Reliable Water Line Repair Services in Derry, NH

PEX Water Line Repair in Derry, NH

PEX (cross-linked polyethylene) piping is a flexible, durable, and corrosion-resistant option more and more used in homes across Derry, NH. While PEX is less prone to leaks than older materials, damage can still occur from improper installation, rodent chewing, or impact. Our team is fully experienced in PEX repair, using specialized crimping tools and fittings to make strong, leak-proof connections. We ensure your PEX system continues to perform well.

Water Line Repair at the Meter in Derry, NH

Leaks often start at the compression fittings and couplings right next to the meter box. Shifting soil and heavy traffic over the box can work loose those joints over time. We determine whether the leak is on the utility side or the customer side, since the water provider is in charge of the meter and the pipe before it. When the leak is yours, we replace the fittings and the customer shutoff valve on the same trip.

Commercial Water Line Repair in Derry, NH

Businesses in Derry, NH rely on a steady and clean water supply. A commercial water line break can disrupt operations, lead to property damage, and even violate health codes. FVR Plumbing provides fast and professional water line repair for commercial properties, understanding the need for limited downtime. We handle larger diameter pipes and more complex systems, so your business's water service is quickly restored to full function, minimizing the impact on your bottom line.

Trenchless Water Line Replacement in Derry

If your service line runs under a driveway, pool deck or mature landscaping, trenchless replacement can save a lot of restoration cost. We dig small pits at each end and pull new HDPE or PEX pipe through using a pneumatic boring tool or pipe pulling equipment. The process usually takes one day. You keep your pavers and trees, and the new line carries a long manufacturer warranty.

Emergency Water Line Break Repair in Derry, NH

A full break can flood a yard, wash out soil under walkways and leave your home without water. Our emergency crews shut off the supply, find the break and set up a temporary bypass when the repair will take more than a few hours. Most emergency breaks are repaired the same day. We also document the damage with photos for your insurance or HOA.

Pressure Regulator and Shutoff Repair in Derry

Many water line problems are made worse by high incoming pressure. A failed pressure reducing valve can push well over 80 psi into your plumbing, which stresses the service line and every fixture. We test static pressure with a gauge and replace worn regulators from brands like Watts and Zurn Wilkins. We also swap seized gate valves for full-port ball valves so you can shut the water off quickly in an emergency.

Main Water Line Leak Repair in Derry

Most main line leaks show up as a soggy strip of yard, a sudden jump in your water bill or a meter dial that moves with every fixture off. We verify the leak by isolating the house shutoff and watching the meter. Then we use ground microphones to find the exact spot. A single section is cut out and replaced with repair couplings or a new length of pipe, and the line is pressure tested before we backfill.

Galvanized Water Line Replacement in Derry, NH

Many homes built before the 1970s still have galvanized steel service lines that rust from the inside. Water in much of New Hampshire is soft and often slightly acidic, which can gradually wear down copper pipe and cause pinhole leaks. Hard water speeds up scale buildup, which restricts flow and causes rust-colored water. Patching galvanized pipe rarely lasts because the surrounding pipe is just as corroded. We usually recommend replacing the full run from meter to house with copper or PEX, which restores pressure and ends repeat leaks.
