Once you determine you need a repipe, you’ll need to decide what material to use for your replacement plumbing system. Today there are basically three options – copper, CPVC, and PEX – and each comes with its own pros and cons. Many plumbers have their own preferences and will almost always recommend going with their favorite building material. 

Getting a good understanding of each type of pipe will help make an informed decision. If you like the sound of PEX pipes, for example, you might want to seek a certified plumber who specializes in PEX repiping.  

Copper Pipes

Copper pipes are the oldest piping system currently in use. Many plumbers and builders swear by copper pipes because they’re a tried and true material. It’s considered the gold standard in home plumbing systems, and they can last 75-100 years. There’s been a trend lately to use alternative materials like PEX and CPVC in new constructions and remodels. 

Pros:

More durable and longer lasting than PEX pipes

Won’t corrode like galvanized steel pipes

Don’t harbor bacteria or other contaminants

Temperature resistant

Has been used for decades and is a proven, reliable pipe material

Cons:

Copper pipes can burst or leak if they freeze

Are more expensive than PEX pipe/PVC

Installation is labor intensive, and therefore more labor cost

Are vulnerable to acidic water, potentially leading to pinhole leaks. 

Need to be insulated. 

Are generally louder than PEX pipes. Water hammer is a common complaint with copper pipes. 

Require larger sections of drywall to be removed during installation.

Require soldering with an open flame, which could potentially be hazardous to an existing home.  

CPVC (Chlorinated polyvinyl chloride) Pipes 

CPVC pipes are common in repipes and remodels. They started showing up on the market in the 1960s and have been steadily gaining popularity. It’s easier to work with than copper pipes and is well-suited for installation in an existing structure. They might not last as long as copper pipes, but they should give you at least 50 years of reliable plumbing. 

Pros:

Chlorinated PVC pipes are safe for transporting drinking water. 

Can be used to transport hot water

A cheaper alternative to copper pipes.

Are resistant to acidity and other chemicals in the water.  

Cons:

More expensive than PVC pipes, but has more versatility. 

Can crack during earthquakes

PEX (Cross-linked polyethylene) Pipes

PEX is the newest piping material currently in use. It started being used in new European construction, before gaining traction in the United States in the late 90s and early 2000s. PEX is versatile, flexible, and easy to work with, making it a favorite for modern-day builders.

Pros:

More cost-effective than copper pipes

Flexible material means its quieter than copper pipes

Flexibility makes PEX pipes easier to install, as they can be fed around bends in walls

Flexibility also eliminates the need for joint fittings, which can be a common source of leaks

Environmentally friendly

Less likely to crack or burst during freezing conditions

Naturally insulated, which helps against thermal loss 

Great option if your home is built on a concrete slab foundation  

Can be installed using smaller openings in drywall due to its flexibility 

Cons:

Less durable than copper pipes

Relatively new to the plumbing scene; the long-term prospects of PEX piping are still unknown

Will degrade if materials are not stored properly shielded from the sun.
