(More rigid piping materials are susceptible to water hammer noise, which can be heard throughout a structure.) The majority of PEX tubing is manufactured per the following standards: 1 When used in piping, the material is especially quiet, thanks to its flexibility and ability to absorb pressure surges. PEX is also resistant to notching and abrasion, and helps minimize noise transmission. Without special treatments or additives, its water maintains consistent pressure and flow over long periods.

scaling) when used with both hard and soft water. PEX pipe’s smooth interior walls also make it resistant to mineral buildup (i.e. Polyethylene, on the other hand, is a dielectric material-it can be used as an insulating material for electrical conductors-and its role as a non-conductor makes corrosion a scientific impossibility. Corrosion is an electrolytic process, requiring the presence of electrically conductive materials. By its very nature, PEX plumbing pipe neither pits nor corrodes. These qualities could make rusty plumbing pipes a thing of the past for many homeowners. PEX pipes, also known as cross-linked polyethylene pipes, rely on plastics structurally modified for impact/tensile strengths, decreased shrinkage, high temperature/pressure performance, and resistance against creep, chemicals, and cracks.
