PEX-A vs. PEX-B Installation in Sammamish
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, typically using crimp or compression fittings. Our experts in Sammamish can help you decide which type of PEX suits your project, considering factors like budget and application.
PEX-B Crimp and Clamp Systems in Sammamish
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 good 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 confirm a proper seal.
PEX-A, PEX-B, and PEX-C Systems in Sammamish, WA
FHN Plumbing is knowledgeable in installing all types of PEX piping, including PEX-A, PEX-B and PEX-C, each with distinct properties for specific applications. We help you choose the best PEX type for your home's needs and budget in Sammamish, WA. Our expertise ensures the correct PEX material and fitting method, whether it is expansion for PEX-A or crimp and clamp for PEX-B and PEX-C, for a secure and lasting system.

Polybutylene Replacement With PEX in Sammamish, WA
Gray polybutylene pipe was common in homes built from the late 1970s through the mid 1990s and is notorious for sudden failures. Chlorine in municipal water breaks down the plastic and its fittings over time. Plenty of insurers now ask about polybutylene when writing a policy. Replacing it with PEX removes that risk and can make your home easier to sell and insure.

Frequently Asked Questions About PEX Pipe Installation in Sammamish
The cost of PEX pipe installation in Sammamish can range from $2,500 to $15,000 or more, based on the size of your home, accessibility and whether it is a full repipe or a partial replacement. Minor repairs might be a few hundred dollars. We provide a detailed quote after an on-site assessment.
FHN Plumbing stands behind our PEX pipe installations with a full 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 Sammamish home.
PEX is a good fit for a wide range of climates because of its flexibility and resistance to freezing. Washington has two very different climates, with long, wet and mild seasons in the west and hot, dry summers and cold winters in the east. While rigid pipes can burst when water freezes, PEX can expand and contract, significantly reducing the risk of burst pipes during cold snaps. It also performs well in high temperatures, making it a reliable choice year-round in Sammamish.
Whole-home repipes typically require a plumbing permit and inspection. We handle the permit process as part of the job.
Most whole-home PEX repipes take two to four days. Larger homes or difficult attic access can take a bit longer.
Properly installed PEX is expected to last several decades. Manufacturers often offer 25 year warranties when their pipe and fittings are used together.
PEX resists scale and corrosion, flexes with temperature changes and has fewer joints. Copper is very durable but can develop pinhole leaks in some water conditions and costs more to install.
We install high-quality PEX piping from reputable manufacturers such as Uponor (PEX-A), Viega (PEX-B) and Zurn (PEX-B). We also work with other trusted brands like SharkBite for fittings, so the best materials are used for your installation.
