PEX-A vs. PEX-B Installation in Chesterfield
We offer installation for both PEX-A and PEX-B piping and understand the different advantages of each. PEX-A, often preferred for its flexibility and ability to recover from minor kinks, uses expansion fittings. PEX-B is more rigid but also very durable, usually using crimp or compression fittings. Our plumbers in Chesterfield can help you decide which type of PEX suits your project, considering factors like budget and application.
PEX-B Crimp and Clamp Systems in Chesterfield
PEX-B is stiffer and more affordable, and it is joined with copper crimp rings or stainless steel cinch clamps over brass or poly fittings. It is a solid option for smaller projects and budget-conscious repipes. Brands like Viega, Zurn and SharkBite offer dependable PEX-B systems. We use a go/no-go gauge on every crimp to verify a proper seal.

Beyond residential work, FGV Plumbing also provides commercial PEX pipe installation for businesses in Chesterfield.

Frequently Asked Questions About PEX Pipe Installation in Chesterfield
A whole-home PEX repipe typically costs $4,500 to $12,000 depending on home size, bathroom count and access. Smaller jobs like a single bathroom remodel rough-in usually run $800 to $2,500.
Whole-home repipes usually require a plumbing permit and inspection. We handle the permit process as part of the project.
PEX can be used for outdoor applications like irrigation lines or outdoor spigots, but it needs to be protected from direct UV light, which can break down the material over time. When used outdoors, PEX should consistently be buried or otherwise shielded.
Yes, for significant plumbing work like a full home repipe or new water line installation in Chesterfield, a plumbing permit is typically required. FGV Plumbing handles all necessary permits and makes sure our work complies with local building codes and inspections.
PEX is well suited for a wide range of climates because of its flexibility and resistance to freezing. Rapid swings from mild to freezing weather stress pipes and fittings, especially in older homes. 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 Chesterfield.
A full home PEX repipe for an average-sized home in Chesterfield typically takes 3 to 5 days. Smaller projects or single-line replacements can often be completed in a single day. We aim to minimize disruption and communicate timelines clearly.
Properly installed PEX is expected to last many decades. Manufacturers commonly offer 25 year warranties when their pipe and fittings are used together.
Most whole-home PEX repipes take two to four days. Larger homes or tight attic access can take a bit longer.
