The short version
Pipe replacement averages $1,246[1] in the U.S. Most jobs cost $372 to $2,120[1][1]. A whole-house repipe costs much more.
Small leaks add up. The EPA says leaks in an average home can waste more than 9,300[2] gallons a year[2].

Small leak or big job?
Pipe problems come in two sizes. Knowing which one you have saves money.
- One leak. A plumber fixes one spot. A pipe leak fix starts near $150[1].
- Many leaks, or very old pipes. The plumber may suggest new pipes for the whole home. That is called a repipe. It costs $1,500 to $15,000[1].
Most people start with a fix. A repipe makes sense when leaks keep coming back.
Clues to watch for
- A water bill that jumps with no reason.
- Wet spots or stains on walls or ceilings.
- A musty smell under sinks.
- The sound of running water when every tap is off.
- Brown or rusty water from cold taps.
Small drips add up. The EPA says a faucet dripping once a second can waste more than 3,000[2] gallons a year[2].
Old homes and lead
Homes built before 1986[4] are more likely to have lead pipes[4]. If your home is that old, ask your water company about testing. Ask your plumber what your pipes are made of.
In Florida, look up a plumber's license on the state DBPR site[5] before you hire.
What to do first when you find a leak
- Turn off the water at the main shut-off, or at the valve under the sink.
- Move things that can get wet out of the way.
- Take photos for your records and your insurance.
- Call a plumber and tell them what you saw.
Pipe types in plain words
- Copper is a stiff metal pipe. Home inspectors list copper water lines at about 70 years[3][3].
- PEX is a bendy plastic tube. It can snake through walls with fewer cuts.
- CPVC is a stiff, cream-colored plastic pipe.
Your plumber can tell you which one fits your home and your budget.

Check your water bill in winter. The EPA says a family of four using more than 12,000[2] gallons a month may have serious leaks.
Does a leak fix include fixing the wall?
Often not. Drywall repair after pipe work costs $300[1] to $800[1]. Ask before work starts.
