Leak Detection in Cary, NC

Clues worth acting on

• A Cary Utilities bill that is noticeably higher than the same month last year
• The meter's leak indicator spinning when no one is using water
• A ceiling stain under an upstairs bathroom that keeps widening
• Hot spots on a floor, which can mean a hot water line is leaking underneath
• Pressure that seems weaker at every fixture, not just one
• Irrigation zones that leave puddles or soggy ground long after they shut off

How Cary's setup affects a leak

Cary generally owns the water line from the main to the meter, and the property owner typically owns the line from the meter to the house plus everything inside. A leak at the meter box or in the street is the town's to fix. A leak in the yard on the house side of the meter is yours.

The town reports no lead service lines in its system, but in its 2024 inventory about 6,800 of roughly 75,000 connections still had a segment of unknown material. If you're curious about your own line, that inventory is the place to start.

Most Cary homes date from the 1980s through the 2010s, with a median year built of 1999 and only about 12% built before 1980. That means fewer failing galvanized lines than in older towns, but plenty of homes now old enough for original supply hoses, water heater connectors and polybutylene-era fittings to give out. Cary water is chloraminated most of the year with a spring switch to chlorine, and chloramine is hard on rubber seals, so a toilet that refills on its own is a common find.

Many Cary yards also have irrigation systems, and the town requires annual backflow testing on residential irrigation devices. A cracked sprinkler line or a leaking assembly can account for a big share of an unexplained bill.

What changes the price

• Whether the leak is inside the house, under a slab, or in the yard
• How many methods are needed to confirm it
• How much finish material sits between the plumber and the pipe
• Whether you schedule the fix right away or separately
