Our plumbers are skilled in careful copper soldering and installation, ensuring a robust and reliable plumbing system that will last for decades, often outliving the home itself when properly maintained.

PEX-A is the most common replacement for polybutylene because it is flexible, scale resistant and easy to route. We use Uponor PEX-A with expansion fittings that do not restrict flow. New lines run from the main shutoff to every fixture, water heater and appliance. Most homes are completed in two to four working days.
Copper Pipe Replacement in Derry

We provide careful copper pipe installation services across Derry.

Winterizing unused buildings, draining outdoor faucets and keeping heat on prevent most of the freeze damage plumbers see. The result is a dependable, modern supply system.

Frequently Asked Questions About Polybutylene Plumbing Replacement in Derry
Most PEX replacements of polybutylene cost $5,000 to $12,000 for an average home. Copper costs more, and yard service lines add $1,500 to $4,000.
Water in much of New Hampshire is soft and often slightly acidic, which can slowly corrode copper pipe and cause pinhole leaks. While hard water doesn't directly cause polybutylene to fail like chlorine does, it can contribute to scale buildup within the pipes. This buildup can reduce water pressure and potentially worsen problems if the pipe material is already compromised.
You can, but the rest of the system is aging the same way. Patching often leads to another leak elsewhere, so full replacement is the permanent fix.
FVR Plumbing stands behind our work with comprehensive warranties on both materials and labor for polybutylene plumbing replacement. The specific warranty details will be outlined in your service agreement, providing you with peace of mind for your new plumbing.
Common signs include frequent leaks, especially pinhole leaks, discolored water, low water pressure, or visible cracks in the gray or blue plastic pipes and fittings. If your home was built between 1978 and 1995 and has these pipes, replacement is highly recommended.
Look for gray, flexible plastic pipe at your water heater, under sinks or near the main shutoff, often stamped PB2110. Homes built from the late 1970s to mid 1990s are most apt to have it.
We use high-quality, industry-leading brands for our replacement materials, such as Uponor AquaPEX or Viega PEX for PEX systems, and reputable manufacturers for copper piping. We ensure all materials meet or exceed industry standards for durability and performance.
Most homes take two to four days for plumbing, plus a day for drywall patching. Water is usually restored each evening.
