Why Choose FVR Plumbing for PEX Pipe Installation in Londonderry, NH?
PEX is only as good as the way it is installed, so we follow manufacturer guidelines for support spacing, bend radius and UV protection. That attention prevents kinks, sagging and early failure.
- Flexibility, Its flexibility allows for fewer fittings and connections, cutting down potential leak points in your plumbing system.
- Freeze Resistant, PEX can expand and contract, making it more resistant to bursting in freezing temperatures than rigid pipes.

Experienced Team
Our plumbers have completed many whole-home repipes and know how to route PEX through tight attics, around ductwork and through finished walls. They plan the layout before opening any drywall.
Safety-First Approach
PEX must be kept out of direct sunlight and away from heat sources like water heater flues, so we sleeve and route it carefully in attics. We also follow distance requirements from the water heater using approved transition fittings.
