Main Water Line Repair in Longview
The main water line brings water from the public supply to your home. When this line leaks or breaks, it can cause serious water loss, foundation damage, and low water pressure. Our team focuses on diagnosing and repairing main water line issues, from pinpoint leaks to full pipe ruptures, so your home's primary water source is secure. We use advanced detection methods to pinpoint the exact location of the problem, limiting excavation and disruption to your property in Longview. We also check for common issues like root intrusion or shifting soil.

Underground Leak Detection in Longview, WA
Many water line leaks occur underground, making them hard to detect without specialized equipment. Our technicians use advanced acoustic and thermal imaging tools to accurately locate hidden leaks without unnecessary digging. Early detection saves you money on water bills and prevents costly damage to your foundation. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. Once located, we provide a clear repair plan, so the problem is resolved efficiently for your property in Longview.
Water Pressure Restoration in Longview
Low water pressure can be a frustrating symptom of an underlying water line problem, such as blockages, leaks, or a failing pressure regulator. In Longview, if your water pressure has dropped suddenly, it's crucial to have your main water line inspected. We diagnose the cause of low pressure, whether it's mineral buildup restricting flow or a hidden leak, and perform the needed repairs or replacements to restore strong, consistent water pressure throughout your home.
PEX Water Line Repair in Longview, WA
PEX (cross-linked polyethylene) piping is a flexible, durable, and corrosion-resistant option increasingly used in homes across Longview, WA. 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.
Trenchless Water Line Repair in Longview
For some water line repairs, traditional trenching can be avoided. Trenchless repair methods, like pipe bursting or pipe lining, allow us to fix or replace underground pipes with little disruption to your landscaping, driveway, or foundation. This method is often faster and less intrusive than conventional digging, making it a popular choice for homeowners in Longview looking to protect their property. We'll check whether your water line issue is a good candidate for trenchless technology.
Slab Leak Water Line Repair in Longview
Slab leaks, where water lines running beneath your home's concrete foundation leak, are a particularly challenging issue. Newer homes in Longview typically use PEX supply lines, and many older houses have been partially repiped over the years. These leaks can undermine your foundation, leading to serious structural damage. We use specialized listening devices and camera inspections to pinpoint slab leaks precisely and offer repair options including direct slab penetration, re-routing, or pipe lining. Addressing a slab leak quickly in Longview is crucial to prevent extensive, costly foundation damage.
Water Line Repair at the Meter in Longview, WA
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 responsible for 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.

Galvanized Water Line Replacement in Longview, WA
Many homes built before the 1970s still have galvanized steel service lines that rust from the inside. Municipal water west of the mountains in Washington is generally soft, while supplies on the drier east side tend to run harder. Hard water speeds up scale buildup, which restricts flow and causes rust-colored water. Patching galvanized pipe seldom holds up 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.

Frequently Asked Questions About Water Line Repair in Longview
The cost of water line repair in Longview, WA can vary widely, typically ranging from $500 for a minor leak repair to $5,000 or more for a full main line replacement or complex trenchless work. Factors include the location of the leak, the type of pipe, the extent of damage, and whether excavation is required. We provide a detailed, upfront estimate after a thorough inspection.
For water line replacements, we primarily use durable and code-compliant materials such as PEX (cross-linked polyethylene) and copper. PEX is flexible and resistant to freezing, while copper offers excellent longevity and corrosion resistance. The best material for your home in Longview will depend on your specific needs, budget, and local regulations.
Preventing future water line issues involves a few key steps: being mindful of landscaping near buried lines, quickly fixing minor leaks, and considering a whole-home water pressure regulator if your pressure is consistently high. Regular plumbing inspections can also help identify potential problems before they grow. For older homes in Longview, proactive pipe replacement might be the best long-term solution.
Yes, for most major water line repairs or full replacements in Washington, particularly those involving excavation or changes to the main line, a permit from your local city or county authority is typically required. FHN Plumbing handles all necessary permitting so your repair is fully compliant with local building and plumbing codes.
We typically install Type K copper, PEX rated for direct burial or HDPE for trenchless pulls. Each holds up well in most soils when properly bedded. We will recommend the right material based on your soil, line length and budget.
We use only quality, reputable brands for all our water line repairs and installations. This includes trusted names in PEX like Uponor and Viega, and durable copper piping from manufacturers known for their reliability. Our fittings are always code-compliant and selected for their longevity in varied soil and water conditions, for a robust repair.
Most standard water line repairs can be completed within a few hours to a full day, depending on the severity and accessibility of the leak. More complex issues, like trenchless pipe replacement or extensive excavation for a main line, might take 1-3 days. We always aim for the fastest, most efficient fix without compromising quality.
Trenchless water line repair is a method of fixing or replacing underground pipes without extensive digging. Techniques like pipe bursting involve pulling a new pipe through the old one, while pipe lining inserts a new, cured-in-place pipe inside the existing one. It's an great option for preserving landscaping and limiting disruption, especially on properties in Longview with established gardens or driveways.
