Slab leak detection and repair in Tempe, AZ

Trident Plumbing & Drain investigates leaking water lines beneath concrete slabs in Tempe. The work starts with locating the affected plumbing and understanding its condition. Those findings shape whether a focused repair, reroute or broader piping work should be discussed.

Our North Phoenix office coordinates service for your Tempe property. Describe the symptoms and any known leak history when contacting us. If someone has already inspected the area, share the findings so the conversation can start with the information you have.

Keep the clues together

Common signs of a slab leak

Unexplained warm or damp flooring, a change in water pressure and unexpected water use can point to a hidden plumbing issue. Running-water sounds while fixtures are off are another concern. Cracks or musty odors may also be worth reporting during the assessment.

Note the areas involved and whether the signs are new, persistent or returning after earlier work. A recurring symptom does not automatically identify the same damaged pipe. The inspection needs to connect the current observations to the condition of the plumbing beneath the home.

Locate and compare

Consider a targeted repair or a reroute

Leak detection helps establish the affected line and the problem being addressed. Once the leak is located, Trident reviews the available options. A targeted repair addresses a particular damaged section; rerouting changes the path of the affected water line.

Ask why the proposed approach fits the pipe's location and condition. Review where access is required, which connections are included and what work would happen elsewhere in the property. Understanding those differences helps you compare practical repair scopes rather than choose a method by name alone.

Define the extent

When broader repiping enters the discussion

The extent of damaged piping may call for a wider solution than repairing one spot. Repiping should be discussed in relation to the lines affected, their condition and the findings from the assessment. Ask which part of the system would be replaced.

Bring any records of earlier leaks or pipe repairs to that conversation. The recommendation should explain why broader work is relevant and what it includes. Clarify the boundary between the plumbing work, access openings and any restoration needed after the repair.

The risks of delaying slab leak repair

Water escaping beneath a slab can affect flooring and nearby building materials. Report ongoing or spreading moisture when you request service, along with any change since the first signs appeared. An active leak deserves attention even if its exact location is not visible.

Discuss both the immediate plumbing concern and what needs checking around the affected area. Keep a record of the completed repair and any follow-up recommendations. If symptoms persist or return, describe the new pattern to the office so the next assessment has that history.

Find it first

Use the City's meter test to narrow the search

The City's Find and Fix Leaks guide walks through an isolation test. With all water use off, open the meter lid near the street and watch the small red dial, which moves when water is flowing on the property. If the home has a pool, shut off the auto-fill first, since the City calls it one of the most common leak spots in Tempe. Next, close the irrigation valve. Then close the house shut-off. If the dial stops at that point, the leak is inside the home.

If the dial keeps spinning with the house valve closed, the City says the leak is in the service line and to call a professional who specializes in service lines. Either way, City Code makes the water customer responsible for the lines on the property. The City's WaterSmart portal can also alert single-family households to steady use that runs continuously for at least 72 hours, though the City notes an alert does not prove a leak, and customers who get one can ask conservation staff for a leak consultation. It is also common, the City says, for a home to have more than one leak.

Repair scope

Why slab leak repairs vary in cost

Cost depends on the leak's location and the state of the pipe around it. The City's code shapes the scope too: it exempts stopping a leak from permits only when no pipe, fittings or valves are replaced, and it does not allow plastic water pipe to be left exposed outdoors, which matters if a reroute runs outside.

For a reroute or another large repair, ask about GreenSky® financing.

  • How precisely the leak can be located before the floor is opened.
  • Opening the slab for a spot repair, or running new pipe overhead instead.
  • The reroute's path, including any exposed outdoor run, which must be metal.
  • Flooring removal and restoration afterward.
  • Whether a permit and inspection apply to the work.

Leak checks

Before the floor is opened in a Tempe home

The City publishes a meter test for hidden leaks and spells out who maintains which pipe.

1 minute

Turn off everything that uses water, photograph the meter, wait at least a minute and photograph it again. If any numbers changed, you may have a leak.

Answers before you book

Questions about
slab leak repair in Tempe.

Questions about slab leak repair in Tempe? Start here, or tell us what is happening at your home.

Ask our team
Is rerouting required for every slab leak?

No. A focused repair, reroute or wider piping solution may fit different findings. The damaged line, its location and its condition guide the recommendation.

What should a repiping recommendation explain?

Ask which lines need replacement, how the findings support that scope and what access is involved. Clarify any restoration or other work outside the plumbing repair.

Does a returning damp spot mean the old repair failed?

Not necessarily. Explain the previous repair and current symptoms. The affected plumbing needs checking before identifying the cause of the new or recurring moisture.

Can I request an assessment before water is visible?

Yes. Unexplained water use, warmth underfoot, pressure changes or running-water sounds can be reasons to discuss an inspection even without an obvious wet area.

How do I check my meter for a hidden leak?

Turn off everything that uses water inside and out. Open the meter lid near the street, photograph the meter face, wait at least one minute and photograph it again. If the numbers or the small red dial moved, water is flowing somewhere on the property. The City's guide then has you shut off the pool, the irrigation and the house in turn to narrow it down.

Does a slab leak repair need a permit in Tempe?

The City's administrative code exempts stopping a leak when no pipe, fittings, valves or fixtures have to be removed and replaced. A repair that replaces pipe, or a reroute, is outside that exemption. The City also says it is the homeowner's responsibility to make sure low-lead materials are used when plumbing is repaired.
