The whole property

Leak detection across a Mesa property

Leak detection from Trident Plumbing & Drain, arranged through our North Phoenix office, is not limited to one kind of leak. The search covers fixtures and water heaters, piping inside walls and ceilings, the supply line outside and plumbing beneath the slab.

That breadth is what separates it from slab leak repair. The local slab leak repair guide begins once a leak under the concrete has been confirmed and focuses on access and repair choices. Leak detection comes earlier, while the source is still unknown.

Gauge the urgency

An active leak or a slow, hidden one

Water spraying from a pipe, dripping through a ceiling or spreading across a floor is an emergency. Shut the main valve if it is safe to reach, keep clear of wet areas near electrical equipment and request emergency service rather than a detection appointment.

Slow, hidden leaks are different. A stain that grows over weeks, a musty smell or water use that creeps up without explanation calls for a planned search. Note when you first noticed the change so the inspection can follow how it developed.

Equipment and fixtures

Leaks around water heaters and fixtures

Moisture near a water heater can come from a fitting, a valve or the tank itself, and each leads to different work. Tell the office whether the water appears at the top, around the base or along nearby piping, and whether hot water has changed.

Under sinks and around toilets, a slow drip at a supply connection or drain joint can soak a cabinet floor or flooring before it is obvious. Checking these points is a sensible step before searching walls or the slab.

Commercial properties

Hidden leaks at businesses and managed properties

In a shop, office or multi-unit building, a leak may show in one space while the pipe runs through another. Tell the office which rooms or units are affected, which share walls or ceilings with them and whether any area cannot be used normally.

Arrange access to every space the plumbing serves, not only the one with the stain, and name the person who can approve the repair. Trident provides commercial plumbing, so the follow-up work can be discussed alongside the findings.

When it comes back

If a stain or damp area returns where a leak was fixed before, share the earlier repair details, when the moisture came back and whether it looks the same. The cause may be the same pipe, a nearby section or a different source showing in the same place.

If the search confirms a leak in piping beneath the slab, the slab leak repair guide covers direct access and rerouting. Leaks in walls, at fixtures or on the line outside lead to their own repairs, including wider repiping when the piping's condition supports it.

The City's leak check

Run the meter test before the search begins

The City lays out a short leak check. Compare this month's use with earlier months, then turn off every faucet, toilet, irrigation zone, washing machine and dishwasher and watch the water meter. If it keeps registering flow, water may be moving through your plumbing. Next, check the sources the City lists as common: toilets, irrigation systems, water softeners, hose bibs and pool autofill lines. Mesa's new smart meter displays include a current flow rate, which makes small movement easier to spot.

Then sort out whose leak it is. The City asks you to call it if water is leaking from the meter box or surfacing in the street. A leak on your property beyond the meter, at a fixture or in the irrigation is a job for a plumber. That is where our search starts: fixtures and the water heater first, then walls, ceilings, the slab and the line from the meter to the house. In a city where more than half the homes predate 1990, earlier repairs are worth mentioning.

Leak search costs

Factors in the price of a leak search

A leak search is priced by the time and tools it takes to find the source. These factors make the difference.

Ask your insurer early whether your policy covers locating the leak and the access work, since a policy may handle them separately.

  • Whether the meter test shows constant flow or the leak comes and goes.
  • The likely area: a fixture, a wall or ceiling, the slab or the yard line.
  • Hot side or cold side, and how many lines have to be isolated.
  • How much has to be opened to confirm the leak.
  • Finding more than one leak in the same search.

Ask our team
Should I stop using a fixture I think is leaking?

If using it spreads water, yes. Otherwise, note what happens when it runs. That observation helps the plumber narrow the source.

Can a leak in one unit show up in another?

Yes. Water can travel through shared walls, ceilings and floors, so a stain may appear in a different space from the leaking pipe. Arrange access to neighboring areas as well.

Is a small stain worth investigating?

Yes. A stain that keeps coming back is worth checking even when there is no puddle. Water leaking inside a wall or beneath flooring can damage the materials around it while the leak itself stays hidden.

Does a musty smell mean there is a leak?

Not by itself, but it is worth reporting, especially alongside stains, damp spots or unexplained water use. The inspection considers it with the other clues.

Can my smart meter tell me I have a leak?

It can help. The City says its smart meters read use continuously and can detect water running around the clock, sudden spikes and gradual increases, and that staff review the data and contact customers about potential issues. A meter alert tells you water is moving, not where it is going.

Can a water softener cause high water use?

It is on the City's list of common leak sources to check, along with toilets, irrigation, hose bibs and pool autofill systems. If the meter keeps moving with the house shut down, have the softener checked along with the other sources.
