Polybutylene Replacement With PEX in Kennewick, 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 insure and sell.

Uponor PEX System Installation in Kennewick
FHN Plumbing often installs Uponor PEX systems, a leading brand known for high-quality, durable PEX-A piping. Uponor's ProPEX expansion fittings create strong, reliable and leak-resistant connections, ideal for the demands of a home's plumbing. We recommend Uponor for its long track record and longevity, giving Kennewick homeowners peace of mind about their plumbing investment.
PEX Repipe Cost Comparison in Kennewick, WA
PEX repipes usually cost less than copper repipes because the material is less expensive and installs faster. The total depends on the number of bathrooms, the home's size and how accessible the attic and walls are. Drywall patching and texture matching are sometimes included or quoted separately. We give you a detailed estimate so you can compare PEX-A, PEX-B and copper options side by side.
PEX Main Water Line Installation in Kennewick
The main water line brings water into your home, and a failing one can cause major issues. We provide professional PEX main water line installation, replacing old, damaged lines with durable PEX. This upgrade improves water flow, reduces the risk of future leaks and offers strong resistance to ground shifting and corrosion. Our team ensures proper trenching and the connection to your municipal supply.
Copper to PEX Conversions in Kennewick
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Many rural Washington homes rely on private wells, and some carry iron, manganese or other minerals that call for testing and treatment. Once a home has had several pinhole leaks, more often follow. Converting to PEX stops the cycle and reduces the risk of hidden water damage. We use approved transition fittings wherever new PEX connects to existing copper stubs or valves.
