PEX is a good fit for a wide range of climates because of its flexibility and resistance to freezing. Water heaters face heavy demand in winter, when incoming water is cold and families use more hot water. While rigid pipes can burst when water freezes, PEX can expand and contract, greatly lowering the risk of burst pipes during cold snaps. It also performs well in high temperatures, making it a reliable choice year-round in O'Fallon.
Small repairs are possible for handy homeowners, but a full repipe requires proper sizing, support spacing and code compliance. Mistakes behind walls can cause hidden leaks and failed inspections.
PEX offers several advantages over copper, including lower material and installation costs, greater flexibility and resistance to corrosion and freezing. Unlike copper, PEX does not form pinhole leaks over time due to water chemistry, making it a more durable choice for many O'Fallon homes. It also cuts down on water hammer noise.
FGV Plumbing stands behind our PEX pipe installations with a comprehensive warranty on both labor and materials. Specific warranty details will be provided with your estimate, but you can be confident your new PEX system is installed correctly and will perform reliably for years to come in your O'Fallon home.
PEX must be protected from sunlight because UV light breaks down it. Outdoors it needs to be buried, sleeved or completely covered.
