Straight Flush Plumbing slab leak detection and pipe repair in Surprise, AZ

Most Leaks Don't Announce Themselves

A burst pipe is obvious. The expensive leaks are the quiet ones — a pinhole in a copper line under the slab, a supply line weeping behind a bathroom wall, a service line losing water between the meter and the house. They run for weeks or months, and by the time something visible shows up, the damage is already done.

Homes across Surprise and the West Valley are especially prone to this. Copper lines installed through the 1990s and 2000s are now old enough for pinhole corrosion to start, hard water accelerates it from the inside, and soil movement under a slab-on-grade foundation stresses the joints. That combination is why slab leaks are one of the most common calls we take.

Signs You May Have a Hidden Leak

No single one of these confirms a leak. But if you're seeing two or more, it's worth a call before it becomes a flooring repair.

Your water bill jumped with no change in how you're using water

A warm or hot spot on the tile or floor you can feel barefoot

You hear running water with every fixture in the house shut off

The water meter keeps creeping even with everything turned off

Flooring that's lifting, buckling, cracking, or separating

Carpet or baseboards that stay damp with no source above them

A musty or mildew smell that keeps coming back after you clean

Water pressure that's dropped off across the whole house

Stains on drywall or ceiling that return after you patch them

Leak Detection

Finding the leak is the job. Anyone can cut a hole and look — the point of proper detection is to know exactly where the water is coming from before the first hole gets cut. We isolate the system, confirm the leak is real, then pinpoint it.

How We Locate It

  • Meter and static pressure testing to confirm a leak exists and separate supply from drain
  • Acoustic listening equipment to hear pressurized water escaping through concrete or drywall
  • Thermal imaging to map hot-water lines and find temperature anomalies under flooring
  • Line tracing to map where the pipe actually runs, which is rarely where the plans say
  • Isolating hot from cold so you're not paying to repair the wrong line

Slab Leak Repair

A slab leak is a water line failing underneath your foundation. In the West Valley it's usually a pinhole in a copper line — hard water eats it from the inside, soil movement stresses it from the outside, and eventually it gives. The warm spot on your floor is a hot-water line. A cold-water slab leak often shows up as a bill increase and nothing else.

Your Three Repair Options

  • Spot repair — open the slab at the leak and replace that section. Best when it's a single, accessible failure in otherwise sound pipe.
  • Reroute — abandon the line under the slab and run a new one through the wall or attic. No jackhammer, and the abandoned line can't leak again.
  • Whole-home repipe — when this isn't the first leak. If a line has failed twice, the rest of that pipe is the same age and the same water.

We tell you which one we'd do in our own house, and why. You get the price for each before you decide.

Pipe Repair

Pipe fails for reasons you can usually name once you know what's in the walls — corroded galvanized steel in older Surprise and West Valley homes, pinhole corrosion in copper, polybutylene that splits at the fittings, or CPVC that's gone brittle. We identify what you have, repair what's failed, and tell you honestly whether the rest of it has years left or is on the same clock.

What This Can Involve

  • Cutting out and replacing failed sections of supply line
  • Repairing leaks at fittings, valves, angle stops, and hose bibs
  • Replacing corroded galvanized runs with copper or PEX
  • Pressure-testing the repair before we close anything up
  • Telling you what's left in the system, not just what we fixed

Water Service Line Repair & Replacement

The service line is the pipe running from your meter to the house, and it's buried the whole way. When it fails you'll usually see one of three things: a soft or unusually green patch in the yard, pressure that's dropped at every fixture at once, or a meter that keeps turning after you've shut the main valve at the house.

We locate the break, confirm whether the line is worth repairing or has reached the end of its life, and handle replacement — including permitted work where the city requires it.

Repiping & When It's Actually Worth It

Most homes don't need a repipe, and we'll say so. But there's a point where repairing is throwing money at pipe that's going to fail again, and it's usually recognizable.

Signs a Repipe Is the Better Money

  • This is the second or third leak in the same system
  • The home still has original galvanized steel supply lines
  • You have polybutylene — gray or blue flexible pipe with crimped fittings
  • Pressure and flow are poor at every fixture, not just one
  • You're already opening walls or ceilings for another repair

We repipe in PEX or copper depending on the house and what you want, quote it flat-rate up front, and pull the permit. If a targeted repair is genuinely the smarter call, that's what we'll recommend instead.

Think You Have a Leak? Do This First

You can confirm a leak yourself in about twenty minutes, before you call anyone.

  • Shut off every fixture and appliance that uses water
  • Find the water meter and photograph the reading
  • Wait 20 minutes without using water, then check it again
  • If it moved, you have a leak — now shut the main at the house
  • Still moving? The leak is between the meter and the house
  • Photograph any damp spots, stains, or warm areas on the floor
  • Pull rugs and furniture off damp flooring to limit the damage
  • Call before anyone cuts into a wall, slab, or ceiling

Leak Detection & Pipe Repair FAQs

The clearest sign is a warm spot on the floor, which points to a hot-water line under the slab. Others include the sound of running water with everything off, a water bill that jumped without a change in usage, a meter that keeps moving with all fixtures closed, damp carpet with no source above it, or flooring that's started to lift or crack. A cold-water slab leak often shows up as nothing but the bill, which is why the meter test matters.

That's the entire point of proper leak detection. We use acoustic listening equipment, thermal imaging, and pressure isolation to narrow the leak to a specific location before anything gets opened. Detection is non-destructive. The repair may require opening a small area, but you shouldn't be paying someone to guess and cut.

It depends on what's involved, which is why we diagnose before we quote. What we can tell you is that you get one flat-rate price before any work begins, and it doesn't change afterward. You'll know the number for detection and the number for each repair option before you decide anything.

A spot repair makes sense when it's the first failure, the location is accessible, and the rest of the pipe is in good shape. A reroute makes sense when the line is hard to reach, when opening the slab means tearing out finished flooring, or when you'd rather that section never be able to leak again. If it's the second leak in the same system, we'll usually talk about a repipe instead — the rest of that pipe is the same age and carrying the same water.

It's corrosion working from the inside out. Hard, mineral-heavy water moving through copper year after year wears the pipe wall thin in spots until it perforates. Under a slab you also get soil movement stressing the line and abrasion where the pipe contacts concrete. It's why copper installed in the 1990s and 2000s across the West Valley is reaching the age where leaks start showing up.

It varies by policy. Many policies cover the resulting water damage and the cost of accessing the pipe while excluding the pipe repair itself, but that's a generalization and yours may read differently. Photograph everything, keep your documentation, and call your carrier early. We can provide written findings from the detection to support your claim.

Leaks don't hold steady — a pinhole gets bigger, and the water goes somewhere. Under a slab it can undermine the foundation and saturate flooring; in a wall it can reach drywall, insulation, and framing, and mold follows moisture. The repair gets more expensive the longer it runs, and so does the damage around it. If you've confirmed water is moving with everything shut off, that's a today problem.

If your home was built roughly between the late 1970s and mid 1990s and the supply lines are gray or blue flexible plastic with crimped metal or plastic fittings, that's likely polybutylene. It tends to fail at the fittings, usually without warning. We'll confirm what you have and tell you honestly whether it needs to come out now or whether you're monitoring it.
