What’s the Average Lifespan of Bathroom Supply Lines?

The materials out of which pipes are made determine the average lifespan of supply lines at a house in Oklahoma City, OK. Learning more about the longevity of common plumbing materials and causes of supply line damage can help homeowners make informed home improvement decisions.

Metal Lines Last Longer Than 70 Years
Supply line made out of metal can last anywhere from 70 up to 100 years depending on the material. All of the following pipe materials are used in residential plumbing:

• Cast iron
• Copper
• Galvanized Steel

Cast iron pipes are very thick and capable of withstanding high levels of water pressure. Copper pipes are more costly than galvanized steel, and though pipes of this material are relatively common, corrosion and metal contamination may become a factor over time.

Galvanized steel supply lines are coated in zinc to resist corrosion, but this layer wears down over time and steel pipes then run a risk of supply line damage. Any pipes you choose should provide years of reliable service. Avoid metals such as brass, which can leach lead into water.

Plastic Lines Last 25-40 Years
The most popular type of plastic supply line currently in use is Polyvinyl Chloride. This pipe material does not last as long as metal pipes but poses no risk of corrosion that contaminates water and degrades its quality. Pipes made of PVC and cPVC are more durable than polybutylene pipes that can break down and cause a bathroom leak in just 10 to 15 years.

Connections, flow, hardware and other factors may affect the longevity of a pipe and the risk of a supply line leak or other supply line damage. A homeowner may choose to get a replacement line in the same material as other supply lines in a structure or select a plastic or metal line to meet the specific needs of a household in Oklahoma City, OK.
