Leak Detection in Tempe, AZ
Most leak detection calls in Tempe start the same way: a water bill that climbed for no obvious reason, or a meter that keeps turning with everything shut off.
Leak detection in Tempe is about finding a leak that isn't visible yet, usually a line running under a slab, inside a wall, or between the meter and the house. The two most common real signals are a water bill that's climbed without any change in household usage, and a water meter that keeps spinning even after every fixture in the house has been shut off.
According to the City of Tempe's own water quality data, hardness here averages 15 grains per gallon, and that mineral scale can mask a small leak's signature for a while before the leak grows large enough to be obvious. That's exactly why electronic and acoustic leak tracing matters here: it finds the leak's actual location before anyone starts cutting into a wall or a slab on a guess.
How We Find a Hidden Leak
Electronic Leak Tracing
Acoustic and electronic equipment listens for the specific sound a pressurized line makes at the leak point.
Meter Testing
Isolating the meter with everything else shut off confirms whether the leak is inside the house or between the meter and the street.
Thermal Imaging
A hot-water line leak under a slab often shows up as a warm spot a thermal camera can locate before any concrete is touched.
Pressure Testing
Isolating sections of the plumbing system narrows down which line is actually losing pressure.
The Water Bill Went Up and Nothing Changed
A lot of the calls we get start with almost the same sentence: the water bill went up and the household didn't change how it uses water. The next thing people usually check is the meter itself, since a meter that's still turning with every fixture in the house shut off is one of the clearest signs of a hidden leak anywhere on the property.
A warm, damp spot on the floor with no other explanation is the other common version of this, especially when it's a hot-water line leaking under a slab. Either signal is worth a real inspection before anyone assumes it's just an old meter or a wet-weather fluke.
Signs Worth Calling About
Rising Water Bill
A bill that climbs with no change in usage is one of the most reliable early signals of a hidden leak.
Meter Still Turning
A water meter that keeps moving with every fixture in the house off points to a leak somewhere on the property.
Warm Floor Spot
An unexplained warm patch on the floor usually means a hot-water line leaking underneath.
Damp Wall Or Ceiling
A damp patch with no obvious plumbing fixture nearby can mean a slow leak inside the wall cavity.

Common Questions
Start with the meter: shut off every fixture in the house and see if it's still turning. If it is, the leak is somewhere on the property and worth a real inspection rather than waiting for another bill.
Yes, that's the point of electronic and acoustic leak tracing. We locate the leak's position first, so any cutting that does happen is targeted, not exploratory.
It can. Mineral scale from Tempe's hard water sometimes masks a small leak's signature for a while, which is part of why we lead with equipment rather than a purely visual check.
Leak detection covers any hidden leak, including walls, ceilings, and the line between the meter and the house. A slab leak specifically means the leak is in a line running under the concrete foundation, which is its own service.
