Your main water line carries every gallon of water into your home, and when it fails, the whole house feels it. A buried main line leak can mean wet spots in the yard, dropping pressure, climbing water bills, or no water at all. All Phase Plumbing diagnoses, repairs, and replaces water service lines across the Seattle area.

We use modern locating and leak-detection equipment so we can pinpoint problems and propose targeted fixes, not exploratory digging.

Call (206) 772-6077 to schedule water line service.

Signs Your Water Line Needs Service

  • Sudden drop in water pressure throughout the home
  • Unexpected spike in your water bill
  • Wet, soft, or sunken patches in the yard
  • Discolored water from every tap
  • Sounds of running water with everything off
  • Visible leak at the meter or shutoff

Water Line Repair vs. Replacement

Small leaks or single-point damage can often be spot-repaired without replacing the whole line. Older galvanized or polybutylene service lines that have failed in multiple spots usually warrant full replacement for long-term reliability.

Trenchless Water Line Replacement

Where conditions allow, we replace water service lines using trenchless techniques that preserve driveways, patios, and landscaping. We dig small access pits at each end and pull a new HDPE pipe through, saving you thousands in hardscape restoration.

Schedule Water Line Service

If you suspect a water line problem, don't wait, small leaks become large losses fast. Call (206) 772-6077 and a licensed plumber will diagnose the issue and walk you through repair options.

Water Lines FAQs

Trenchless replacements are often completed in a single day. Traditional dig-and-replace can take 1–3 days depending on length and depth.
Service is typically off for several hours while the new line is connected. We coordinate the shutdown window with you in advance.
The city owns the line to the meter; everything from the meter to your house is yours. We work on the homeowner side and coordinate with the city when meter or shutoff work is needed.
Often not. Trenchless methods need only small access pits. Even traditional excavation is planned to minimize landscape damage.
