Your Go-To Choice for PEX Pipe Installation in Great Falls, MT
DFV Plumbing installs PEX water supply lines for homeowners replacing failing copper, galvanized or polybutylene plumbing. PEX flexes around framing, needs fewer fittings and resists the scale buildup that hard water causes in metal pipe. Many homes rely on private wells, and water quality can vary a lot from one property to the next. We plan routes that limit wall openings and finish with a full pressure test.

PEX-A vs. PEX-B Installation in Great Falls
We offer installation for both PEX-A and PEX-B piping and understand the distinct 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 Great Falls can help you decide which type of PEX suits your project, considering factors like budget and application.

Polybutylene Replacement With PEX in Great Falls, MT
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.
Whole-Home PEX Repiping in Great Falls
If your home has old, corroded or leaking pipes made of galvanized steel or polybutylene, a whole-home PEX repipe is an effective solution. We remove the outdated piping and install a complete PEX system, improving water pressure and water quality and eliminating costly leaks. This complete service leaves your entire plumbing system modern, efficient and built to last for decades in your Great Falls home.
PEX Repipe Cost Comparison in Great Falls, MT
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 together.
Hydronic Heating with PEX in Great Falls
PEX is also a leading choice for hydronic heating systems, including radiant floor heating. Its ability to withstand high temperatures and resist corrosion makes it perfect for circulating hot water. If you are considering radiant heat for a specific area of your home or business in Great Falls, PEX is the pipe of choice.
PEX for Water Line Replacement in Great Falls
When your main water line from the street to your home needs replacement, PEX is an excellent option. Its flexibility allows for easier trenchless or minimal-dig installations, reducing disruption to your yard in Great Falls. PEX main lines handle ground movement and resist corrosion better than rigid pipe. Rocky ground, clay and gravel are all common in Montana, and rock can make trenching for sewer and water lines slow and expensive.
PEX-A, PEX-B, and PEX-C Systems in Great Falls, MT
DFV 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 Great Falls, MT.
