Remodel and Addition PEX Rough-In in Helena
Kitchen and bathroom remodels are a great time to replace old supply lines with PEX.

Additions and guest suites get properly sized lines tied into your existing system. We coordinate with your contractor to keep the project schedule on track.

Whole-Home PEX Repiping in Helena
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 We remove the outdated piping and install a complete PEX system, improving water pressure and water quality and stopping costly leaks. This complete service leaves your entire plumbing system modern, efficient and built to last for decades in your Helena home.
Copper to PEX Conversions in Helena
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Water across much of Montana is moderately hard to hard, especially from wells, so scale buildup in water heaters and fixtures is common. Once a home has had several pinhole leaks, more often follow. Converting to PEX stops the cycle and lowers the risk of hidden water damage. We use approved transition fittings wherever new PEX connects to existing copper stubs or valves.
Leak Repair with PEX in Helena, MT
For individual pipe leaks, PEX can be used to repair or replace sections of damaged piping. Our plumbers can isolate the damaged section and tie in PEX, providing a durable and flexible fix that holds up to future pressures. This targeted approach is cost-effective for localized issues and brings the benefits of PEX to troubled areas of your existing plumbing in Helena, MT.
PEX-A Expansion Fitting Systems in Helena, MT
PEX-A, such as Uponor, uses an expansion tool to stretch the pipe and a ring over the fitting, which then shrinks back into a secure seal. The fittings have a larger inner diameter, so flow restriction is lower. PEX-A is also more flexible and can recover from kinks with a heat gun. It is our favored choice for many full repipes.
Uponor PEX System Installation in Helena
DFV 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 proven track record and longevity, giving Helena homeowners peace of mind about their plumbing investment.
PEX-A vs. PEX-B Installation in Helena
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 Helena can help you decide which type of PEX suits your project, considering factors like budget and application.

PEX-B Crimp and Clamp Systems in Helena
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 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 always be buried or otherwise shielded.
