Expert PEX Pipe Installation Services in Castle Rock, CO
GFR Plumbing uses both PEX-A expansion fittings and PEX-B crimp systems depending on the project and budget. Many newer homes across Colorado use PEX with manifold systems, which handle freezing better than rigid pipe but still require protection. When copper lines under a slab start to show pinhole leaks, we reroute new PEX through attics and walls. You get a reliable system without tearing up your slab.
Our expertise includes:
- Fixture and appliance PEX hookups
- PEX-A expansion and PEX-B crimp fitting systems installed
- Whole-home PEX repiping services

Full Home PEX Repiping in Castle Rock
If your home has old, corroded or leaking pipes, a full home PEX repipe can drastically improve your plumbing system. We remove outdated galvanized, copper or polybutylene pipes and replace them with durable PEX, upgrading your entire water delivery system. This prevents future leaks, improves water pressure and eliminates the rust-colored water often seen with older piping in Castle Rock.
PEX-B Crimp and Clamp Systems in Castle Rock
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 reliable PEX-B systems. We use a go/no-go gauge on every crimp to verify a proper seal.
Copper to PEX Conversions in Castle Rock
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Many larger systems in Colorado draw on mountain snowmelt that runs fairly soft, while plains communities and groundwater sources often deliver harder water. 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.
