WINTERIZE A BUILDING
This article describes the pros and cons of using copper or plastic piping in buildings. We explain the advantages and possible downsides of choosing one or the other (plastic piping or copper piping for water supply or drains). The question of which is better, copper or plastic piping, copper or PEX, copper or ABS, or copper and PVC or CPVC piping has answers but the results may not be as unambiguous as one imagines. Each piping material & piping connector or fitting system has both its advantages and its concerns.

Some questions have been raised about the chemicals used in the adhesives used to join sections of piping, and the toxic gases given off from plastic piping during a fire.
Polyethylene (PE) and polyvinyl chloride (PVC) are only suitable for waste, underground water service pipes or cold water piping systems.
Our photographs of plastic water supply piping connections just below show a new water main (below left) and building supply pipe being connected to copper piping entering a building (below right) in San Miguel de Allende, Guanajuato, Mexico in 2010.

What About the Relative Safety of Copper Piping vs. PEX Piping in Buildings?
Details comparing the concerns, issues, codes, standards, features & questions about possible health concerns where PEX piping is used are found at PEX vs. Copper Piping, safety. Excerpts from that article are below.
Pex vs. Copper Water Supply Piping - which is better?
Question: my daughter is doing extensive renovations on her house and the question has come up whether to use PEX or copper in the plumbing. I did a google search and the informations is conflicted. Do you have knowledge of, and opinions about, this controversy? - Elisha Fisch, New York 2/17/2013
Copper has been around a long time. We recently chose PEX for both water suppy and for a hot water heating line in an addition and so far have been happy with the results.
Our PEX tubing photo at left shows its use in new construction completed in a New York structure in 2012.
You can see the ease of bending radius in these piping runs of both hot (red) and cold (blue) water supply lines.
What follows is an OPINION based on field experience as a builder, renovator & inspector:
PEX water supply piping offers some advantages over copper sweat-fitting piping installation
Our PEX tubing photo at left illustrates an older PEX piping product installed in a Haddonfield New Jersey Home.
