Copper pipes have become the standard for most new home construction - replacing galvanized steel pipes.
Reliability, corrosion resistance, and no mineral build-up over time are the main reasons for using copper pipes.
Typical Cost of Replacing Old Pipes with New Copper Pipes:
- This could run anywhere from under $100 to more than $10,000
Low-End Cost Estimate:
- If you simply need to replace a leaking pipe under a sink, this could conceivably cost less than $100-$200, especially if you can do the job yourself.
High-End Cost Estimate:
- A complete tear-out and repipe using copper pipes could easily cost more than $10,000 or more in a moderate-sized home. However, the cost of a repipe may be significantly less than the cumulative costs of leaks, water damage and higher water bills.
What to Expect:
- It may be possible to save some money on the job by doing it yourself if you have the know-how and tools. Copper pipe is generally available from plumbing supply houses for an average of $5 per foot, and other parts can also be easily obtained.
- Copper pipe is not recommended for areas with highly acidic water (6.5 pH or less) as corrosion risks are markedly greater.
- Copper pipes laid underground may need to be wrapped in a protective layer to prevent corrosion caused by contact with certain elements that may be present in the soil under your home.
- Copper pipes used for waste are at risk of corrosion issues caused by ammonia reacting with the copper.
- If it is necessary to tear out old pipes running through walls, this may incur an additional cost to replace drywall and repaint the walls once the new pipes have been installed.
- If you're replacing galvanized pipe in a house that was built before 1975, an asbestos inspection may be required before any work begins.
