If you have a home that is more than 30 years old, it’s very possible that the plumbing system was constructed with galvanized pipe. Although galvanized pipe has been previously used to transport drinking water, now is is more often used for sewage and irrigation plumbing. Most of these pipes contain lead, which make them unsuitable for drinking water. However, galvanized pipes can be replaced with newer lead-free models, and may still be used for non-drinking water plumbing.

Benefits of Galvanized Pipe


Galvanized pipe is coated with zinc and metal. This makes them more durable than older pipes which were crafted from steel or iron. These pipes also have added protection, because the coating of zinc prevents issues with corrosion.

Lifespan of Galvanized Pipe


Galvanized pipes are very durable, often lasting 40 years or longer. However, if your water contains high quantities of minerals, the life expectancy may decrease. Hard water, which is prevalent in certain regions like California, may decrease the longevity of galvanized pipes. Before installing galvanized pipe, it’s helpful to talk with a plumber. A plumber can help test your water to determine if this type of plumbing is the best fit for your home.

Cost of Galvanized Pipe

The cost of galvanized pipe will vary depending on the size of the job and your geographic location, but you can expect to pay a minimum of $2,000. In addition, you’ll need to budget for drywall damage caused by gaining access to the plumbing. If you hire a plumber, his or her labor rate will depend on where the pipes are located. For example, if the plumber has to dig underground, it will be more expensive than replacing plumbing in the attic.

Installing Galvanized Pipe


As with any plumbing issue, if you don’t have experience replacing galvanized pipes, it’s worth hiring a professional. Tackling this project yourself can result in additional costs if done incorrectly. A plumber can complete the job quicker and save you money in property damage from a plumbing job gone bad.

When hiring a plumber, it’s helpful to get multiple bids. This will give you a price range for your specific geographic area. Once a plumber has been selected, create a detailed contract including work to be completed, pricing information and completion date.
