repair or not
All Cary water customers with irrigation must have a backflow device tested every year by a certified tester. For repairs that need a permit, the Town of Morrisville Inspections Department issues plumbing permits. Cary's water is chloraminated most of the year, which can shorten the life of toilet flappers.
