Is it a slab leak?
Where Tempe fits
Tempe is home to Arizona State University and Tempe Town Lake on the Salt River. It is surrounded by neighboring cities, and its housing mixes mid-century homes, rentals and newer infill.
Slab leak repair and replacement in Tempe
Tempe is a mid-sized city in Maricopa County, and slab leak calls come in from it around the clock. Tempe had 184,213 residents at the 2020 Census. A good part of Tempe was built before 1990, on slabs, with the plumbing running beneath the floor.
Metal lines this old have usually seen decades of hard water, and the weak points tend to be joints and thin stretches. HOA communities and attached homes are a big part of the housing. The technician plans around that.
With pools and drip systems in so many yards, those get checked before the slab. Hard caliche layers are common in the ground around slabs. It is useful to know this before anything is opened. Since there are many ways for water to escape, doing the checks in the right order matters more than the tools.

Unexplained water use
A bill that stays up with no change at home means water is going somewhere out of sight. The slab is one possibility.
Look at the meter with all water off before you phone, and pass on the result.
Ruling out the look-alikes
Several things can push up a bill or turn a meter in Arizona: a slab leak, a pool fill valve, drip irrigation, a buried yard line, a swamp cooler or a toilet that keeps running. Each is checked in order before the slab is blamed.
The first meter reading
Movement with the house quiet is the result to report when you call.
Running water when everything is off
If you hear a trickle with every tap closed, water may be escaping a line under pressure. Night is when it is easiest to hear.
The order of checks
These checks happen at the meter and the sprinkler controller. Quit once a step explains the water.
How a slab leak is located
Keep the meter reading and the year the house was built close at hand.

Common questions from Tempe
Why do pinholes appear in older homes?
Metal lines in Tempe homes built before 1990 have usually seen decades of hard water, and the joints and thin stretches are where a small hole opens. What the line is made of is checked when it is exposed.
Can a leak run for years unnoticed?
It can, with only a slow rise in the bill. That is why a meter reading with everything off is worth taking, even when nothing in the Tempe home looks wet.
Can you work in a Tempe townhome with shared walls?
Yes. Attached homes are a big part of Tempe's housing, and shared walls mean access needs planning. Tell us about the layout when you call.
Does my Tempe association have to approve the repair?
Check your documents, as we cannot state association rules. In Tempe, where attached homes and HOAs are common, the technician can supply what was found so you can take it to the association.
How do I watch the pool level?
Put a mark on the tile at the waterline and look again after 24 hours. Pool repair is outside what we do, but the reading helps us interpret the meter.
How is a slab leak located in Tempe?
The technician isolates hot, cold and yard lines, pressure tests each, then uses listening equipment and a thermal camera to mark the spot. It is the same in Tempe as anywhere.
Why are the lines isolated first in a Tempe home?
Knowing which line is losing water means searching a short stretch of pipe instead of the whole Tempe house. That matters in attached Tempe homes, where access is limited and openings should stay small.
Are most homes in Tempe on slabs?
A good part of Tempe was built before 1990, on slabs, with the plumbing running beneath the floor. Lines of this age have had a long time to wear, and the likely failure points are joints and stretches that run through harsh ground.
Can you come to Tempe the same day?
Same-day visits are the aim for Tempe and the rest of Maricopa County. Timing depends on crew availability that day.
Slab leak repair and replacement services in Tempe
When only one stretch of pipe has failed, repair is the shorter path for a Tempe house. Pipe at the end of its service life is replaced, either by rerouting around the slab or by repiping the house. The choice is made after the leak is located, with the reasons explained.
