, fewer connections and fittings are needed in a PEX installation.
 Non-corrodible. PEX, unlike copper, is not subject to corrosion from minerals or moisture.
 No fire risk during installation. The oldest and most common method for joining copper piping is to solder pieces together using a torch.  With an open flame there is always the risk of causing a fire in the surrounding structure, but PEX installation does not require a flame.
 Ability to merge new PEX with existing copper and PVC systems. Manufacturers make fittings allowing installers to join a copper pipe on one end with a PEX line at the other, as well as giving options to reduce or expand the diameter of the pipes.
 Longevity. The advantageous properties of PEX also make it a candidate for progressive replacement of metal and thermoplastic pipes, especially in long-life applications, because the expected lifetime of PEX pipes reaches 50 years. 
 Suitable for hot and cold pipes. A convenient arrangement is to use color-coding to lessen the possibility of confusion. Typically, red PEX tubing is used for hot water while blue PEX tubing is used for cold water.
 Less likely to burst from freezing. The general position is that PEX plastic materials are slower to burst than copper or PVC pipes, but that they will burst eventually since freezing causes water to expand. One account suggested that PEX water-filled pipes, frozen over time, will swell and tear; in contrast, copper pipe "rips" and PVC "shatters". Home expert Steve Maxwell suggested in 2007 that PEX water-filled pipes could endure "five or six freeze-thaw cycles without splitting" while copper would split apart promptly on the first freeze. In new unheated seasonal homes, it is still recommended to drain pipes during an unheated cold season or take other measures to prevent pipes from bursting because of the cold. In new construction, it is recommended that all water pipes be sloped slightly to permit drainage, if necessary.
 Environmental benefits. One account suggested that PEX used in radiant heating was better for the environment than copper, although it noted that the pipes were based on petroleum products.
 Pipe insulation possible. Conventional foam wrap insulation materials can be added to PEX piping to keep hot water hot, and cold water cold, and prevent freezing, if necessary.

One account suggested that PEX body of water - filled pipe, frozen over clock time, will swell and bust; in contrast, copper pipe " rips " and PVC " shatters ". Home expert Steve Maxwell suggested in 2007 that PEX body of water - filled pipe could endure " five or six freeze - thaw cycles without splitting " while copper would split aside promptly on the first freeze. In new unheated seasonal base, it is still recommended to drain pipes during an unheated cold season or take other measures to prevent pipe from bursting because of the cold.
