Vegas water mains.Why they fail and what we do about it.

Most Las Vegas homes built before the mid-1990s have galvanized steel or polybutylene water service lines. Both materials degrade over time — galvanized rusts from the inside out, polybutylene weakens at the fittings. By 25-35 years old, leaks become common. Newer homes (1995+) typically have PEX or copper, which last much longer but can still fail at fittings or from ground movement.

We pinpoint mainline leaks the same way we find slab leaks: acoustic ground microphones, electronic line tracing, and pressure isolation. The goal is to open ONE small area exactly where the leak is — not trench the entire front yard guessing.

Once located, repair options range from single-spot pipe repair (cheapest, fastest) to full mainline replacement (most durable, recommended for older galvanized service). We'll show you both options with honest pricing — no upsells, no scare tactics.

  • Acoustic PinpointIndustrial ground microphones locate the exact leak position underground.
  • Electronic Line TraceMaps where your service line runs from meter to house — no random digging.
  • Pressure IsolationConfirms the leak is on YOUR side (you own and pay) versus the city's side (they fix).
  • Single-Spot RepairOpen one targeted area, fix the leak, patch. Yard mostly intact.
  • Full Mainline ReplacementFor old galvanized or polybutylene service, full replacement with PEX or copper — code-compliant, full warranty.
  • Sod RestorationMost jobs include sod replacement so your yard looks normal within days, not months.

Common Questions

Answersfrom Matt.

My water bill jumped $200 — could it be the mainline?

Possibly. Mainline leaks are one of the most common high-water-bill causes in Vegas. We pinpoint with acoustic and pressure isolation in 30-60 minutes.

Is the leak my responsibility or the city's?

On your side of the meter: yours. On the city side: theirs. Pressure isolation testing confirms exactly which side the leak is on — saves you from fighting the wrong battle.

Should I repair or replace the mainline?

Single-spot repair is cheapest. But if the line is old galvanized or polybutylene, repairing one spot often just buys time before another leak. We give you both options with honest cost comparison.

How long does a full mainline replacement take?

Typical residential service: same day. We dig the trench, lay the new line, connect at the meter and the house, pressure-test, and backfill — usually done before dinner.
