Whole-Home Repiping in Charlotte, NC: Old Galvanized Pipe
Whole-home repiping in Charlotte, NC
Weak pressure all over an older house often comes from the pipe itself. In old galvanized pipe, rust and scale build up inside. They can significantly restrict water flow, and a new aerator or showerhead does not change that. Galvanized steel is strong but lasts only about 50 years.
Tell us how old the house is and what pipe you can see at the water heater or under a sink. We check whether a local plumber can take the job. The effort depends mostly on how the walls and floors are finished.
One run or the whole house
A single failed length in otherwise sound pipe is a spot replacement. Whole-home repiping is for a house where the old pipe is failing throughout: low pressure on several floors, rusty water, repeat leaks in different rooms. It is a planned job, not an emergency. If one leak is the problem right now, start with leak detection.
What the house was built with is the first clue. Most homes built since the mid-1970s have plastic pipe. Older houses in neighborhoods like Dilworth and Myers Park can still carry galvanized supply lines unless a renovation replaced them. See which Charlotte–Mecklenburg neighborhoods have the oldest single-family homes.
Repiping changes the plumbing system, so it is permitted and inspected by Mecklenburg County Code Enforcement.
| Path | When it applies | What drives effort |
|---|---|---|
| Spot replacement | One failed length | Access, finish |
| Whole-home | Old pipe failing throughout | Room count, finishes |
| Drain clog | Slow drains, not weak supply | Cable or jet, not new supply pipe |
Do I need whole-home repiping or one pipe replacement?
Only when the old pipe is failing throughout the house. One failed length is a spot replacement.
Why is water pressure low on the second floor?
In older houses, scale inside galvanized pipe narrows the pipe until upstairs fixtures run weak. A plumber checks the pipe before choosing between one run and the whole house. Slow drains are a different problem; see drain cleaning.
