Signs of a Failing Water Service Line
- Wet, soggy, or unusually green strip of yard between meter and house
- Steady drop in water pressure throughout the home over time
- Water bill spiking with no change in usage
- Brown or rusty water from cold taps that does not clear quickly
- Audible water running near the meter when no fixtures are on
- Galvanized service line on a pre-1980s home (still in service in many older Pierce County homes)
- Lead service line (rare in this area but worth confirming on very old homes)
- Sinkhole or settling along the line path
Diagnosis Before Replacement
Not every pressure or flow problem is a failing service line. Before quoting a replacement, we check:
- Pressure at the hose bib closest to the main
- Flow at the meter
- Whether the issue affects hot, cold, or both
- Galvanized supply piping inside the house (often the actual culprit, fixed by a whole-home repipe, not a service line replacement)
- Pressure regulator condition
- Water meter functionality (sometimes the issue)
If the diagnosis points to the service line, we proceed with a replacement quote. If it points to interior piping, the regulator, or a fixture issue, we tell you and quote that instead.
Replacement Methods
Open-Cut (Trench)
The traditional method. We trench from the meter to the house entry point, run new line in the trench, connect at both ends, pressure-test, and backfill. Standard approach when the path is across yard with no major obstructions and depth is reasonable.
Trenchless (Pipe Pulling / Directional Boring)
When the line crosses driveway, hardscape, mature landscaping, or significant obstacles, trenchless methods minimize surface disruption. We bore a small path or pull new line through the old line's footprint with two access pits at each end. Higher per-foot cost, but often less expensive overall once you factor in the surface work the homeowner avoids restoring.
Material Choices
- HDPE (high-density polyethylene): Standard for many trenchless and direct-bury water service replacements. Continuous, corrosion-resistant, and well-suited for long underground runs.
- PEX: Used where approved and appropriate for the application, routing, and local requirements.
- Copper: Not our standard residential recommendation because cost is usually prohibitive. If a jurisdiction, commercial scope, or special condition requires copper, we address it case by case.
Permits, Locates, and the Public Right-of-Way
Water service line replacements require a plumbing permit in every jurisdiction we work in. Some jurisdictions also require coordination with the public works department or water utility for the connection at the meter. We pull the permit, schedule the inspection, and call 811 for utility locates before any digging. You should not have to manage any of that.
Most homeowners own the service line from the meter to the house, even when part of it is in the public right-of-way. A utility's responsibility usually stops at the meter. We confirm the boundary in writing with your jurisdiction before quoting if there's any question.
What It Costs
Pricing varies by length, depth, surface above the line (yard vs. driveway vs. landscape), and method (open-cut vs. trenchless). We quote flat-rate before any work, walk you through the line items, and include the permit and utility locate. Basic backfill is included. Sod, landscaping, asphalt, concrete, hardscape, and finish restoration are included only if specifically listed in the written scope. Free estimate. Financing available.
