Why Choose FBL Plumbing for PEX Pipe Installation in Castro Valley, CA?
PEX piping offers better freeze resistance than copper or CPVC. Mountain and foothill homes in Northern California see real winters, so pipes there need insulation, heat tape, or careful draining when a cabin sits empty. We make sure your new PEX system is installed correctly to maximize that benefit.
- Cost-Effective, PEX is usually less expensive to install than copper, saving you money on labor and materials.
- Corrosion Resistant, Unlike metal pipes, PEX does not corrode or develop pinhole leaks from hard water.
- Durability, PEX is highly resistant to corrosion, scale buildup and chlorine, common problems that degrade older metal pipes.
