Irrigation and Yard Line Repair in Shoreline
Drip lines and sprinkler supply pipes are often shallow and easy to break during landscaping or by roots. A broken irrigation main can run up a water bill fast in summer. We repair PVC and poly irrigation mains, replace failed backflow connections and fix the supply line to the valve manifold. We can also reroute vulnerable lines away from trees.

Galvanized and Polybutylene Line Replacement in Shoreline
Galvanized steel pipe rusts from the inside, and polybutylene pipe becomes brittle and splits without warning. If your underground service is either material, repairs are often temporary. We replace the line with PEX or Type K copper, often by pulling the new pipe through the old path to limit digging. A new line restores pressure and removes the risk of repeated leaks.
Trenchless Underground Pipe Repair in Shoreline
For homeowners in Shoreline looking to minimize disruption to their landscaping, FHN Plumbing offers trenchless underground pipe repair. This method involves creating small access points to repair or replace pipes without extensive digging. It's a faster, less invasive solution for certain types of pipe damage, saving time and money on property restoration.
Sewer Line Underground Repair in Shoreline, WA
Underground sewer line issues, often caused by tree root intrusion or shifting soil, require specialized attention. FHN Plumbing offers complete sewer line repair, including traditional excavation and trenchless options like pipe bursting or CIPP lining. We make sure all repairs meet Washington environmental and plumbing codes.
Water Main Underground Repair in Shoreline
A leaking or broken water main can lead to major water loss and property damage. FHN Plumbing provides expert repair for underground water mains, using durable materials like PEX or copper for a long-lasting fix. We can promptly locate the break using non-invasive methods and restore your home's water supply with minimal disruption.
Underground Sewer Line Repair in Shoreline, WA
Buried sewer laterals crack from root intrusion, soil settling and age. We camera the line to find the exact spot, then excavate and replace the damaged section with PVC. Shielded couplings make a watertight connection to the existing pipe. We confirm proper slope and flow before backfilling and compacting the trench.
Pool and Outbuilding Supply Line Repair in Shoreline, WA
Many properties have buried water lines feeding a pool auto-fill, a guest house, an outdoor kitchen or a detached garage. These lines are often longer than the main service and harder to locate. We use tracer wire and acoustic equipment to find leaks along the full run. Repairs are made with direct-bury rated pipe and tested before we close up.

Underground Pipe Repair Cost Comparison in Shoreline, WA
A single point repair on a shallow water line is the most economical option. Pipe bursting or pulling a new line through the old path costs more but avoids open trenching and long-term risk. Full trench replacement is sometimes needed when the old route is blocked or the pipe is too damaged. We explain each method and its cost so you can choose the best value.
